Module 1: Foundations of Global Health
Foundations of Global Health
Knowledge check
Q1. Which of the following best defines global health?
- A. The study of diseases affecting only high-income countries
- B. An area of study and research that prioritizes improving health and achieving equity in health for all people worldwide ✓
- C. The practice of providing medical care exclusively in hospitals
- D. The regulation of pharmaceutical prices across national borders
Why: Global health emphasizes improving health and achieving health equity for all people worldwide, often addressing transnational issues that cross national boundaries.
Q2. What does the term 'health equity' refer to?
- A. Every person receiving identical medical treatment regardless of need
- B. The absence of avoidable, unfair, or remediable differences in health among population groups ✓
- C. Equal numbers of doctors in every country
- D. Government spending on health being identical across all nations
Why: Health equity means health differences that are unnecessary, avoidable, and unjust are minimized, recognizing that people should have a fair opportunity to be healthy.
Q3. Which organization is the United Nations agency that directs international health within the UN system?
- A. World Trade Organization
- B. World Bank
- C. World Health Organization ✓
- D. International Monetary Fund
Why: The World Health Organization (WHO), founded in 1948, is the UN specialized agency responsible for directing and coordinating international health matters.
Q4. What is the 'Global Burden of Disease' study used to measure?
- A. The total cost of hospitals worldwide
- B. The number of physicians per capita in each country
- C. The impact of diseases and injuries on populations, often using measures like disability-adjusted life years (DALYs) ✓
- D. The amount of foreign aid received by low-income countries
Why: The Global Burden of Disease study quantifies health loss from diseases, injuries, and risk factors, using metrics such as DALYs that combine years of life lost and years lived with disability.
Q5. Which term describes a health problem that crosses national borders and requires coordinated international response?
- A. Endemic disease
- B. Chronic condition
- C. Transnational health issue ✓
- D. Occupational hazard
Why: Transnational health issues, such as pandemics, antimicrobial resistance, and climate-related health risks, spread across borders and need collaborative global responses.
Module 2
Module 2: Infectious Disease Burden and Control
Infectious Disease Burden and Control
Knowledge check
Q1. Which infectious disease has historically caused the greatest number of deaths worldwide, primarily in sub-Saharan Africa?
- A. Measles
- B. Malaria ✓
- C. Smallpox
- D. Cholera
Why: Malaria, transmitted by Anopheles mosquitoes, has caused a very large global death toll, with the majority of deaths occurring among young children in sub-Saharan Africa.
Q2. What does the acronym DALY stand for in measuring disease burden?
- A. Disease-Adjusted Life Year
- B. Daily Average Lethality Yield
- C. Disability-Adjusted Life Year ✓
- D. Demographic Admission and Loss Index
Why: DALY stands for Disability-Adjusted Life Year, a metric combining years of life lost to premature death and years lived with disability to quantify total disease burden.
Q3. Which of the following is a primary reason vaccination programs have been effective in controlling infectious diseases?
- A. They cure infections once symptoms appear
- B. They build immunity in individuals and can create herd immunity across populations ✓
- C. They eliminate the need for clean water and sanitation
- D. They work only for diseases spread through food
Why: Vaccines train the immune system to recognize pathogens, protecting vaccinated individuals and, when coverage is high enough, reducing transmission to those who cannot be vaccinated.
Q4. Which organization leads global efforts to coordinate responses to infectious disease outbreaks and sets international health regulations?
- A. World Trade Organization
- B. World Bank
- C. World Health Organization ✓
- D. International Monetary Fund
Why: The World Health Organization coordinates international public health responses, including outbreak management, and administers the International Health Regulations.
Q5. What is the main reason antimicrobial resistance poses a growing global health challenge?
- A. Antibiotics are becoming more expensive to produce
- B. Microbes evolve so that drugs that once treated them become less effective ✓
- C. Patients are refusing to take medications
- D. Hospitals are no longer using antibiotics at all
Why: Through natural selection and genetic change, bacteria and other microbes can evolve resistance to drugs, making common infections harder and sometimes impossible to treat.
