Smallpox Vaccine: History and its Lessons

The root of Public health

John snow’s study about the Cholera and his investigation proving the connection between the occurrence of cholera and consumption of water from selected sources helped to establish public health and epidemiology domain as useful as any medical science and helped to establish principles and scope of Public Health. Just in the same way, the eradication of small pox in 1980 due to smallpox vaccination exemplifies how the diseases can be prevented, eradicated and health of the people can be protected.

Among all the stories behind the public health, the story behind the discovery of SmallPox always fascinated since the day I learnt about Smallpox vaccine. This is discovered or at least credited to be discovered by Edward Jenner, physician of England, born in 1749. If we unfold history of vaccination preceding Edward Jenner, there was scant practice of small pox inoculation but wasn’t established firmly. Edward Jenner successfully trialed the vaccine and founded a base for further discovery. However, the inspiration for this quest is quite interesting.

Loathsome Disease

Smallpox, a viral disease, which claimed many people usually due to compromised immunity, high grade fever, excessive oozing of blood and body fluids as the wound all over the body sloughed off and extreme pain, and left lifelong pock marks to the survivors. We can still find some aging survivors with small pox scars. I still remember recently deceased Indian actor Mr. Om Puri, who was able to survive small pox but left with scars.
William Foege, a physician from USA, a pioneer in small pox eradication, who worked relentlessly day and night in developing countries including Africa, Asia to eradicate Smallpox from the population, in his book “House on Fire, The Fight to eradicate smallpox” describes this disease as loathsome disease and he recollects how he was able to identify the cases just by smelling the putrid smell coming from the patients. He recalls how he spotted one of the cases of smallpox in his book,

“On at least two occasions, smell alone alerted me to the presence of smallpox. As I walked down a hospital hallway in India, the dead-animal odor stopped me in my tracks; following the smell, I located a smallpox patient.”

And he further describes its severity as

“ In another house a young man might be wearing only a loincloth, because he didn't want anything touching his face or limbs, which were covered with lesions. His legs were bloody. He was trying not to move, grimacing in pain when he did. Any touch caused the lesion to bleed. His face was contorted with pain; he wanted only to die.”

The Inspiration of Vaccine discovery

Edward Jenner in his early phase of career, he observed that many of the villagers were infected with smallpox and had pockmarked faces but the milkmaids. He observed that many milkmaids were fairer though people contracted diseases and left some survivors with the lifelong pockmarked scars and of course, immunized. He overheard milkmaid saying she would never get such pockmarked face, and she won’t contract small pox as she already got cowpox, which makes her invulnerable to smallpox. Influenced by those experiences and evidences, after 12 years of continuous observation and record keeping, Edward Jenner implemented the inoculation with cowpox for the first time in a child named James Phipps, and as his expectation, the child developed immunity against smallpox when later exposed to smallpox virus.
This first experiment engenders the principle of vaccination and beginning of smallpox eradication and maybe a root of public health.

Though there were many people before him, who practiced the inoculation or many just like William Foegoe who continued his endeavor as a physician, public health actor or care giver after him but he is definitely a pioneer who sow the seed to reap the fruits that swept away existence of nasty small pox virus. His scientific experiment, anecdotes founded the base of greatest invention of all the time.

Inspiring Attributes to adopt

We are faced with many diseases or challenges, or everyday situations that pose constant threat to our health and we might be neglecting the remedies that exist around us. The observation skill and bringing the observation into thinking is important first step. Edward Jenner's keen observation and conviction about relation of immunity of milkmaid with cowpox infection resulted in this greatest boon to mankind. Aside from the scientific knowledge, perseverance, and risk taking to give one's thought a chance routed to the discovery of the principles of vaccination and essential action of public health.
Every time I read this history I find its message more meaningful!

HPV vaccination: Primary prevention of cervical cancer

HPV vaccines

Human Papilloma vaccine (HPV) is a unique vaccine as this is intended against the virus amidst many available vaccines that are produced against bacteria. HPV, in abbreviated form, is given to develop immunity against the Human Papilloma virus. Available HPV vaccines are recombinant vaccines, which include genetically engineered HPV like virus particles.
Two doses of HPV vaccines at 6 months’ interval is recommended for girls of age 9 to 13 years by WHO. The age of the girls is specified to make sure that the girls get this vaccine before they contract HPV viruses by any means or sexual transmission.

Currently Available HPV vaccines

Ceravix : Effective against HPV STRAINS of 16, 18

Quadrivalent Gardasil: This is effective against HPV strains of 6,11, 16, 18

Gardasil 9: This includes antigens against 9 different strains of Human Papillomaviruses

All of these HPV vaccines are given intramuscularly.

Cervical cancer, caused by HPV, is one of the commonest cancers in women of developing countries. Thanks to human intelligence, this life threatening malignancy can be prevented by comprehensive implementation of preventive approaches, one of them being HPV vaccination.

Human Papilloma Virus

Human Papilloma virus infection leads to a range of manifestations from some epithelial lesions, warts to life threatening malignancies. Though Papillomavirus can cause other ano-genital, oropharyngeal cancers, cervical cancer has been extensively studied in relation to Human Papilloma virus because of its high magnitude among women especially in developing regions.
Most of the cancers of anal, oropharyngeal, cervix, are caused by human papilloma virus infection. These cancers are preventable if we could prevent and manage Human Papilloma Viruses infection.

Which Human Papilloma virus is responsible for cervical Cancer?

There are different strains of Human Papilloma viruses, however, mainly the strains HPV 16, 18 are attributed to cause cervical cancer. They can also cause premalignant genital lesions and other many strains cause genital warts, lesions of cervix, vulva, vagina.

