What does the self-protection measure in the enhanced 4S strategy involve?

The self-protection measure in the enhanced 4S strategy involves the use of mosquito repellents. This strategy aims to reduce the risk of mosquito-borne diseases by encouraging individuals to take proactive steps in protecting themselves from mosquito bites. The application of effective mosquito repellents is a critical component, as it creates a barrier against mosquito entry and significantly decreases the likelihood of being bitten.

Utilizing mosquito repellents is particularly important in areas where these diseases are prevalent, as it can provide immediate protection, especially during peak mosquito activity times such as dawn and dusk. In conjunction with other measures like environmental management and personal protective clothing, the use of repellents enhances overall safety and health.

Other options, while they may contribute to overall safety, do not specifically fit under the self-protection measure outlined in the enhanced 4S strategy focused on minimizing the risk of contact with mosquitoes directly.
