Second Human Case of West Nile Virus Reported in Vermont This Season

The Vermont Department of Health confirmed today the second case of human illness due to West Nile virus infection this year. A Chittenden County resident became ill in in late September and has since recovered.

This season, West Nile virus has been detected in mosquito pools in 12 different towns including Milton and Colchester in Chittenden County. Mosquito surveillance was conducted mainly in southern Addison and northern Rutland Counties with limited trapping and testing done in parts of Franklin and Chittenden counties.

While the peak of West Nile activity is usually in late August and early September, mosquitoes will remain active until the first widespread hard frost.

Most people who become infected with West Nile Virus do not become ill, about 20 percent experience a flu-like illness, and fewer than 1 percent develop a more severe illness that affects the nervous system. Symptoms of West Nile virus typically include high fever, muscle aches, headache and fatigue. When the nervous system is involved, symptoms may include a stiff neck and a severe headache.
