JEFFERSON - The Jefferson County Health Department has reported that a dead blue jay found in Jefferson County has tested positive for West Nile virus. This is the first bird to test positive in the county since surveillance for the mosquito-transmitted disease began May 1.

“The positive means that residents of Jefferson County need to be more vigilant in their personal protective measures to prevent mosquito bites,” Jefferson County Health Officer/Public Health Director Gail Scott said.

She noted West Nile virus is spread to humans through the bite of an infected mosquito. Mosquitoes get the virus by feeding on infected birds.

“Jefferson County residents should be aware of West Nile virus and take some simple steps to protect themselves against mosquito bites,” Scott said. “The West Nile virus seems to be here to stay, so the best way to avoid the disease is to reduce exposure to, and eliminate the breeding ground of mosquitoes.”

The Jefferson County Health Department recommends persons maintain window screens in the home; avoid going outside at dawn and dusk when mosquitoes are most active; wear light-colored clothing to repel the insects and tuck in pant-legs when outdoors; use mosquito repellents with DEET, picaridin or oil of lemon eucalyptus; and remove all potential mosquito breeding grounds such as old tires or other items where the insects can lay eggs.

“The majority of people who are infected with West Nile virus do not get sick,” Scott said. “Those who do become ill usually experience mild symptoms such as fever, headache or rash. Less than 1 percent of people infected with the virus get seriously ill.”

Jefferson County, in cooperation with the Wisconsin Division of Health, will continue surveillance for West Nile virus until the end of the mosquito season. Sick or dead crows, blue jays or ravens should be reported to 1-800-433-1610.