What makes Nepalese women more vulnerable to HPV infection?

HPV infects not only women, rather it can affect both male too. However, the prevalence of high cervical cancers and susceptibility of women demands solemn attention.

Low awareness on HPV: women of this generation hardly knew about the relation of infection with human papillomavirus and cervical cancer. This lack of awareness prevented us from taking measures that would have helped in management of HPV infection. Nevertheless, upcoming new generation will be more aware and have means to prevent HPV infection

Reproductive health, hygiene and rights: Early marriage, sexual violence can lead to exposure to HPV viruses. Reproductive health especially sexual health is not much talked issue in developing countries due to stigma, hesitancy, and traditional mindsets. Sexual problems are like the iceberg in the sea, much of large chunk still under sea as people don’t want to expose about reproductive health problems and people are shielded from the right information on reproductive health.

HPV vaccination in Nepal

Government of Nepal has forwarded this important step with piloting of HPV vaccinations with support from GAVI alliance. This will be scaled up subsequently nationally. this vaccine is relatively novel and expensive vaccine. Hence, the feasibility of the sustainable inclusion in the national immunization program requires strong commitment from the government and generosity of the donors and International organizations.
Other primary preventive approaches such as sexuality education to both girls and boys, male circumcision, condom use, health information and warnings about tobacco use should be implemented effectively to curtail the cervical cancer burden.

“मेरो बर्ष २०७४: म स्वस्थ, मेरो देश स्वस्थ”

Healthy Year 2074: A New Start in Nepal's Health System

This is a promising start from health minister Mr. Gagan Thapa in Nepalese Public health sector. It triggered many of us; It impressed many forerunners in health profession. Indeed, we need something, be it some goals, deadlines or slogans to keep us moving. Let’s remember, we are so much driven by millennium development goals and sustainable development goals to meet their targets. So, this new campaign of “My Year 2074: I am Healthy, My country is healthy” (this is my unofficial translation of the slogan) will surely motivate us to remain committed for keeping ourselves and our people healthy.


Our health system was quite sensitive towards tobacco related products but the alcohol drinking was overlooked issue and this commitment is expected to aware people of harmful effects of alcohol resulting reduced consumption. Our country is being rapidly urbanized and many of us live sedentary lives in a chair so the slogan of remaining physically active will surely benefits many of us, who are living sedentary lives.

Another slogan refers to appropriate and right consumption of locally available healthy and balanced diet. As we say, ‘We are what we eat’, this will encourage us in supplementing the diet required for growth and development and regeneration of people in every age group. Regular health checkup screens diseases in its early phases making primordial, and primary prevention enough. This further reduces cost of individual and the health system. The fifth slogan tries to accommodate all the health issues related to family planning, child bearing and rearing, neonates, infants and children and old age people.

Some addition in set of commitments

If we critically see the slogans of this campaign, it is much oriented towards preventing the non-communicable diseases. It has proactively attempted to capture the transition of our communicable disease burden to non-communicable diseases. But, we still have pre-existing conditions that trigger the transmission of communicable diseases such as lack of improved sanitation and safe drinking water. This bothers us many of public health professionals including me, much than remaining physically active. Though, we have come in the 21st century, only the time passed, we are still far behind.
In some parts of the country, people live the lifestyle of early twentieth century and some live like in 21st century. Because of this vast differences in life styles, living standards, awareness level, I seriously want to include the components of waste management, personal hygiene, sanitation facilities, clean city and improved housing, improved drinking water in this slogan. Let’s quit the use of tobacco product and alcohol drinking; Let’s remain physically active; Let’s have healthy and balanced diet; Let’s perform regular health check up; Let’s spread awareness on Family and community health issues.

“My commitment to My Year 2074”


  • I will Commit to following points in Year 2074 and onwards..
      I will quit the use of tobacco product and alcohol drinking.
      I will remain physically active.
      I will have healthy and balanced diet.
      I will perform regular health check up.
      I will remain aware of Family and community health.

    Yes,

      I will keep personal hygiene.
      I will keep my house and city clean.
      I will have improved sanitation and safe drinking water.

    Vaccines Types and Storage

    Type of vaccines

    Currently available vaccines protect us from diseases caused by selective pathogens: bacteria and virus. Vaccines are usually categorized based on the constituents of the vaccines.

    1. Inactivated/ killed vaccine: Those vaccines containing killed pathogens or particles are killed/Inactivated vaccines. Even though they are killed, they can trigger immune reactions, hence protects from the targeted diseases in the future. e.g. IPV

    2. Live Vaccines: Vaccines consisting of live strain of pathogens are live vaccines, however, they are attenuated or weakened to reduce their virulence or infectivity. They are not capable enough to cause disease but triggers immune response for future protection.

    3. Toxoid vaccines: Some of the disease conditions are caused by toxins produced by the microorganisms rather than pathogens themselves. Eg. The symptoms of tetanus is caused by the toxins such as tetanspasmin, produced by the clostridium tetani. Those toxoid vaccines contain the treated toxins of the disease causing pathogens which trigger the immune system to produce antitoxins.

    4. Subunit and Conjugate vaccines: Subunit and Conjugate vaccines contain only the certain components of the pathogens, for example vaccine against Hepatitis B virus contains antigens (protein structure) of the hepatitis b virus that incite the immune reactions against Hepatitis B virus. Some Subunit vaccines are produced with genetic engineering. Conjugate vaccines are unique and effectively powerful as the part of the pathogens are combined with carrier protein making them more effective.

