Public Health Measures Against Diseases — NEET

Correct answer: B — S2, S3 and S5 are correct

Let's evaluate each statement based on the NCERT text for Human Health and Disease: S1: "Many fungi belonging to the genera Microsporum, Trichophyton and Epidermophyton are responsible for ringworms..." The statement incorrectly identifies the causative agents as helminths; they are fungi. This statement is incorrect. S2: "Appearance of dry, scaly lesions on various parts of the body such as skin, nails and scalp... These lesions are accompanied by intense itching." This statement is correct. S3: "Heat and moisture help these fungi to grow, which makes them thrive in skin folds such as those in the groin or between the toes." This statement is correct. S4: "Ringworms are generally acquired from soil or by using towels, clothes or even the comb of infected individuals." The statement incorrectly mentions transmission via airborne droplets. This statement is incorrect. S5: "Maintenance of personal and public hygiene is very important for prevention and control of many infectious diseases. Measures for personal hygiene include keeping the body clean..." Keeping the body clean and dry directly relates to preventing fungal growth in susceptible areas. This statement is correct. Based on the analysis, S2, S3, and S5 are correct statements. Option A is incorrect because S1 and S4 are false. Option B is correct because S2, S3, and S5 are correct. Option C is incorrect because S1 and S4 are false. Option D is incorrect because it misses S3, which is also correct. The tested concept is a comprehensive understanding of ringworm, including its causative agents, symptoms, conditions favoring its growth, mode of transmission, and preventive measures.
