The Connecticut Department of Public Health announced today it had trapped mosquitoes that tested positive for West Nile virus. The mosquitoes were trapped at the Rowayton School in Norwalk on July 2.

The state began this year’s testing June 17, at 91 mosquito-trapping stations in 72 municipalities. So far, 57,361 mosquitoes have been tested. In addition to the single mosquito testing positive for West Nile, seven have tested positive for Jamestown Canyon virus.

There are two mosquito traps in Wilton: on Saunders Drive and Spectacle Road. Ninety-five mosquitoes have been trapped on Saunders Drive and 668 on Spectacle Road. None tested positive for any of the three diseases the Department of Public Health looks for: West Nile, Jamestown Canyon and Eastern equine encephalitis.

“The West Nile virus season has started,” said Dr. Theodore Andreadis, chief medical entomologist at the Connecticut Agricultural Experiment Station. “Early- to mid-July is when we typically start to see an increase in infected mosquitoes and is a reminder for people to take steps to protect themselves from mosquito bites now through September.”

Last year, mosquitoes positive for West Nile virus were trapped in 44 municipalities, including one mosquito in Wilton. Twenty-one people in the state contracted a West Nile infection last year, the highest number of human cases of West Nile identified in Connecticut since surveillance began in 2000.

Last year, 286 fatalities in 48 states were reported to the Centers for Disease Control and Prevention. The majority were in the South and Midwest.