    Vaccine Types and Storage
    Vaccine Targeted disease Form Type Storage
    Bacillus Calmatte Guerin (BCG) Tuberculosis Lyophilized powder , multi dose vial, requires reconstitution with diluent Live attenuated ( They are live but weakened to reduce their infectivity or virulence) 2 to 8 °C (As this is freeze-dried, hence recommended to store at -20C but no longer recommended)
    DPT-HB-HIB Diphtheria, Pertussis,Tetanus, Haemophilus influenza, Hepatitis B Liquid, multi-dose vial Combination of diphtheria toxoid, inactivated pertussis, tetanus toxoid, Antigen (HBsAg) 2 to 8 °C (Don’t freeze)
    OPV Polio Liquid, multi-dose vial Live attenuated vaccine Should be frozen at -14 °C in primary vaccine center but could be stored at 2 to 8 °C
    IPV Polio Liquid, single dose vial/ multi-dose vial Inactivated vaccine store at 2 to 8 °C, don't freeze
    Pneumococcal conjugate vaccine (PCV) Diseases caused by Streptococcus Pneumoniae Clear Liquid Suspension Conjugate vaccine store at 2 to 8 °C
    MR (Measles-Rubella) Measles and Rubella Lyophilized powder, Requires reconstitution Live attenuated store at 2 to 8 °C
    JE (Japanese Encephalitis)Vaccine Japanese Encephalitis Lyophilized powder, requires reconstitution, single-dose vial/ multi-dose vial Live attenuated (Chengdu SA-14-14-2 strain) store at 2 to 8 °C, should be used within 30 minutes of reconstitution
    Td (Tetanus, diphtheria) Vaccine Tetanus and Diphtheria Liquid suspension Toxoid Vaccine store at 2 to 8 °C

    BCG

    BCG is the abbreviated form of Bacillus Calmette Guerin. This vaccine is given for developing immunity against tuberculosis. In this vaccine, the strain of tuberculosis bacteria is live and attenuated, hence they are harmless and doesn’t cause disease but are active enough to induce immune reactions. This produces necessary antibodies and memory cells to protect against future potential tuberculosis infection.

    DPT-HB-Hib

    DPT stands for diphtheria, pertussis, tetanus. Previously, DPT vaccine contained only the antigens for DPT that protects against diseases, diphtheria (known as “Bhyagute rog” in Nepali), pertussis (known as “Lahare khoki” in Nepali), tetanus (known as “Dhanustankar” in Nepali). However, the vaccine is now pentavalent and protects the five diseases including Haemophilus influenza type b and Hepatitis B. Haemophilus influenzae is one of the common causes of the pneumonia in children in Nepal. It can also cause ear infections, meningitis.

    Polio vaccines

    There are two types of polio vaccines: Oral polio vaccine (OPV) and Inactivated polio vaccine (IPV). Inactivated (Killed) polio vaccine (IPV), containing killed pathogens, is developed by Dr. Jonas Salk. Albert Sabin is the developer of non-killed i.e. live oral polio vaccine which contains strains of weakened live polio viruses. When I had confusion regarding name of developers of live and killed vaccines, I used to remember by the work ‘k’ in Salk so he is the developer of killed polio vaccine and IPV is given by intramuscular route whereas live vaccine is administered by oral route.

    MR vaccine

    MR stands for measles and rubella. Previously, only measles vaccine was given to the Nepalese children. Later, Rubella has also been added to the EPI schedule of Nepal and MR vaccine is given subcutaneously at the age of nine months. MR vaccines protects children from diseases Measles and Rubella.

    Pneumococcal vaccine

    Pneumococcal vaccine is given to develop immunity against infection of streptococcus Pneumoniae.

    Td Vaccine

    Recently, Td Vaccine is prescribed to prenatal mother in Nepal. Td stands for Tetanus and the diphtheria. This vaccine contains chemically treated toxoids of tetanus and diphtheria that triggers the immune system to prepare for future potential toxin exposure.

    JE vaccine

    JE vaccine is given against the Japanese encephalitis. Japanese encephalitis is a mosquito borne (spread by mosquito bite) viral disease caused by infection of JE virus. Live JE vaccine is given in Nepal at the age of 12 months

    It is always essential to check the manufacturer’s guide about storage and transport. Even though all the vaccines provide some level of protection against specific diseases, they are not free of adverse reactions so, it’s very important to inform vaccine recipients of all the anticipated adverse reactions. Here in my experience in USA, when I had to take the vaccines for compliance of vaccination as recommended by the university, I was given pamphlets related to vaccines and its adverse reactions and consented for the vaccinations and their unwanted reactions (a part of defensive medicine.).

    Alcohol: A Neglected Threat

    Factors affecting Alcohol Use in our society

    • In modern contemperory society!
      “We finished the exam. Let’s have a party!” a friend exclaims,
      “No Alcohol!” another friend exclaims,
      “Is that a party?” other friend yells,
      “Hey, just taste it. You’ll love it, a peg of alcohol is good for your health; you’ll not suffer from heart attack.”
      Other friend gives rationale, “You’ll forget all your pain at least for a while, it relaxes your mind.” the friend encourages,
    • In a traditional society!
      “It’s our culture, you need to drink it; It is sacred offering to our god and it's a Prasad from god.”
      “Your ancestor used to drink it, we drink and you can drink.”
      “Please, have some alcohol (the form could vary). You must be tired and hungry.”
      “When did you start drinking?”
      “I don’t remember at all, I used to drink since the day I know my existence”
      Those conversations clearly demonstrate the role of cultural practice, inadequate scientific knowledge, ignorance, peer pressure, adventure seeking habit in starting alcohol use.

