Which prevention measure is recommended to reduce West Nile Virus risk?

• A. Using insect repellent containing DEET.
• B. Vaccination against West Nile Virus.
• C. Limiting outdoor activity entirely.
• D. Relying on antibiotics to prevent infection.

Answer: (A)

Preventing mosquito bites is the most effective way to lower the risk of West Nile virus infection. Insect repellent containing DEET works by deterring mosquitoes from landing on you, directly reducing your exposure to the virus. Use it according to the label, choosing a concentration appropriate for your age and activity, and reapply as directed. Combine this with other practical steps like wearing protective clothing, keeping screens intact, and removing standing water around your home to further minimize risk.

Vaccination against West Nile virus isn’t available for people, so it isn’t a preventive option. Completely limiting outdoor activity is not practical for most people, and even brief outdoor time can lead to bites. Antibiotics don’t prevent viral infections like West Nile virus, since they target bacteria, not viruses.
