National health officials say the West Nile virus is here to stay, and simple prevention efforts, such as wearing insect repellent, are the best way to manage the epidemic.
Center for Disease Control Director Doctor Julie Gerberding says she wasn't surprised human infections have risen since the disease spread south and west from New York, where it was first seen in 1999. The disease has been found in more than 100 people nationwide this year.
Gerberding says officials should spray for mosquitoes when the virus has been detected, and people should eliminate standing water to reduce risk.
Five Louisiana residents have died this summer of West Nile, a virus that can cause flu-like symptoms and sometimes potentially fatal swelling of the brain.
Wisconsin's first case this year found in a bird was reported in June. Last year 58 birds with the virus were found in Wisconsin.
No one in Wisconsin has been diagnosed with the disease.