    Magnitude of Alcohol Use: Epidemic or Endemic?

    The alcohol is one of the commonly used substances in our society but it is not tabooed or stigmatized like other substances such as heroin, opium at least in our society. Instead, alcohol has become an integral part of our culture. The alcohol use is pervasive in every society. Its use is highly contagious and endemic (not an infectious agent but the extent of its prevalence and incidence) especially among certain group of people in Nepal. "I recall my conversation with one of my students. He was a member of national level research on non-communicable diseases, he was astonished to see the people intoxicated with alcohol even during day time and they were even frightened to conduct interview itself in Dhankuta district, Nepal, where the majority belong to Matwali (Rai, Limbu, Magar, Yakkha) group (Population Monograph of Nepal, 2014)."
    Belonging to an indigenous group that allow alcohol use and uses alcohol for sacred rituals, it is usual for me to see people, who used alcohol mildly, moderately to heavily. I saw many died with gastric bleeding, which was usually blamed for some witchcraft or god’s wrath sometimes. As the limited amount of alcohol has been further idolized as cardio-protective drink by modern science, this has been a most abused reasoning for the alcohol users lately.

    Effect of Alcohol Use on Health

    Physical Health: Many researches have accorded that alcohol can shrink the brain mass with regular and occasional heavy doses. It can cause alcohol related brain damage and dementia can occur as early as at the age of 40 to 50. Alcohol is metabolized in Liver so It also affects liver leading to Alcoholic liver diseases including Cirrhosis. Cirrhosis causes irreversible damage to liver cells and diminish the liver function. As it affects the liver, it can also lead to portal hypertension and further causing gastric bleeding. Many people die of untimely management of gastric bleeding. It also affects all other parts of the body. Heavy and regular drinkers also suffer from decrease in libido and other reproductive system dysfunction. Alcohol related cancers in esophagus, stomach, liver are also contributors of mortality and morbidity. Alcohol kills not only by deteriorating health of the people, it also causes mortality, disability and morbidity indirectly by road traffic accidents, homicides, injuries, violence.
    Psychological Health: Just like other substances, alcohol causes physical and psychological dependency and its tolerance accelerates the amount of alcohol as the increased amount of alcohol is required to get the same level of effect. The alcohol becomes an eye opener for the alcohol-dependent people.
    Social Impact: Alcohol overuse also impairs the family and social relationship. Even though occasional and scant drinking can be a mean of social interaction, the excessive use of alcohol brings strain in family as the uninhibited, incomprehensive, ineffective and offensive communication may prevail.
    Economic Impact: Alcohol use directly impacts the economic status of the person by draining resources to purchase alcohol; those resources could have been used in other useful purposes such as nutrition, education, recreation of the family. Alcohol use can also affect the economic status of the family by reducing the working capacity and performance of the person.
    Some beneficial effects of alcohol have been reported by researches especially congestive heart failure and diabetes mellitus but the negative effects offset the probable beneficial effects of it.

    Control Measures

    Formulation of laws and implementation: Strict implementation of National Alcohol Regulation and Control Policy - 2017 can successfully decrease the alcohol use. This policy reform increased the legal drinking age to 21 from 18, which is highly praiseworthy. Statutory and pictorial warning should be displayed in the alcohol containers. Just like control measures for smoking, the same graphic and text warnings encourage quitting of alcohol in alcohol users and discourage others to try alcohol. The policy has also bans the use of alcoholic beverages in public parties hosted by government institutions. This policy also bars of any form of advertisement about alcoholic beverages. Alcohols are restricted to sell in public places such as schools/colleges. The concept of dry days should also be added in the current policy as people are more likely to drink alcohol in certain occasions as in festivals.

    Awareness Programs: Education is the key to success of any health programs. Education is aimed to impart the knowledge to modify the behavior and shape the perception about particular things. Substance abuse is manifestation of a behavior that can be modified by modification of existing knowledge. Awareness about negative impacts of alcohol will help in decrease in demand. Homemade alcohol is easy to find almost everywhere in the neighborhood of Nepalese community that can be overlooked by the existing laws making awareness programs more indispensable. Similarly, those neighborhoods whose economy depends on homemade alcohol should be provided with alternative vocational trainings and financing opportunities. Early education with integration in curriculum of schools can also be effective in shaping the attitudes of the future generation.
    It is very essential to direct such awareness programs and other interventions to the most needy populations where the alcohol use is mostly concentrated such as aforementioned ethnic groups, rural area, community with low socio-economic status.

    Top Ten Public Health Issues in Nepal

    1. Childhood Diseases

    Childhood diseases including diarrheal and acute respiratory diseases: The seasonal diarrheal diseases and respiratory diseases affect substantial number of children in Nepal leading to deaths and developmental delays. The malnourished and undernourished children are equally prevalent and Hence childhood diseases are still the number one priority in public health in Nepal. Neonatal mortality rate (21 per 1000), infant mortality rate (32 per 1000) and under 5 mortality rate (39 per 1000), are still high enough making it number one public health problem in Nepal.

    2. Water and Sanitation

    The timeline of health and longevity of the people in the developed countries can be traced back to sanitary reforms in those countries and the resulting long life expectancy and healthy life can be attributed to the adequate supply of potable water, appropriate sanitary facilities, waste management. However, Nepal and other developing countries are miles away to reach that level as the waste management and other sanitary reforms are at nascent phase, though progressive. There are 38% of households without improved sanitary facilities in Nepal.

