West Nile Virus is Here
West Nile virus (WNV) infection can cause serious disease. WNV is a seasonal health risk in California and San Joaquin County that flares up with the warm weather in late spring or summer and continues into the fall.
Birds are carriers of West Nile virus; a mosquito becomes infected by biting an infected bird. Infected mosquitos can spread the virus to humans, horses, and birds. The easiest and best way to avoid WNV is to prevent mosquito bites.
