HARTFORD, Conn. (AP) — Connecticut epidemiologists say the state is seeing an unusually high number of mosquitoes infected with the deadly West Nile virus.

The Connecticut Agricultural Experiment Station has so far found virus-infected mosquitoes in 19 municipalities this year.

No cases have turned up in human or horses.

Since 2000, there have been 134 human cases of West Nile virus-associated illnesses and three fatalities in the state.

State officials say recent humid weather has led to a higher than normal mosquito population, contributing to the early proliferation of the virus.
