Question 83: What percentage of people living in developing countries lack access to basic sanitation facilities?

A. 70% are at risk of waterborne diseases
B. 60% have limited access to healthcare
C. 40-50% lack access to basic sanitation (Correct Answer)
D. 80% experience food insecurity

Explanation: ***40-50% lack access to basic sanitation*** - This option correctly identifies the percentage of people in developing countries who lack **basic sanitation facilities** according to WHO/UNICEF Joint Monitoring Programme data. - Lack of sanitation contributes significantly to the burden of **infectious diseases**, including diarrheal diseases, and overall poor health outcomes. - Improved sanitation is one of the key **Sustainable Development Goals (SDG 6)** targets. *80% experience food insecurity* - While **food insecurity** is a major issue in developing countries, this percentage is an **overestimation** of the global figure. - More importantly, this option addresses **food security** rather than **sanitation facilities**, making it incorrect for this question. *70% are at risk of waterborne diseases* - While many people are at risk of **waterborne diseases** due to poor water quality and sanitation, this option focuses on disease *risk* rather than the direct lack of **sanitation facilities**. - This does not accurately answer the specific question about access to basic sanitation. *60% have limited access to healthcare* - Limited access to **healthcare** is a significant problem in developing countries, but this option addresses *healthcare access* rather than **basic sanitation facilities**. - This percentage does not directly answer the question about sanitation infrastructure.

Question 84: What is the slogan of WHO for the year 2018?

A. Depression: Let's Talk
B. Health for All
C. Universal health coverage: everyone, everywhere. (Correct Answer)
D. Diabetes: Scale up prevention, strengthen care, and enhance surveillance

Explanation: ***Universal health coverage: everyone, everywhere.*** - This was the official theme for **World Health Day 2018**, marking WHO's 70th anniversary. - The theme emphasized the goal of achieving **universal health coverage (UHC)** globally, ensuring that everyone has access to quality essential health services without financial hardship. - It highlighted WHO's commitment to ensuring that at least **1 billion more people** benefit from UHC by 2023. *Health for All* - "Health for All" is the foundational vision established at the **Alma-Ata Declaration in 1978**, not a specific 2018 slogan. - This remains an overarching principle of WHO's mission but was not the designated theme for 2018. - While relevant to UHC discussions, it was not the official World Health Day 2018 theme. *Depression: Let's Talk* - This was the theme for **World Health Day 2017**, focusing on mental health awareness. - The campaign aimed to reduce stigma around depression and encourage people to seek help. - It emphasized that depression is a leading cause of disability worldwide. *Diabetes: Scale up prevention, strengthen care, and enhance surveillance* - This was related to the theme for **World Health Day 2016**: "Beat Diabetes." - The focus was on raising awareness about the rising burden of diabetes and the need for prevention and management strategies. - It called for strengthening diabetes surveillance and ensuring access to affordable treatment.

Question 85: Which of the following is the most significant international treaty specifically addressing tobacco control measures globally?

A. Paris Agreement
B. Kyoto Protocol
C. Framework Convention on Tobacco Control (Correct Answer)
D. Convention on Biological Diversity

Explanation: ***Framework Convention on Tobacco Control*** - The **WHO Framework Convention on Tobacco Control (FCTC)** is the first international public health treaty negotiated under the auspices of the WHO. It provides a comprehensive framework for tobacco control measures globally. - Its provisions range from **advertising bans** and **taxation** to **protection from secondhand smoke** and promotion of **cessation policies**, making it the most significant global effort against tobacco use. *Paris Agreement* - The **Paris Agreement** is a legally binding international treaty on **climate change**, aimed at limiting global warming. - It focuses on **reducing greenhouse gas emissions** and climate resilience, unrelated to tobacco cessation. *Kyoto Protocol* - The **Kyoto Protocol** is an international treaty that committed State Parties to **reduce greenhouse gas emissions**, based on the premise that global warming exists and human-made CO2 emissions have caused it. - Its focus is entirely on **environmental protection** and climate change mitigation, not tobacco control. *Convention on Biological Diversity* - The **Convention on Biological Diversity (CBD)** is a multilateral treaty with three main goals: the conservation of biological diversity, the sustainable use of its components, and the fair and equitable sharing of benefits arising from genetic resources. - This convention addresses **ecosystem health** and **biodiversity preservation**, which is distinct from public health interventions for tobacco cessation.

