West Nile virus confirmed in dead birds found in Contra Costa County

West Nile Virus

This is the first detection of the virus in Grant County this season and the 11th positive mosquito sample in Washington in 2017. Mosquitoes acquire WNV by feeding on infected birds. Humans can't get the virus from each other or from birds.

The department offers free mosquito control kits to treat standing water.

The majority of people - 80 percent - who are infected with WNV do not get sick. Symptoms of the West Nile Virus, include body aches and headaches. "They are our partners in mounting a defence against mosquitoes that can carry West Nile Virus and preventing people from becoming ill". "Elderly persons and other people with weak immune systems are at highest risk of developing severe illness".

Because WNV is known to be now circulating, Wisconsin residents and visitors to the state should be vigilant in taking measures to prevent mosquito bites.

Spring is the best time to vaccinate horses, but vaccines can still be effective now.

The MADs will continue with their surveillance programs identifying mosquito breeding sources and mosquito-borne disease activity.

"We urge all citizens.to take precautions when in mosquito prone areas", reads the release.

The Health Department asks the public for help with the collection of dead birds.

Last week, the district reported the first West Nile virus activity of the year in the county after two birds in Walnut Creek and mosquitoes in Discovery Bay tested positive. During 2016, 13 cases of WNV were reported among Wisconsin residents.

IDPH says, however, that human cases are often under-reporterd.

The health department maintains a Personal Protection Index (PPI) on the county's website to let residents know about the spread of the virus.
