West Nile virus season starts early in the valley

May 24, 2013 

Mosquitoes carrying the West Nile virus have been found in two areas of southern San Joaquin County, the earliest positive results since testing began in 2004.

The San Joaquin County Mosquito and Vector Control District said the mosquitoes were discovered in ZIP codes 95337 (a chunk of Manteca extending south to Caswell Memorial State Park) and 95366 (Ripon).

"With this find on the heels of Memorial Day weekend, it is imperative that people take necessary precautions to avoid mosquito bites, as well as removing standing water on their properties," said Aaron Devencenzi, public information officer with the district.

In response, the district will expand testing and spraying for mosquitoes, Devencenzi said.

While most people will not suffer any lasting health issues from a West Nile infection, in rare cases the disease can lead to serious neurological problems and even death. There is no treatment or vaccine for the illness, which is spread to humans by infected mosquitoes.

Thirteen people in San Joaquin County, ranging in age from 11 to 86, were sickened by West Nile in 2012. Six of them suffered from a neurological illness, which is more serious than West Nile fever and can cause permanent impairment.