    3. Maternal and perinatal health problems

    Still women in Nepal die during pregnancy and childbirth due to untimely management of complications such as antepartum hemorrhage, postpartum hemorrhage, pre-eclampsia, eclampsia. This is especially intensified by lack of adequate facilities and manpower in rural area of the country. Even though the tertiary level care facilities are available in major cities, many parts of the countries are devoid of such care and it takes several hours or days to reach to such care resulting in delays in care, subsequently fatal consequences to many women and children.

    4. Sexual transmitted diseases and Other communicable diseases

    Tuberculosis is endemic in Nepal. Vector borne diseases such as malaria, Leishmaniasis (Kala-azar), Dengue, are also endemic in certain tropical regions (plains) of the Nepal. sexually transmitted disease such as HIV/AIDS is present as concentrated epidemic in certain groups such as sex workers, intravenous drug users, migrant workers, wives of migrant workers.


    5. Epidemics/Pandemics and zoonotic diseases

    Every country is at risk of pandemics and epidemics due to increasing interconnectedness between different parts of the world/ globalization. Most of the pandemics are the zoonotic diseases; they contract human easily as they are novel and human are susceptible due to their inability to fight against new diseases as they lack antibodies and memory cells against such diseases. The recent phenomena of unregulated mass production of poultry and close living provision with the animals also leads to the zoonotic diseases.

    6. Non-communicable diseases

    The occurrence of the non-communicable diseases such as hypertension, coronary heart diseases and other cardiovascular diseases, diabetes mellitus, chronic kidney diseases have surged along with modernization in life style. They are leading reasons of mortality and burden of diseases. Epidemiologic transition is evident through increased incidence of non-communicable diseases, once supposedly diseases of wealthy.

    7. Natural disaster and preparedness

    Nepal is continuously at risk of natural disaster due to its topographical/geographical features. Nepal is at constant threat of earthquakes as this lies in the Himalayan range; the floods during the rainy seasons pose equal threat to the lives of the residents of Hills and plain. The massive earthquake in 2015, the frequent landslides and yearly floods in the major rivers of Nepal create a chaotic condition that requires immediate attention of every sectors including public health professionals. As people in such situations are at risk of so many health problems such as injuries, diarrheal disease epidemic, devoid of water and sanitation, food and security, they require immediate first aid, safe sanitation and water facilities, food, security, reproductive health services and mental health counselling and management. Disaster preparedness and effective communication channel are must have public health program in Nepal.

    8. Substance use disorders

    Drinking alcohol is a ritual by a certain group of people specifically indigenous groups traditionally categorized as ‘Matwalis’ of Nepal, includes Rai, Limbu, Newar, Gurung etc. Alcoholic dependence and liver diseases are very common in those people though they are under-focused by the current health system. Alcohol dependence not only affect the health of the sufferer, it also affects the social relationship, economy and family relationship. Tobacco use is also a common substance and its use is ubiquitous in the form of smoking, chewing form in Nepal; shisha hookah is established as recent trend among youth. Other substances like Marijuana, Heroine are also threatening public health concern to the youth of Nepal.

    9. Disparity in Health system

    This is a significant challenge that needs immediate attention from the government. Though the number of hospitals and number of health professionals are increased significantly in last two decades, people from the rural area and poor of urban areas don’t have adequate access to health care. Disparity in health care access is affected by different elements ranging from individual attributes such as ignorance fueled by low education, low income; to systematic biases created by the system and policies.

    10. Mental health Problems

    Mental health needs of the populations is recently recognized as vital after the decades of neglect in mental health domain. Mental health problems were accepted as the result of bad deeds in previous or present life, hence stigmatized. Professional growth and advocacies have highlighted the need of mental health treatment and management. The years long political conflicts, low economy, disasters, increasing social distances, individualistic life approach, high pressure for achievement, rapid urbanization, employment abroad etc. aggravate the mental health need of the population.

    Quality Of Life

    Quality of life is one of the important indicators to measure overall population health or health status of the people living in any location. As the end expected outcome of any medical intervention, nursing intervention or any public health program is to improve the quality of life, health professionals at least once think about measuring Quality of life among their population of interest in their professional life.

    What is quality of life?

    Quality of life is a multidimensional concept and it involves subjective evaluations of various aspects of life. Human life has complicated structure physically and socially, as human can’t exist alone. They have body, which is further controlled by the mind, their mind is further affected their social, physical surrounding, system and significant others. Thus, quality of life is very difficult to measure. However, experts have developed definitions and tools to measure the quality of life of people.

    WHO defines quality of life as “individuals’ perception of their position in life in the context of the culture and value systems in which they live and in relation to their goals, expectations, standards and concerns.”

    Why do we use quality of life?

    1. Comparison of people in different geographical region: people in different geographical area can be compared with this indicator. It will be easy to understand the reasons for the differences in Quality of life in those geographical region. Why do Swiss have better quality of life than Chinese or other countries?
    2. Impact of any program or intervention or Policy: Quality of life indicator is the ultimate outcome of any interventions. The aim of smoking control and prevention program could be to reduce the number of people, who smoke, its effect could be seen as the change in quality of life in the targeted population. The improvement in relationship, self-esteem, improvement in physical health, improvement in environment, reduction in expenditure increases the quality of life of the people through the smoking prevention policies and programs. Depending on assessment of the quality of life, the policy, programs or interventions could be designed and modified so that they increase the quality of life of targeted population.
    3. Health needs: Need of the population could be evaluated with this indicator. Lower quality of life indicates lack of good health or failings in other parameters and ultimately the shortcomings in the existing programs, and inadequate interventions to improve the quality of life.
    4. Effect of chronic illness, short term or long term illness: We can also estimate impact of certain disease conditions on quality of life and to measure the ways to improve quality of life of the people living with such disease conditions.

