West Nile Virus was detected in Visalia, Dinuba and Orosi by the Delta Vector Control District last week. Tulare County residents should protect themselves as outdoor activities ramp up during the holiday weekend, officials said.

The Delta Vector Control District is the mosquito abatement district in the north county. Tulare has the Tulare Mosquito Abatement District. There is no such district in the Porterville area.

According to the Centers for Disease Control and Prevention, the West Nile virus is transmitted to humans by mosquitoes, and there is no vaccine or medication to treat the virus. Most people infected with West Nile will have no symptoms; however, about one in five people will develop a fever with other symptoms.

Community members are urged to be aware of mosquito breeding grounds, such as homes that are unoccupied or in foreclosure that may have swimming pools or backyard ponds.

To avoid contracting the disease, residents are advised to:

 use an effective mosquito repellent.

 dress in long sleeves and pants at dawn and dusk or in areas where mosquitoes are active.

 drain standing water that may produce mosquitoes.

 repair or replace door and window screens that have tears or holes.

Residents can help track the West Nile Virus by reporting dead birds and squirrels by calling 1-877-968-2473. Online reports can be submitted at http://westnile.ca.gov/.
