Both of the first human cases of West Nile Virus are in Dane County.
The Madison Health Department says a person became infected in mid–July and has been hospitalized. Doctor Kathryn Vedder says that person has developed West Nile encephalitis. That's a severe form of the disease that can lead to inflammation of the brain.
A second Dane County resident developed West Nile fever.
The virus can be deadly, but most people infected with it suffer flu–like symptoms such as fevers and headaches.