    Tools to measure the quality of life

    • CDC HRQOL-4: Centre for disease control and prevention (CDC) uses 4 items questionnaire CDC HRQOL-4.
    • CDC HRQOL-14 “Healthy days measure”: This is constructed by adding 10 more items in CDC HRQOL-4 tool.
    • WHOQOL-100: This tool is developed by world health organization and it is elaborate. This includes 100 questionnaires from different aspects of life, that can affect the quality of life of a person.
    • WHOQOL-BREF: It is abbreviated form of WHOQOL-100 and consists of 26 items only.

    There are some tools such as SF 36, SF 12, which can be used to measure Health status of any population. They also used as quality of life indicators sometimes by some authors.

    Difference between CDC Health related quality of life (HRQOL) and WHOQOL scale

    The definition of health includes mental, physical, social and spiritual domains of life and HRQOL should measure all aspects of those domains. HRQOL tends to measure the quality of life that are directly related to health status of the people. HRQOL tool used by CDC contains items/ questions related to subjective perception of overall general health status, mental health, physical health and activity limitations. WHOQOL is more elaborate and includes health, psychology, level of independence, social relations, environment, spirituality/ religion/personal beliefs. WHOQOL-BREF is usually used in small scale studies. Authors need permission to use WHOQOL tools and required to abide by user agreement and researchers need approval if any modifications of the tool is required. WHOQOL have been adapted for certain diseases, for example, WHOQOL-HIV is constructed especially to assess quality of life of people with HIV.

    Nutritional status of children and Anthropometric measurement!!


    Background

    Nutrition is key to life. “In fact people are pack of nutrients and they need all the nutrition since the formation of embryo to become a mature human. They need nutrition to keep on restoring depleted nutrition throughout the life.” This makes maternal, childhood, adult nutrition equally important throughout the life course of human.

    How does Nutrition affect the Health?

    If you don’t get adequate and essential nutrients, physical and mental growth will be delayed through various mechanisms, causes many diseases and even leads to death. The foremost mechanism is direct nutritional deficiency diseases such as deficiency of Vitamin A causes night blindness; imbalance of protein and carbohydrate results in PEM malnutrition, obesity; Iodine deficiency causes mental retardation, goiter. There are number of disease conditions that are directly related to the nutrition deficiencies. Such diseases are also responsible for other chronic disease such as cardiovascular diseases, diabetes.

    Figure: Factors affecting Nutrition and its impact on health

    Lack of nutrition also reduces immunity thereby making our body susceptible to many opportunistic infectious microorganisms. As for example, in a healthy people, tuberculosis could be in dormant phase but once the immunity or defense system of our body is disturbed, TB pathogen can become active and manifest TB disease. Viral infections are especially immunity relative and immunocompromised people suffer bouts of seasonal influenza or diarrheal diseases compared to people with strong immunity.

    Anthropometric measures to measure the nutritional status of children

    Anthropometry is the study of measurement of body parts. Nutritional status can be measured by various indicators such as mid arm circumference, BMI, height for age, weight for height, weight for age etc. However, the last three aforementioned indicators are used frequently.
    Height for age: children should have comparable height for their age just like other children in their age group. If their height is below two standard deviations of that age group, then it is considered less height for age showing inadequate nutritional status. Having short gesture for age is also known as stunting. stunting is usually taken as sign of long term, chronic nutritional deprivation
    Weight for height : Having short gesture or height for weight is also known as wasting. wasted children have short gesture for weight.If their weight for height is below two standard deviations of that age group, then it is considered less weight for height showing inadequate nutritional status. Low weight for height is an indicator of acute undernutrition
    Weight for age : Similarly, this is one of the commonest and easiest way to measure the nutritional status of the children. children should have comparable weight for their age just like other children in their age group. If their weight is below two standard deviations of that age group, then it is considered low weight for age showing inadequate nutritional status. This combines information about linear growth retardation and weight for height

    Indicators in NDHS Nepal Demographic and Health Survey 2016

    According to NDHS 2016, 36 % of the children are stunted or have short gesture for that age group, 10% of the children are wasted or have lower weight for height and 27% under five children are underweight or have weight low for their age. These show Progress from the early years.


    What are the reasons of Nutritional deficiency in Nepal?

    I would like to describe the causes of nutritional deficiencies based on socio-ecological model.

    • Policy: Certainly, Nepal is a developing country and significant fraction of people live under the poverty and very far from the light of development and education. The policy helps to shape the investment in different section of the programmes and population.
    • Society, organization and culture: The culture, tradition and some taboos prevalent in the society, and organization equally affects the nutritional level of the population. Certain tradition like early weaning of female child, taboos prohibiting some foods during pregnancies, gender discrepancy in nutrition etc affect the nutrition of the children.
    • Family level factors: socioeconomic status of the family, trade off of investment in other things vs nutrition also affects the family's importance in nutrition. This also depends upon the over all understanding of importance of nutrition.
    • Individual level factors: Education of parents, other family members, occupation, knowledge about the nutrients, balanced diet and preparation, handling of the foods also affect the nutrition of the children
    • International support: International support has tremendous influence over the policy and programmes and current programs like SUAAHARA project is funded by USAID. Many UNITED NATIONS organization have focussed in improving child nutrition in Nepal and all over the world affected by malnutrition.

