Infected mosquitoes found in town

The State of Connecticut Mosquito Management Program verified that mosquitoes trapped in Old Greenwich on July 9 have tested positive for West Nile virus (WNV).

These are the first mosquitoes that have tested positive in Greenwich this year, according to the Connecticut Agricultural Experiment Station. The recent warm weather and storm activity have increased the ability for mosquitoes to breed, Director of Health Caroline Calderone Baisley stated in a press release from the town’s health department.

The mosquitoes trapped are generally bird and mammal biting, which breed in standing water often found in artificial containers like discarded tires, birdbaths and catch basins. The health department urges residents to eliminate standing water on their own properties and to protect themselves from mosquito bites at all times.

The town continues to fight WNV by conducting a larviciding program, which includes the treatment of public and private roadway catch basins, public school ground catch basins and other property owned and operated by the town as needed.

WNV is spread to humans by the bite of an infected mosquito, which itself becomes infected when it bites a bird carrying the virus. WNV cannot spread by person-to-person contact or directly from birds to people. General symptoms occur suddenly 5 to 15 days after being bitten by an infected mosquito.

The State Mosquito Management Program will continue to trap and test mosquitoes in Greenwich and will increase the monitoring at the Old Greenwich mosquito testing site. The highest risk of exposure to infected mosquitoes is during August and September. The trapping program continues through October 2012.
