West Nile found in Oswego mosquitos

Updated: July 1, 2011 2:16AM



A batch of mosquitoes in Oswego have shown signs of carrying the West Nile virus, the first positive test in mosquitoes in Northern Illinois this year.

On Thursday, the Illinois Department of Public Health said mosquito samples collected on Tuesday in Oswego and Evergreen Park tested positive. The first positive mosquitoes this year were collected on June 10 in Tazewell County near Peoria, and the first West Nile virus positive birds were collected on June 8 in LaSalle County. Mosquitoes collected on Tuesday in St. Clair County have also tested positive.

“We are starting to see West Nile virus in mosquitoes and birds, and when temperatures rise and conditions dry up, we typically see increased reports of West Nile virus,” said Damon Arnold, state public health director.

West Nile virus is transmitted through the bite of a mosquito that has been infected with the virus. Most people with the virus have no clinical symptoms of illness, but some may become ill three to 15 days after the bite of an infected mosquito,