    A Message to PHD Aspirants!!

    by Dr. Jamal Hisham Hashim


    After having completed a PhD degree myself, and having supervised, co-supervised and examined a number of PhD students over the years, I would like to offer some humble advice and pointers to those aspiring to pursue a PhD degree themselves. I find that many Malaysians misunderstood the purpose of getting a PhD degree and the commitments and sacrifices that it calls for.

    Why pursuing PHD is different than other degrees?

    A PhD is the highest academic and research degree from a university. I have seen both remarkable successes and disappointing failures amongst students pursuing this academic accolade. It takes more than just brain power to complete a PhD. A degree by research is very different from a degree by coursework. A course degree whether at the undergraduate or masters level is heavily structured. A student just have to be disciplined and rigorous in following this predetermined structure regimentally, without much creativity required from him or her. Of course, creativity is demanded from the student in completing assignments and projects but the demand is nothing close to what is required for a PhD degree. The most important prerequisites for pursuing a successful PhD program are passion, inquisitiveness, creativity, discipline, persistence, perseverance and meticulousness (or attention to detail). I did not mention intelligence not because it is not important, but because it is less important than the other attributes I mentioned. At least, it is in my book. Others may feel differently.

    A key ELEMENT to success PHD: Passion!!

    Of those many attributes, I consider passion the most important. Some students start out enthusiastically but loses steam halfway through or towards the end. They lack passion or the love of knowledge. Ever heard of the saying, "when the going gets tough, the tough gets going?" Success in a PhD is simply that. The harder it becomes, the harder you will strive. Sometimes, you do not see the light at the end of the tunnel but you still keep looking for it because you know it is there. When you love what you do, failure is not an option.

    A good reason!

    Some people do PhD for the wrong reasons. Some take up postgraduate because they could not secure a job after their first or second degree. Some do it because the jobs they have taken up require them to acquire a PhD, for e.g. an academic or a research post. This cannot be more wrong. You cannot force yourself to do a PhD. You must want to do it badly enough. You cannot force yourself to love something; you must love or want something bad enough to force yourself to get it.

    What to expect from your supervisor

    Your supervisor is your mentor, guide and consultant, not your teacher. He cannot teach you your PhD knowledge, you have to teach yourself through his guidance and wisdom. He is more your friend than he is your master. He does not dictate to you what you must do, he merely points you in the right direction. At the end of your PhD journey, you would have been more knowledgeable on the subject of your research than your supervisor. I have heard of students not being able to complete their PhD because they could not get along or see eye to eye with their supervisor. This is the worst scenario that can happen to you. If you do not have a supervisor you can work with, you will not get your PhD no matter how good you are or how hard you work. So, choose your supervisor well, not just the university you want to do your PhD in. Just a few months back, I met a doctoral graduate who told me that to be supervised by this one professor carries more prestige among his peers in the working world.

    Get along or work alone??

    The PhD is an academic journey. There will be failures but mainly successes along your way. You may encounter some foes but mainly friends in the same boat as yourself. It always help to be in a group of students to share both your setbacks and achievements. Working alone in a silo is the worst you can do to yourself. There are certain things you want to discuss with your fellow students that you cannot discuss with your supervisor; matters that are either academic or personal. A PhD degree needs sacrifices, especially when you are a family person; a wife, mother, husband or dad. Family is always important and should always be your priority. However, you and your family members must be willing to make sacrifices that are necessary. There can be no gain without pain. That is why when you finally get your PhD degree, your family members can even be happier and more proud of you than you yourself, because it is as much their accomplishment as it is yours. Their sacrifices must be duly appreciated.

    Is this your achievement?

    So what does it mean when you have a Dr. before your name? Does it mean that you are an expert on a certain subject matter? Hardly so, I think. It means that you are both a seeker as well as a generator of knowledge. It means that you have enriched the world and added on to the vast body of knowledge through your PhD contribution. The world has become a slightly better place from the knowledge that you have contributed through your PhD thesis and publications. The world now knows more on a subject than before you completed your PhD. Your work get referred and cited by other researchers in your field, as they absorb your new knowledge to generate new knowledge of their own.

    Your PhD is an end of your one journey that should be justified by its means. The research methodology, the analysis and the interpretation should justify the conclusion. The new knowledge must have been tested and challenged by your peers and rigorously defended by you. It is an accomplishment unequal by any other feat. Once you have obtained a well-deserved PhD degree, you become your own teacher as self-teaching becomes common practice. You are always curious and tends to read a lot, not just on your subject matter but on everything. You will find doing new things, exploring new frontiers and taking up new challenges more scintillating. In other words, it will change your life and your outlooks forever.

    I hope I have inspired some of you to pursue a PhD degree if what you read here is what you really want from a PhD. On the other hand, I hope I have also discouraged others who have a misconception of what a PhD degree entails, so that you will not go down the road of failure. A PhD is not for everybody. You may share this post if you think it would help people you know in deciding whether pursuing a PhD degree is the right path for them to take.

    Thanks to Prof. Jamal Hisham Hashim for agreeing to share his thoughts in this blog. Dr. Jamal Hisham Hashim is Professor of Environmental Health in United Nations University.

    Gender Selective Abortion

    Background

    The most recent invisible phenomenon of modern day world in reproductive health is Gender selective abortion. Abortion is spontaneous, unintended and unfortunate event for some people whereas sometimes abortion is induced due to various reasons, mostly preclude the probable danger to the life of pregnant women. Nevertheless, this advancement of safe abortion in medical field has been also used as the sex selection tool for the birth of desired offspring aborting fetus of undesired sex.

