Eastern Equine Encephalitis



Protecting yourself

Protect yourself and your family from the EEE virus and other mosquito-borne viruses by:

  • Using insect repellent that contains DEET.
  • Wearing long-sleeved shirts, pants and socks when outdoors.
  • Installing or repairing window screens.
  • Avoid being outdoors at dawn or dusk.
  • Draining stagnant water.

Eastern equine encephalitis vaccine

There is no EEE vaccine for dogs, cats or people. There is an EEE vaccine for horses. Contact your veterinarian to learn more.

If you think you have Eastern equine encephalitis, book an appointment with your doctor.

Eastern equine encephalitis in horses

Visit the Ontario Ministry of Agriculture and Food’s Equine Neurological Disease web page for the most up-to-date data on EEE in horses.

Actions Peel Region is taking against Eastern equine encephalitis

The Region of Peel is monitoring EEE in Peel annually as part of our Vector Borne Disease Prevention Plan.

Activities in the plan include monitoring Culiseta melanura, the main mosquito that spreads the disease from birds to horses and people.

We monitor this type of mosquito through the Region-wide West Nile Virus adult mosquito-trapping network. Any Culiseta melanura we capture will be tested for the EEE virus. Consistently testing this type of mosquito will give us data that will be used to update and refine our EEE monitoring program.
