Two Marquette County Horses Test Positive For EEE Virus

The Marquette County Health Department reported on Thursday that two horses in the county have tested positive for Eastern Equine Encephalitis (EEE) infections.

Neither horse had been previously vaccinated against EEE.

While it is unusual to have EEE detected in the U.P., a horse from Menominee County tested positive and one human case of EEE was diagnosed in the U.P. in 2016.

Six EEE infections have been diagnosed in horses in Michigan in 2017. The additional four cases are in Lower Michigan.

EEE is a serious viral disease transmitted by mosquitoes. The virus mainly causes neurological disease in horses but can also cause illness in people, poultry and other animals such as deer and even dogs.

Animals becoming sick from EEE are an indication that infected mosquitoes may be present in the region.

It is recommended that people take steps to safeguard themselves against mosquito bites by applying repellent, and wearing protective clothing. Managing your property to Control mosquito populations is also recommended.

Although there is no vaccine available to protect against human EEE infection, vaccines for horses to protect them from EEE and other mosquito-borne diseases are available.

Horse owners should contact their veterinarian to make sure their animals are up-to-date on all vaccinations.
