A dead crow found in Langlade County has tested positive for West Nile Virus.
This makes it the fifth County in central and northern Wisconsin where the virus is present.
"The bird is the vector that carries the disease and the mosquitoes get the disease from biting the birds," said Diane Rodd, Official with the Wood County Health Department.
Health officials add that 80 percent of people who are bitten by mosquitoes infected with the virus won't show any symptoms.
The 20 percent of people who do show symptoms will notice them.
"Those symptoms are very similar to perhaps a tick bite which you might get a headache, achy joints, rash, and fever," added Rodd.
So far this summer, state health officials say one person in Dane County has contracted the virus.
Officials with the Department of Natural Resources say the West Nile Virus is nothing new to Wisconsin.
"We've had West Nile Virus detected in Wisconsin every year pretty much since it was discovered in 2002," said Nancy Businga, official with the Department of Natural Resources.
There are a number of ways that you can reduce the amount of mosquitoes in outdoor areas where you might work or play, one of those ways is to make sure your gutters are clean.
Rodd says other ways can include:
"Making sure that our screens and our screen doors are in good repair so that mosquitoes don't come into our homes and then avoiding standing water as well."
Health officials add that the elderly, younger children, and anyone with an organ transplant should take extra precautions.
Other counties in central and northern Wisconsin with West Nile Virus include Lincoln, Oneida, Vilas and Wood.
If you find a dead bird on your property, notify your local health department.