Question 86: An international health initiative aims to reduce the burden of malaria in sub-Saharan Africa. Which combination of strategies is most effective in achieving this goal?

A. Insecticide-treated bed nets and indoor residual spraying (Correct Answer)
B. Antimalarial drug distribution and public awareness campaigns
C. Improved sanitation and nutritional support
D. Vaccination and routine blood screenings

Explanation: ***Insecticide-treated bed nets and indoor residual spraying*** - **Insecticide-treated bed nets (ITNs)** provide a physical and chemical barrier against mosquitos while people sleep, significantly reducing transmission. - **Indoor residual spraying (IRS)** involves coating walls and other surfaces with insecticide, killing mosquitos that land on these surfaces and further reducing mosquito populations. - This combination represents the **WHO's primary vector control strategy** and has demonstrated the greatest impact on reducing malaria burden at the population level. *Antimalarial drug distribution and public awareness campaigns* - While **antimalarial drug distribution** is crucial for treating active infections and preventing severe disease, it does not directly prevent initial transmission from mosquitos. - **Public awareness campaigns** are important for educating communities, but without direct vector control measures, their impact on reducing overall burden is limited. *Improved sanitation and nutritional support* - **Improved sanitation** primarily impacts waterborne diseases and does not directly address mosquito-borne illnesses like malaria. - **Nutritional support** is vital for overall health and recovery but does not prevent malaria infection itself. *Vaccination and routine blood screenings* - While **WHO-recommended malaria vaccines** (RTS,S/AS01 and R21/Matrix-M) are now available and reduce severe disease in children, they provide partial protection (not complete immunity) and are most effective when combined with vector control measures. - **Routine blood screenings** are useful for surveillance and early detection but are not a primary strategy for preventing transmission at a population level. - This combination alone is less effective than the proven vector control approach of ITNs and IRS.

Question 87: In an international health study, researchers want to assess the impact of socioeconomic status on health outcomes. Which statistical method is best suited for this analysis?

A. Multivariate regression (Correct Answer)
B. Chi-square test
C. ANOVA
D. Survival analysis

Explanation: ***Multivariate regression*** - This method is ideal for examining the relationship between multiple independent variables (like **socioeconomic status** components such as income, education, occupation) and one or more dependent variables (various **health outcomes**). - It allows researchers to control for confounding factors and determine the independent contribution of each socioeconomic variable to health outcomes. *Chi-square test* - The Chi-square test is typically used to assess the association between **two categorical variables**, such as different socioeconomic categories and the presence or absence of a specific health condition. - It is not suitable for analyzing the impact of multiple continuous or ordinal socioeconomic factors on complex health outcomes. *ANOVA* - **ANOVA (Analysis of Variance)** is used to compare the means of a continuous dependent variable across **two or more groups** defined by a categorical independent variable. - While it could compare health outcomes between different socioeconomic *groups*, it is less efficient for modeling the continuous or complex relationships among multiple socioeconomic factors and health outcomes. *Survival analysis* - **Survival analysis** focuses on the time until an event occurs (e.g., time until disease onset, death, or recovery) and is often used in longitudinal studies. - While socioeconomic status can be a predictor in survival models, this method is not the primary choice for broadly assessing the overall impact of socioeconomic status on health outcomes in a cross-sectional or general population study.

Question 88: Which of the following conditions is the PRIMARY target for mass intervention under the WHO VISION 2020 initiative?

