The recent finding of a dead bird that tested positive for West Nile Virus (WNV) is an indication that the WNV season is starting earlier than usual in San Joaquin County. “It is time for everyone to take precautions against the dangers of West Nile Virus (WNV),” urges Dr. Alvaro Garza, San Joaquin County Public Health Officer.
Warm and wet weather promotes the breeding of mosquitoes. Mosquitoes become infected with WNV when they feed on birds that harbor the virus. West Nile Virus is transmitted to humans and animals through the bite of a mosquito carrying the virus. No cases of human WNV illness have been reported in California to date.