Module 3
Module 3: Maternal and Child Health
Maternal and Child Health
Knowledge check
Q1. Which of the following is considered the leading direct cause of maternal deaths worldwide?
- A. Obstructed labor
- B. Severe postpartum hemorrhage ✓
- C. Eclampsia
- D. Puerperal sepsis
Why: Severe postpartum hemorrhage, or excessive bleeding after childbirth, is responsible for roughly a quarter of maternal deaths worldwide. Most of these deaths can be prevented with timely uterotonic drugs, skilled care, and access to emergency obstetric services.
Q2. What is the primary purpose of antenatal care visits?
- A. To determine the sex of the fetus
- B. To monitor maternal and fetal health and detect complications early ✓
- C. To schedule the exact date of delivery
- D. To replace the need for skilled birth attendance
Why: Antenatal care allows health workers to monitor the mother and fetus, screen for conditions such as anemia, hypertension, and infections, and provide preventive interventions like iron supplementation and tetanus immunization. It complements, rather than replaces, skilled attendance at birth.
Q3. Which intervention has been shown to be most effective in reducing neonatal mortality in low-resource settings?
- A. Routine cesarean section for all births
- B. Skin-to-skin contact and exclusive breastfeeding initiated within the first hour of life ✓
- C. Early introduction of cow's milk
- D. Delaying bathing for several weeks
Why: Early skin-to-skin contact helps regulate newborn temperature, supports breastfeeding, and is linked to lower neonatal mortality. Initiating breastfeeding within the first hour is a low-cost intervention that substantially improves survival.
Q4. What does the term 'under-five mortality rate' measure?
- A. The number of children who die before their fifth birthday per 1,000 live births ✓
- B. The percentage of children under five who are vaccinated
- C. The number of children under five living in a household
- D. The proportion of children under five who attend school
Why: The under-five mortality rate is the probability of a child dying before reaching age five, expressed as deaths per 1,000 live births. It is a key indicator of child health and overall development in a population.
Q5. Which vaccine is commonly given to pregnant women in low-income countries to protect newborns from a deadly infection in the first weeks of life?
- A. Measles vaccine
- B. Tetanus toxoid vaccine ✓
- C. Polio vaccine
- D. Hepatitis B vaccine given only after age one
Why: Tetanus toxoid given to pregnant women helps prevent neonatal tetanus, a fatal infection that can enter through the umbilical stump when delivery or cord care is unhygienic. Maternal immunization has greatly reduced neonatal tetanus deaths.
Module 4
Module 4: Non-Communicable Diseases
Non-Communicable Diseases
Knowledge check
Q1. Which of the following is considered a non-communicable disease (NCD)?
- A. Malaria
- B. Type 2 diabetes ✓
- C. Tuberculosis
- D. Measles
Why: Non-communicable diseases are conditions that are not transmitted from person to person. Type 2 diabetes is a chronic metabolic disease driven largely by lifestyle and genetic factors, whereas malaria, tuberculosis, and measles are infectious diseases caused by pathogens.
Q2. What are the four main NCDs targeted by the United Nations' 2011 Political Declaration on NCDs?
- A. Cancer, diabetes, chronic respiratory diseases, and cardiovascular diseases ✓
- B. HIV/AIDS, malaria, tuberculosis, and hepatitis
- C. Obesity, depression, asthma, and arthritis
- D. Stroke, kidney disease, influenza, and anemia
Why: The 2011 UN High-Level Meeting on NCDs identified cardiovascular diseases, cancers, chronic respiratory diseases, and diabetes as the four major NCDs responsible for the largest share of premature deaths worldwide. The other options either name infectious diseases or include conditions not in this core group.
Q3. Which of the following is a major modifiable risk factor for most NCDs?
