Question 6: Which of the following is a true statement about screening tests for genetic diseases?

A. Screening test has better accuracy than diagnostic test
B. It is always invasive
C. It defines risk of transmission of disease to the child (Correct Answer)
D. Screening requires genetic mapping

Explanation: ***Correct: It defines risk of transmission of disease to the child*** - Genetic screening aims to identify individuals or couples at risk of passing on **heritable genetic conditions** to their offspring. - This information helps in **family planning** and provides prenatal diagnostic options if the risk is high. - This is the **primary purpose** of genetic screening programs. *Incorrect: Screening test has better accuracy than diagnostic test* - **Screening tests** are designed to be broad and detect potential risks, often with lower specificity and sensitivity than diagnostic tests. - **Diagnostic tests** are typically more accurate and definitive, confirming the presence or absence of a disease after a positive screening result. *Incorrect: It is always invasive* - Many genetic screening tests, such as **non-invasive prenatal screening (NIPS)** from maternal blood or carrier screening via saliva, are non-invasive or minimally invasive. - While some diagnostic tests like **amniocentesis** or **chorionic villus sampling** are invasive, screening itself is not universally so. *Incorrect: Screening requires genetic mapping* - **Genetic mapping** refers to determining the relative positions of genes on a chromosome, which is a research tool for understanding genome organization. - Genetic screening primarily involves testing for specific mutations or chromosomal abnormalities, not creating a comprehensive genetic map of an individual.

Question 7: Which of the following is the true statement regarding measures to prevent typhoid transmission in the community?

A. Typhoid vaccine administration is the best method of preventing transmission.
B. Person-to-person transmission is the primary mode of spread.
C. Drug resistance in typhoid is not as big a problem as in TB.
D. Hygiene practice and clean sanitation control are more important than the typhoid vaccine. (Correct Answer)

Explanation: ***Hygiene practice and clean sanitation control is more important than the typhoid vaccine.*** - **Improved sanitation**, safe water supplies, and adequate hygiene practices are fundamental in controlling the spread of **typhoid fever**, as the disease is primarily transmitted through the **oral-fecal route**. - While vaccines are an important tool, they offer only partial protection and must be combined with **robust public health infrastructure** and **sanitation measures** for effective prevention. *Typhoid vaccine administration is the best method of preventing transmission.* - Typhoid vaccines offer protection, but their effectiveness is not 100%, and they typically require **booster doses** - **Vaccination campaigns** are most effective when implemented alongside improvements in **water and sanitation infrastructure**, as vaccines alone cannot fully prevent transmission in areas with poor hygiene. *Person-to-person transmission is the primary mode of spread.* - While person-to-person transmission can occur, especially in settings with poor hygiene, the primary mode of spread for typhoid is through the **ingestion of food or water contaminated** with the feces of an infected person or carrier. - This emphasizes the crucial role of **water and food safety** rather than just focusing on direct person-to-person contact. *Drug resistance in typhoid is not as big a problem as in TB.* - **Antimicrobial resistance (AMR)** in typhoid fever, particularly to fluoroquinolones and extended-spectrum beta-lactamase (ESBL) producing strains, is a **significant and growing global health concern**, complicating treatment. - While TB also faces serious drug resistance issues, the escalating problem of **extensively drug-resistant (XDR)** and **multi-drug resistant (MDR)** typhoid strains makes it a substantial threat, impacting treatment options and increasing morbidity and mortality.

Question 8: A multivariate analysis was conducted to examine the relationship between risk of developing blindness and age. The results are shown in the table below. Which of the following is true?

