EEE Virus in Connecticut: Map & Updates

A third death has been reported in Connecticut from the EEE virus. Eastern equine encephalitis is transmitted by mosquitoes and while the illness is still rare in humans, an increasing number of cases are being reported as 2019 comes to an end. Connecticut is one of several states reporting human cases and deaths.

EEE symptoms can start out as fever, chills, and joint and muscle pain, the Texas Department of State Health Services notes. Some people only have mild flu-like symptoms but others develop more serious illnesses. About half of those go on to develop the encephalitic disease, StatNews reported.

When the illness gets more serious, the symptoms can be a sudden and severe headache, a high fever, vomiting, diarrhea, disorientation, convulsions and seizures, and even coma. If you get a high fever of 103 to 105 that comes on rapidly with a severe headache, you should see a doctor right away, Fox 61 reported.

Although still considered rare, the disease can have a 33 percent mortality rate in those who develop the encephalitis symptoms. The incubation period for the illness is four to 10 days. There’s a vaccine for horses, but there’s currently no vaccine for humans.
