in Health

Stanislaus County Public Health has confirmed the first human West Nile virus (WNV) infection in the county. An adult female was diagnosed with West Nile fever (non-neuroinvasive disease). The first pools of mosquitoes in the county tested positive for West Nile virus on June 11, 2021.

West Nile virus spreads to people and animals through the bite of a mosquito infected with the virus. Hot weather, abandoned swimming pools, and standing water create ideal conditions for the development of mosquitoes and the subsequent spread of the virus. About one in five people will develop West Nile fever with symptoms of headache, fever, and fatigue. However, some people (less than one percent) will develop serious neurologic illness, such as encephalitis or meningitis.

As temperatures continue to rise, so will mosquito populations and virus activity,” said Turlock Mosquito Abatement District Manager David Heft.

Mosquitoes become infected with West Nile Virus when they feed on infected birds. Infected mosquitoes can then spread West Nile Virus to humans and other animals when they bite, according to the Centers for Disease Control.
