In a deployment area where malaria is endemic, what is the role of preventive medicine in controlling vector-borne diseases?

• A. Implement vector control, provide prophylaxis/vaccination as applicable, conduct disease surveillance, educate personnel, and reduce exposure to vectors.
• B. Implement vector control only.
• C. Provide prophylaxis only.
• D. Educate personnel only.

Answer: (D)

In a deployment area where malaria is common, the best approach is a comprehensive preventive medicine program that combines multiple, complementary actions. Vector control actively reduces the mosquito population and disrupts transmission, while reducing exposure to vectors limits the chance of bites during peak activity times. Providing prophylaxis or vaccination where applicable protects individuals from developing malaria even if exposure occurs. Disease surveillance enables early detection of cases and trends, so responses can be adjusted quickly. Educating personnel ensures they understand and consistently apply protective measures, such as proper use of bed nets, repellents, and protective clothing. Each element supports the others, and together they create a robust defense against vector-borne diseases rather than relying on a single tactic.
