Although we are experiencing cooler evenings and mosquito numbers are down, residents should continue to practice personal protection measures to avoid being bitten by mosquitoes until the first hard frost. Mosquitoes are most active between dusk and dawn.  Personal protection is advised during outdoor activities.  Personal protection measures include wearing shoes and socks, long pants, and a long-sleeved shirt when outside for a long period of time.  Applying a mosquito repellent containing DEET, Picaridin, Oil of Lemon Eucalyptus, or IR3535 is also recommended to prevent mosquito bites.

Symptoms of EEE disease often appear 4 to 10 days after someone is bitten by an infected mosquito. If you or someone you know is experiencing flu-likesymptoms, including fever and headache, contact your local medical provider. EEE is a more serious disease than WNV and carries a high mortality rate for those who contract the serious encephalitis form of the illness. Symptoms may include high fever, severe headache, stiff neck, and sore throat. There is nospecific treatment for the disease, which can lead to seizures and coma.
