AUGUSTA - The Maine Center for Disease Control and Prevention in the Maine Department of Health and Human Services and the Maine Department of Agriculture’s Animal Health and Industry Division announced today that a second horse in Waldo County has died of Eastern Equine Encephalitis (EEE).
EEE is a virus that is transmitted through the bite of an infected mosquito that has picked up the virus by feeding on an infected bird. The disease was first detected in Maine in 2005 among some horses, mosquitoes, and birds in York County. Last week a horse that had died in Troy was identified with EEE. The horse this week was from Thorndike, about five miles away. It was also not vaccinated.
"These two dead horses with EEE indicate that local mosquitoes are infected, contracting it from birds," said Dr. Dora Anne Mills, Director of the Maine CDC. "Since mosquito bites are how EEE is transmitted to humans and horses, it is very important people and horse owners take precautions."
Steps people should consider to protect themselves from EEE include:
The transmission cycle of EEE among birds and mosquitoes is most common in coastal areas and freshwater swamps. Human cases occur relatively infrequently, largely because the primary transmission cycle takes place in swamp areas where human populations tend to be limited. Those people at most risk are:
"All horse owners should be sure their horses are current on their EEE vaccination, as this is a very effective vaccine," reminded Dr. Don Hoenig, DVM, State Veterinarian.
Maine CDC is working with partners to trap and test mosquitoes in the Troy and Thorndike areas to help determine the scope of the risk. Area Maine CDC staff are also working with community members to inform them of the risks and of their options.
