Which substance is recommended for application to exposed skin to help reduce malaria risk?

Mosquito repellent with DEET is recognized as an effective measure for preventing mosquito bites, which is crucial in reducing the risk of malaria transmission. DEET (diethyltoluamide) is a widely used active ingredient in insect repellents that works by masking scents that attract mosquitoes, thereby significantly decreasing the chances of being bitten.

The use of DEET is supported by health organizations and is known to provide long-lasting protection even in areas where malaria is prevalent. Other substances, while they may have some protective properties, are not as effective as DEET when it comes to preventing mosquito bites. For instance, coconut oil and neem oil can have mild repellent effects, but they do not offer the same level of efficacy and duration of protection as DEET. Sunblock lotion, while important for skin protection against UV rays, does not repel mosquitoes and does not contribute to reducing malaria risk.

This understanding emphasizes the importance of using proven repellents like DEET in areas where malaria is a concern, making it the recommended choice for application to exposed skin.