A. Diabetic macular edema
B. Refractive errors
C. Trachoma blindness
D. Cataract blindness (Correct Answer)

Explanation: ***Cataract blindness*** - **Cataract** is the **leading cause of blindness globally** (responsible for ~50% of world blindness) and the **primary target** of WHO VISION 2020 for mass intervention. - **Cataract surgery** is highly cost-effective, with proven outcomes, making it the cornerstone intervention for eliminating avoidable blindness. - VISION 2020 emphasized scaling up **cataract surgical services** as the most impactful strategy to reduce global blindness burden. *Trachoma blindness* - **Trachoma** was indeed one of the **five priority diseases** targeted by VISION 2020 through the **SAFE strategy** (Surgery, Antibiotics, Facial cleanliness, Environmental improvement). - However, cataract remains the **primary focus** due to its higher global prevalence and the immediate impact of surgical intervention. - Trachoma control requires long-term public health measures beyond just surgical intervention. *Refractive errors* - **Uncorrected refractive errors** were also one of the **five priority conditions** under VISION 2020, addressed through provision of spectacles and vision screening programs. - While important, refractive errors cause **visual impairment** rather than blindness, making them secondary to cataract in the elimination of blindness. - Management requires ongoing optical services rather than one-time curative surgery. *Diabetic macular edema* - **Diabetic macular edema (DME)** was **NOT** one of the five priority diseases under VISION 2020. - The five priorities were: **Cataract, Trachoma, Onchocerciasis, Childhood blindness, and Refractive errors**. - While diabetic retinopathy is increasingly important, it requires complex systemic management rather than simple surgical cure.

Question 89: Which of the following reflects a key health initiative promoted by the Colombo Plan?

A. Promoting cobalt therapy initiatives for cancer treatment
B. Strengthening human resources for healthcare (Correct Answer)
C. Establishing treatment facilities for various diseases
D. Support for diagnostic imaging technology in healthcare

Explanation: ***Strengthening human resources for healthcare*** - The Colombo Plan primarily focused on **technical cooperation** and **human resource development** in developing member countries - This included providing **fellowships** for training doctors, nurses, and other health professionals, and sending experts to assist in health education and infrastructure - The core mandate was **capacity building** through training and expertise, enabling countries to develop sustainable healthcare systems *Establishing treatment facilities for various diseases* - While improved health outcomes often lead to better facilities, the core mandate of the Colombo Plan was **capacity building** rather than direct construction or funding of treatment centers - The focus was on equipping local professionals to manage and develop their own health systems *Promoting cobalt therapy initiatives for cancer treatment* - While cancer treatment is crucial, cobalt therapy initiatives were not a primary or defining feature of the Colombo Plan's health strategy - The plan emphasized a broader approach to **healthcare infrastructure** and **human capital development** across multiple health domains *Support for diagnostic imaging technology in healthcare* - Support for specific technologies like diagnostic imaging was less prominent than the overarching goal of **human resource development** - The plan's emphasis was on foundational **training and expertise** across various health sectors rather than targeted equipment provision

Question 90: Which disease is most closely associated with intensive international surveillance for global eradication?

A. Polio (Correct Answer)
B. Hepatitis
C. TB
D. Leprosy

Explanation: **Polio** - **Polio** has been the focus of an intensive global eradication campaign, requiring robust **international surveillance** to track cases, mutations, and vaccine-derived polioviruses. - The **Global Polio Eradication Initiative (GPEI)**, a major international collaboration, relies heavily on coordinated surveillance efforts to ensure no wild poliovirus remains undetected. *Hepatitis* - While **hepatitis** is a significant global health burden, particularly hepatitis B and C, it is not subject to the same level of internationally coordinated, aggressive surveillance aimed at **global eradication** as polio. - Surveillance for hepatitis often focuses on prevalence, incidence, and risk factors at national and regional levels rather than a centralized, real-time eradication tracking system. *TB* - **Tuberculosis (TB)** is a major global health concern, and there are international efforts for control and elimination, but it is not currently targeted for **global eradication** in the same manner as polio. - Surveillance for TB often involves tracking drug-resistant strains and treatment outcomes, but it doesn't involve the immediate, outbreak-focused international alert system seen with diseases like polio or novel pandemics. *Leprosy* - **Leprosy** is a neglected tropical disease, and while there are international efforts for its control and elimination, primarily led by the WHO, it does not involve the same level of intensive, real-time global surveillance for eradication as **polio**. - Surveillance for leprosy is typically focused on case detection, treatment completion, and identifying areas with high endemicity rather than rapid international notification of individual cases for eradication purposes.
