Chalk this up as another reason to not want mosquitoes biting you. Health officials in the state are warning residents in southwest Michigan that this year’s plentiful blood sucking population could be harboring a deadly virus.
“If we see more than three cases in a cluster we consider that an outbreak. This is an outbreak,” State Veterinarian Steven Halstead told the Kalamazoo Gazette.
The disease is Eastern Equine Encephalitis. EEE has been confirmed in three horses in the southwest portion of the state, and officials are awaiting word from tests on two other horses. The disease is spread from birds to equines (horses and mules) and can sometimes infect people. The virus effects the brain, causing swelling.
The Centers for Disease Control and Prevention in Atlanta says the disease is rare in humans, but if it develops it is severe.
Severe cases of EEE (involving encephalitis, an inflammation of the brain) begin with the sudden onset of headache, high fever, chills, and vomiting. The illness may then progress into disorientation, seizures, or coma. EEE is one of the most severe mosquito-transmitted diseases in the United States with approximately 33% mortality and significant brain damage in most survivors.
There is no treatment for the virus, only management of the virus’ symptoms.
Health officials are warning people in southwest Michigan to use mosquito repellent and to fix areas where mosquitoes could enter homes.
