Primarily transmitted to humans through the bite of an infected mosquito, West Nile Virus is an arthropod-borne virus that typically shows few or no symptoms in humans, but in rare cases, can be fatal.
Anyone that spends time outdoors is at risk of West Nile, however the risk varies from year to year depending on the amount of rain, how hot it gets, and the current population of mosquitoes. Mosquito populations reach their peak in the summer months, so right now is the time to be protecting yourself against mosquitoes.
