First case of West Nile virus in Connecticut is reported

The State Mosquito Management Program yesterday announced that a New Haven resident tested positive for West Nile virus infection. This is the first case of human illness associated with West Nile virus infection reported in Connecticut this year.

The person, between 30-39 years of age, had onset of illness during the first week of August and was hospitalized the following week with meningitis related to the West Nile virus infection, a state press release said.

Symptoms included headache, stiff neck, nausea, and muscle weakness. The person has been discharged from the hospital and is recovering. Infected mosquitoes have been repeatedly trapped in New Haven and surrounding communities from July 12 through August 8.

"August and early September is the time of the year when people are at greatest risk of illness associated with West Nile virus infections," said Dr. Randall Nelson, State Public Health Veterinarian with the Department of Public Health. "DPH urges everyone to take the warnings of the risk of mosquito-transmitted illness seriously and take precautions to prevent mosquito bites."

From June 27 to Aug. 8 the Connecticut Agricultural Experiment Station (CAES) has identified West Nile virus positive mosquitoes in 40 towns, including Wilton: Bethel, Bridgeport, Cheshire, Chester, Danbury, Darien, East Haven, Fairfield, Farmington, Glastonbury, Greenwich, Groton, Hamden, Hartford, Killingworth, Meriden, Milford, Monroe, New Britain, New Canaan, New Haven, Newington, Newtown, North Branford, North Haven, Norwalk, Old Lyme, Shelton, South Windsor, Southington, Stamford, Stratford, Wallingford, Waterbury, West Hartford, West Haven, Westbrook, Westport and Wethersfield.

West Nile-positive mosquitoes were trapped in Wilton in mid-July; none have been trapped since.

Mosquitoes positive for eastern equine encephalitis were trapped in Chester on August 8.

The CAES maintains a network of 91 mosquito-trapping stations in 72 municipalities throughout the state. Positive findings are reported to local health departments and on the CAES web site at
