Name two common vector-borne diseases and primary prevention strategies used in communities.

• A. Malaria and dengue; eliminate standing water, bed nets, and insect repellent.
• B. Common cold and flu; vaccination first.
• C. Tuberculosis and HIV; antibiotic therapy.
• D. Diabetes and hypertension; lifestyle changes.

Answer: (A)

The main idea is preventing diseases spread by insects, especially mosquitoes, through community actions that reduce contact with the vector. Malaria and dengue are two common illnesses transmitted by mosquitoes, so the primary prevention focuses on cutting mosquito bites and their breeding opportunities. Eliminating standing water removes breeding sites, bed nets—especially insecticide-treated nets—protect people while they sleep, and using insect repellent reduces bites when people are outdoors. These measures address both the source of risk and the exposure pathway, making them the best fit for community prevention. The other options involve illnesses that aren’t vector-borne or rely on different prevention approaches (medical treatment or non-vector risk factors), so they don’t align with the scenario.
