What is a common method to minimize exposure to mosquito-borne illnesses, such as the West Nile virus?

Using mosquito repellent before going outside is an effective method to minimize exposure to mosquito-borne illnesses such as the West Nile virus. Mosquito repellents typically contain active ingredients like DEET, picaridin, or oil of lemon eucalyptus, which deter mosquitoes from landing on the skin, thus reducing the likelihood of bites. By applying repellent appropriately, individuals can create a protective barrier that significantly lowers the risk of contracting diseases carried by mosquitoes.

In addition to repellent, other preventive measures involve personal behavior, such as avoiding peak mosquito activity times and wearing appropriate clothing. However, the direct action of applying a repellent is recognized as one of the most proactive and effective steps one can take to reduce immediate exposure to mosquitoes when outdoors.
