When it comes to outdoor fitness activities at night, it's important to consider the potential risks of mosquito bites. Mosquitoes can spread West Nile virus (WNV), and there is no vaccine to prevent infection. To protect yourself, you should use insect repellent that contains DEET, picaridin, lemon or eucalyptus oil. These are all effective against mosquitoes. In addition to using insect repellent, you should also wear long-sleeved shirts and pants, treat clothing and equipment, and take steps to control mosquitoes indoors and outdoors.
This will help reduce your risk of being bitten by a mosquito and contracting WNV.
