Mosquitoes trapped in Voluntown have tested positive for eastern equine encephalitis, according to the latest report from the Connecticut Agricultural Experiment Station.
According to the Mosquito Trapping and Testing Report, mosquitoes trapped at Mt. Misery in Pachaug State Forest on July 31 tested positive for EEE.
These are the first mosquitoes found to test positive for EEE this year.
Eastern equine encephalitis is one of the most severe mosquito-transmitted diseases in the United States, according to the Centers for Disease Control and Prevention.
It is rare in humans, but there are a few cases reported in the U.S. each year, according to the CDC.
Symptoms of serious cases include the sudden onset of headache, high fever, chills, and vomiting. From there, a patient may become disoriented, have seizures or even fall into a coma.
One-third of those affected will die and most survivors are left with significant brain damage, according to the CDC.
Last week mosquitoes trapped in East Haven tested positive for West Nile virus.
