Via Courant.com: Equine Encephalitis Detected In Mosquito, First Time This Year. Excerpt:
A mosquito trapped in Cheshire has tested positive for eastern equine encephalitis, the first one to be found with the disease in Connecticut this year, state officials announced Wednesday.
Mosquitoes testing positive for West Nile virus have been found in 40 municipalities so far this year. In the last count, one week ago, West Nile-carrying mosquitoes had been found in only 32 town and cities.
Of the two diseases, EEE is much rarer than West Nile and a lot deadlier. Connecticut has never had a confirmed human case of EEE, although it has been confirmed in other parts of New England.
Severe cases of EEE can lead to inflammation of the brain, seizures and coma. One-third of the people who get it die from it.
"While the identification of mosquitoes infected with eastern equine encephalitis virus occurs during most years, the detection of infected mosquitoes this early in the season is of concern," state entomologist Theodore Andreadis said.
"Fortunately, the numbers of Culiseta melanura, the species that is primarily responsible for intensifying the level of virus activity, are relatively low, indicating a low risk of transmission to people at this time."
West Nile virus was first identified in the U.S. in 1999. Since then, Connecticut has had 79 human cases and three fatalities. There have been no human cases in the state this year.
