Statement — Conjunctivitis occurs every year around the monsoon, but this year it appears to be a major epidemic, the worst in four years. Courses of Action — I. Take precautionary measures every four years to check the epidemic. II. Advise people to drink boiled water during the monsoon season.

Answer
Correct Answer: if only II follows
Explanation
Introduction / Context:The pattern described is seasonal (monsoon-linked) with an unusually severe episode this year. Precautions should be continuous during the risk season, not artificially tied to a four-year cycle. Public health advice should target hygiene behaviors that reduce transmission risk.
Given Data / Assumptions:
- Seasonality: monsoon periods see recurring cases.
- Severity: current year is a major epidemic after four years.
- COA I: schedule precautions only every four years.
- COA II: promote boiled/drinking safe water and hygiene during monsoon.
Concept / Approach:COA I is illogical: the disease risk recurs annually; prevention must be seasonal and continuous (hand/eye hygiene, avoiding sharing towels/cosmetics, surface disinfection, safe water). COA II is sensible; while conjunctivitis transmits primarily via contact, overall monsoon hygiene (including safe water) correlates with reduced concurrent infections and promotes general outbreak control practices.
Step-by-Step Solution:
1) Recognize annual risk → reject “every four years.”2) Endorse seasonal hygiene advisories (II) as broadly preventive.3) Conclude only II follows.Verification / Alternative check:Even if intensity spikes every few years, baseline annual precautions remain rational; therefore I does not follow.
Why Other Options Are Wrong:
I/Either/Both: misreads periodicity.Neither: dismisses an obviously useful public-health advisory (II).Common Pitfalls:Confusing episodic peaks with the need for only episodic precautions.
Final Answer:Only II follows.