A. 60-69 y age group shows statistically significant association with blindness
B. <50 y age group serves as the reference category
C. >80 y age group has the strongest association with blindness risk (Correct Answer)
D. 50-59 y age group has the highest odds ratio for blindness risk

Explanation: ***>80 y age group has the strongest association with blindness risk*** - The odds ratio for the **>80 years** age group is **2.1**, which is the highest among all age groups listed in the table, indicating the strongest association with blindness risk. - A higher odds ratio means a greater likelihood of the outcome (blindness) compared to the reference category. - All age groups shown have **p-values <0.001**, confirming statistical significance. *60-69 y age group shows statistically significant association with blindness* - While the 60-69 y age group has an odds ratio of **1.5** with **p<0.001**, indicating statistical significance, it does not have the strongest association compared to the **>80 y** age group (OR 2.1). - Statistical significance confirms the association is real, but effect size (OR) determines strength of association. *<50 y age group serves as the reference category* - The table shows an **Odds Ratio (OR) of 1.1** for the **<50 y** age group, indicating it is also being compared to a reference (which would have OR = 1.0). - The reference category is not explicitly shown in the table but would typically be an even younger age group or overall population baseline. *50-59 y age group has the highest odds ratio for blindness risk* - The odds ratio for the **50-59 y** age group is **1.2**, which is lower than the **>80 y** age group (OR 2.1), the **70-79 y** age group (OR 1.6), and the **60-69 y** age group (OR 1.5). - This statement is incorrect as the **>80 y** age group clearly has the highest odds ratio for blindness risk.

Question 9: Which of the following indicators can help determine whether the health system is effective at identifying leprosy cases early in the community?

A. Proportion of newly diagnosed patients with grade 2 disability (Correct Answer)
B. Annual new case detection rate per lac
C. Treatment initiation rate
D. Treatment completion rate

Explanation: ***Proportion of newly diagnosed patients with grade 2 disability*** - A **high proportion of newly diagnosed patients with grade 2 disability** indicates late detection of leprosy, suggesting shortcomings in the health system's ability to identify cases early. - Grade 2 disability in leprosy signifies **visible and irreversible damage** to eyes, hands, or feet, which would likely have been prevented with earlier diagnosis and treatment. *Annual new case detection rate per lac* - The **annual new case detection rate** reflects the number of new cases identified but does not directly indicate the timeliness of detection or the effectiveness of early case-finding efforts. - A high new case detection rate could be due to intensive active case-finding campaigns, but without knowing the disability status at diagnosis, it doesn't confirm early detection by the routine health system. *Treatment initiation rate* - The **treatment initiation rate** measures the percentage of diagnosed patients who start treatment, which is crucial for disease control but does not reflect how early cases are identified. - A high initiation rate indicates good patient adherence to treatment protocols after diagnosis, but not the efficiency of the health system in finding cases before they develop advanced disability. *Treatment completion rate* - The **treatment completion rate** indicates the effectiveness of the treatment program and patient adherence, which is vital for preventing drug resistance and relapse. - This metric does not provide information about when the diagnosis was made in the disease progression or the health system's ability to identify cases early.

Question 10: Abdominal TB can occur through all of the following EXCEPT

A. Direct spread from mesenteric lymph nodes
B. Feco - oral route
C. Direct contact with infected animal (Correct Answer)
D. Hematogenous spread

Explanation: ***Direct contact with infected animal*** - While animal products like **unpasteurized milk** can transmit *Mycobacterium bovis* to humans, direct contact with an infected animal is not a primary mode of transmission for **abdominal TB**. - **Abdominal TB** is usually caused by *Mycobacterium tuberculosis* which is primarily a human pathogen, not typically transmitted through direct contact with animals. *Direct spread from mesenteric lymph nodes* - **Mesenteric lymph nodes** are often involved in abdominal TB, and the infection can directly spread from these nodes to adjacent abdominal organs. - This is a common mechanism for localized propagation within the abdominal cavity. *Feco - oral route* - The **ingestion of contaminated food or milk** (from infected cattle) containing *Mycobacterium bovis* or swallowing of **infected sputum** (from pulmonary TB) containing *Mycobacterium tuberculosis* are common ways the bacteria can reach the gastrointestinal tract. - This leads to primary intestinal infection or reactivation of previously ingested bacteria. *Hematogenous spread* - **Hematogenous dissemination** from a primary pulmonary or other mycobacterial focus is a significant mode of transmission for abdominal TB. - Bacteria can travel through the bloodstream and seed distant abdominal organs, including the **peritoneum**, **intestines**, or **mesenteric lymph nodes**.
