What is the mortality rate of EEE?

Among those who are recognized to have infection the death rate is 50-75%, making it one of the most deadly mosquito-borne diseases in the US. It is estimated that 30% of people who survive EEE will have neurologic deficits.

How does EEE affect the brain?

Once the virus is inside the body, it can replicate and travel in the bloodstream. In rare cases the virus crosses the blood-brain barrier and infects the brain, resulting in swelling of brain tissue, or encephalitis. The EEE virus is not contagious.

Who is at risk for EEE?

People who engage in outdoor work and recreational activities in endemic areas are at increased risk of infection. Persons over age 50 and under age 15 seem to be at greatest risk for developing severe disease when infected with EEEV. Overall, only about 4-5% of human EEEV infections result in EEE.

Is there a test for EEE virus?

What percentage of mosquitos have EEE?

“And of those infected with EEE, only about 2 to 5 percent are estimated to develop encephalitis and only 3 to 15 cases per year of neuroinvasive EEE have been reported annually.