    This phenomenon has been observed especially in those countries, where the patriarchy prevails and the birth is restricted by law or societal pressures. Even though profound effect of this phenomenon, the intensity of this problem is difficult to measure. Measuring female to male ratio at the time of birth is one of the indirect methods of the underlying gender selective abortion. Direct measurement of gender selective abortion is particularly challenging because of its ethical, moral, legal and social ground. The secrets are guarded and the population scientists are unable to measure the depth of this problem.

    The abortion policy in Nepal allows abortion up to 12 weeks of fetal age with the consent of pregnant woman unlike previous laws and only woman can decide whether to continue or discontinue the pregnancy. Although Nepal has engendered a very liberal abortion policy since 2002, to abort a fetus based on its sex is strictly illegal and considered criminal act in Nepal. So, many abortions might occur undercover. Hence, the indirect measurement of selective abortion such as sex ratio, population sex ratio, desired gender composition could be suitable tools to measure the gravity of sex selective abortion. Many researchers have figured out falling sex ratio at the time of birth as reflection of this phenomenon.

    Factors of gender preference and sex selective abortion

    Macro level Factors

    Here I would like to focus on certain Macro level factors of sex selective abortion.


    • Socio-Cultural dimension: Culture is important aspect of our life. We live and learn the culture from the day we are born. Similarly the perception that prefer sons over daughters has been passed down from one generation to another generation as an integral part of culture. Many of our countries in the world, the society is patriarchal and males are head of the households, they are the ones who forms social networking and maintains the boundary, integrity and function of the social net. Males are given higher position in that society and they are required for any ritual procedures during vital events like birth and death. I would like to particularly specify an example in Nepal. Couples are pressurized to have at least one son as they feel that if they are not given funeral pyre by their son, they wouldn't be able to go to heaven after life and daughters are not allowed to involve in such ritual. Though, many daughters have come forward to break this stereotype, It still is ingrained in minds of many people.
    • Economic Transition:Our traditional society was agrarian where the larger number of offsprings would be desirable assets to the family. Sons were valued the most because of their high physical strength and utility compared to daughters. Yet, they could be help to the household chores and strengthening the family relationships. There was negligent concept of child health and care so the number of offsprings was not an issue of high concerns but with human civilization and modernization, child care and the number of children in the family have been central focus of the family now. Higher number of offsprings have also been stigmatized as a sign of ignorance. High investment in child care, concern about the number of children and fixed attitude towards gender; son as must-have offspring have led the many men and women taking such decisions.
    • Technological advancement:Technological advancement has also been a contributing factor in sex selective abortion to some extent. Early detection of sex of the fetus with advanced ultrasonography and claimed safe abortion procedures serves to make decision for the trade for women health and the child of desired sex.
    • Demographic transition and Policy: As the population growth rate and the fertility rate were high, the government in China came up with the "One child policy". Similarly, the government led family health programs in Nepal came up with the slogans of two children . These official and unofficial government policies have also fueled the limitation of birth and consequently, gender selective abortion in invisible way.

    Pandemics!



    When there was outbreak of SARS, Ebola, H1N1 influenza, HIV and other certain diseases in the past such as Cholera, Plague (Black death), everyone all around the world were concerned about those diseases.  They spread over many countries in a short span of time, claiming many lives, causing anxiety, panics, terrors and sufferings. Whereas, there are other diseases, which are contained within certain geographic spaces. 

    The recall of HIV/AIDS Pandemic as a child in rural Nepal

    The first pandemic I became aware of was HIV/AIDS. After its spread from one country after another country, it also invaded the border of Nepal along with identification of the first case of HIV in 1988. HIV contracted one after another since then fueled by stigma, scarce knowledge about disease pathology, lack of management facilities. I have vivid image of my childhood where HIV was so stigmatized and people's perception about its mode of transmission: the illicit sexual act. When I was in middle school, it became more apparent due to its coverage in news and media, educational forums, debates. As I saw the epidemic rise of HIV/AIDS during my childhood, this childhood memory of HIV/AIDS as fear producing factor always relates to subsequent pandemics. 


    Conditions favoring Pandemics


    1. New antigens or infectious diseases: as people are not immune to new antigens or infectious diseases, there is possibility. Sometimes, the diseases are under researched or so new that we become unaware of its route of transmission. As in case of HIV/AIDS, at first it was thought it was transmitted among gay men only. It took several years to identify the modes of disease transmission.
    2. Antigenic shift
    3. Globalization: global diffusion of SARS traces back to the visit of a case (from Guangdong China) of SARS in Hong Kong in 2003 thereby spreading SARS to other people staying in the same hotel. Then the infectious agents of SARS travelled to different countries along with those people.
    4. Bioterrorism: Use of biological agents as a means of war can bring pandemics.

    Disease outbreak Vs Epidemic Vs Pandemic

    Disease outbreak occurs when the disease occurs in many people at a time more than expected at that point of time or more than usual occurrence. However, sometimes there shouldn’t necessarily be occurrence in large number of people, a single disease case is still considered outbreak. For example, one case of yellow fever in Nepal is considered outbreak/epidemic as there is no occurrence of yellow fever in the past. Public health professionals and the disease surveillance system should be effective enough to identify such outbreaks to tackle its spread and management in time. Outbreak is usually used to refer to a small geographical region.

    Epidemic: If the disease outbreak is concentrated in a certain geography or within certain communities and if there is no possibility of spread in other regions or countries, then it is called disease epidemic.


    Pandemic: When the disease spreads over several countries, continents or all around the world, usually affecting large number of people, this is termed as Pandemics.
