Difficulty: Medium
Correct Answer: Both I and II follow
Explanation:
Given data
Concept/Approach (course-of-action evaluation)
In public-health emergencies, simultaneous vector control and behavioral prevention are appropriate, feasible, and urgent.
Step 1: Assess Action I (fumigation)
Fumigation reduces mosquito populations, addressing the source of transmission—clearly relevant and immediate.
Step 2: Assess Action II (advisories)
Advising nets/repellents/long sleeves reduces exposure; it is low-cost and complementary to fumigation.
Step 3: Joint adequacy
Both actions target different parts of the transmission chain; adopting both is prudent.
Verification/Alternative
Combining environmental control with personal protection is standard outbreak response.
Common pitfalls
Assuming an either–or choice. In epidemics, layered interventions are typical.
Final Answer
Both I and II follow.
