Eastern equine encephalitis (en-sef-AH-ly-tis) is a rare but serious viral infection. This disease is most common in the eastern half of the United States and is spread by the bite of an infected mosquito. EEE can affect humans, horses and some birds. The risk of getting EEE is highest from late July through early October.

Who gets EEE?

How do people get EEE?

What are the symptoms of EEE?

Some people infected with EEE do not become ill and may not develop symptoms. When symptoms do occur, they may be mild or severe and show up 3 to 15 days after being bitten by an infected mosquito.

• Mild symptoms such as flu-like illness with fever, headache, sore throat, stiff neck, lack of energy, muscle aches and confusion.

• Severe cases include swelling of the brain (encephalitis) which can lead to coma, convulsions and death.

How is EEE diagnosed?

If a health care provider suspects EEE, samples of the patient’s blood or spinal fluid will be examined.

Is there a treatment for people with EEE?

ALWAYS follow the directions on the product label.

Mosquitoes begin to breed in any puddle or standing water that lasts for more than four days. Get rid of mosquito breeding sites around the home.