- A. Genetic inheritance alone
- B. Tobacco use ✓
- C. Age over 30
- D. Living in a rural area
Why: Tobacco use is one of the leading modifiable risk factors for cancer, cardiovascular disease, and chronic respiratory disease. Although genetics and age matter, the WHO identifies tobacco, unhealthy diet, physical inactivity, and harmful alcohol use as the key behavioral risk factors that can be changed.
Q4. Why are NCDs a growing global health challenge in low- and middle-income countries?
- A. These countries have no health systems at all
- B. Rapid urbanization, aging populations, and shifts toward processed diets increase NCD burden while health systems focus on infectious diseases ✓
- C. NCDs only affect wealthy populations in these countries
- D. NCDs are caused exclusively by poor sanitation
Why: Many low- and middle-income countries face a double burden: they still manage infectious diseases while NCD rates rise due to urbanization, longer life expectancy, and changing diets and lifestyles. Health systems designed around acute infectious care are often poorly equipped for long-term chronic disease management.
Q5. Which intervention is among the WHO's 'best buys' for reducing NCD mortality cost-effectively?
- A. Building new hospital wings for cancer surgery
- B. Raising tobacco taxes and prices ✓
- C. Importing expensive brand-name drugs only
- D. Expanding private specialist clinics in capital cities
Why: The WHO identifies tobacco tax increases, salt reduction, and tobacco advertising bans among its most cost-effective 'best buy' interventions. Tax policy is low-cost to implement and reduces consumption across the whole population, making it highly effective relative to expensive curative approaches.

Module 5: Health Systems and Financing
Health Systems and Financing
Knowledge check
Q1. What is the primary goal of a health system according to the World Health Organization's framework?
- A. To maximize profits for private healthcare providers
- B. To improve the health of the population in a way that is responsive and financially fair
- C. To eliminate all diseases within a single generation
- D. To centralize all medical research in wealthy countries
Q2. Which of the following is an example of out-of-pocket health expenditure?
- A. A government paying for a hospital building through taxes
- B. A patient paying a clinic directly for a consultation at the time of service
- C. An employer contributing to a worker's health insurance premium
- D. A donor agency funding a vaccination campaign
Q3. What does universal health coverage (UHC) aim to ensure?
- A. That every citizen receives free care only in private hospitals
- B. That all people can access needed health services without suffering financial hardship
- C. That governments spend the same amount on health as on defense
- D. That only people with employment receive medical treatment
Q4. Which financing mechanism pools funds from taxes or mandatory contributions to pay for health services?
- A. Direct out-of-pocket payment
- B. Social health insurance or tax-based financing
- C. Charitable fundraising alone
- D. Medical tourism
Q5. Why is a shortage of trained health workers considered a major challenge for health systems in low-income countries?
- A. Health workers are no longer needed due to advances in technology
- B. Limited numbers of workers reduce access to care and strain existing services
- C. Health workers in these countries are always overpaid
- D. Training programs have been shown to cost nothing
Module 6
Module 6: Environmental and Social Determinants
Environmental and Social Determinants
Knowledge check
Q1. Which of the following is considered a social determinant of health?
- A. Genetic predisposition to heart disease
- B. Access to education and literacy levels ✓
- C. Viral mutation rates
- D. Individual blood pressure readings
Why: Social determinants of health are the conditions in which people are born, grow, live, work, and age. Education and literacy shape health knowledge, employment opportunities, and income, all of which influence health outcomes. Genetic factors, viral mutation, and individual clinical measurements are biological or clinical factors rather than social conditions.
Q2. What is the term for the lack of safe drinking water, adequate sanitation, and hygiene that contributes to disease in many low-income regions?
- A. Water insecurity ✓
- B. Hydrological cycling
- C. Aquatic stagnation
- D. Osmotic imbalance
Why: Water insecurity describes limited access to sufficient, safe, and affordable water for drinking, sanitation, and hygiene. It is a major environmental determinant of diarrheal diseases, cholera, and other waterborne illnesses, particularly in low- and middle-income countries.
Q3. Air pollution from household cooking fuels such as wood, coal, and dung is most directly linked to which health outcome in low-income countries?
- A. Skin cancer
- B. Chronic obstructive pulmonary disease and acute respiratory infections ✓
- C. Type 1 diabetes
- D. Hearing loss
Why: Indoor air pollution from solid cooking fuels exposes millions, especially women and young children, to high levels of particulate matter. This is strongly associated with chronic obstructive pulmonary disease, pneumonia, and other acute respiratory infections, which are major causes of illness and death in low-income settings.
Q4. Which concept describes how a person's position in society, based on factors like income, education, and occupation, affects their health?
- A. Socioeconomic status ✓
- B. Epidemiological transition
- C. Herd immunity
- D. Biological ageing
Why: Socioeconomic status captures an individual's or household's economic and social position. Research consistently shows that people with lower socioeconomic status tend to have higher rates of illness and shorter life expectancy, due to differences in nutrition, housing, stress, and access to healthcare.
Q5. Climate change affects global health primarily by:
- A. Eliminating all infectious diseases
- B. Increasing the spread of vector-borne diseases and heat-related illness ✓
- C. Reducing the need for healthcare services
- D. Improving food security in all regions
Why: Rising temperatures and altered rainfall patterns expand the range of mosquitoes and other disease vectors, increasing malaria and dengue transmission. Extreme heat also causes heat-related illness and death, while droughts and floods threaten food and water security, creating further health risks.
Module 7
Module 7: Progress, Policy, and the Future of Global Health
Progress, Policy, and the Future of Global Health
Knowledge check
Q1. Which global health indicator is most commonly used to summarize a population's overall health and is defined as the number of years a newborn can expect to live in full health?
- A. Infant mortality rate
- B. Healthy life expectancy (HALE) ✓
- C. Gross domestic product per capita
- D. Crude birth rate
Why: Healthy life expectancy (HALE) adjusts life expectancy for years lived with disability or poor health, making it a useful summary of population health. Infant mortality, GDP per capita, and birth rate measure related but different aspects of health and development.
Q2. Which of the following is the best example of a global health policy success in the past several decades?
- A. The near-global eradication of smallpox ✓
- B. The complete elimination of malaria worldwide
- C. Universal access to antiretroviral therapy achieved in all countries
- D. The end of all infectious disease outbreaks
Why: Smallpox was declared eradicated in 1980 through a coordinated international vaccination campaign, a landmark success. Malaria and HIV remain active global challenges, and infectious outbreaks continue to occur.
Q3. What does the term 'Universal Health Coverage' (UHC) mean in global health policy?
- A. Every person receives free treatment for all diseases in private hospitals
- B. All people can access needed health services without suffering financial hardship ✓
- C. Every country adopts the same national health insurance model
- D. Vaccines are distributed equally by population size only
Why: UHC means all individuals and communities can use the health services they need, of sufficient quality, without facing financial hardship. It does not require a single model or free care for everything.
Q4. Which organization leads international coordination of health policy and sets global health standards?
- A. World Trade Organization
- B. World Health Organization ✓
- C. International Monetary Fund
- D. World Bank Group
Why: The World Health Organization is the United Nations agency responsible for directing international health work and setting global health standards. The WTO, IMF, and World Bank address trade, finance, and development, which affect health but are not primarily health authorities.
Q5. Why are the Sustainable Development Goals (SDGs) important for the future of global health?
- A. They are legally binding treaties that impose penalties on countries
- B. They link health to broader goals such as poverty reduction, education, and clean water ✓
- C. They focus exclusively on hospital construction in low-income countries
- D. They replaced all previous international health agreements
Why: The SDGs, adopted by the UN in 2015, recognize that health depends on many interrelated factors, including poverty, education, water, and gender equality. They are non-binding goals, not treaties, and they did not replace earlier agreements.
