The Michigan Department of Agriculture and Rural Development reported today of a confirmed Eastern Equine Encephalitis (EEE) case in a 2-year-old horse from Livingston County.
This is the first case in the state in 2021.
This discovery underscores the need for both horse owners and Michigan residents to take precautions. EEE is one of the most dangerous mosquito-borne diseases in the U.S. with a 90 percent fatality rate among horses that become ill and a 33 percent fatality rate among humans who become ill. Last year, Michigan experienced 41 cases of EEE in animals and four cases in humans.
“The Livingston County horse was never vaccinated against EEE, and it developed signs of illness-including fever, lethargy, and depression-which progressed to the animal exhibiting neurologic signs and being down on the ground with an inability to get up. The horse was euthanized due to her declining condition,” said Wineland. “It is critically important for horse owners to reach out to their veterinarian to discuss how to best protect their animals from this disease.”
To protect your animals, measures could include the following:
- Talking to a veterinarian about vaccinating horses against EEE.
- Placing horses in a barn under fans (as mosquitoes are not strong flyers) during peak mosquito activity from dusk to dawn.
- Using an insect repellant on the animals approved for the species.
- Eliminating standing water on the property-i.e., fill in puddles, repair eaves, and change the water in buckets and bowls at least once a day.
- Contacting a veterinarian if a horse shows signs of the illness: mild fever and stumbling, which can progress to being down and struggling to stand.
People can also be infected with EEE from the bite of a mosquito carrying the virus. The disease is not spread by horse-to-horse or horse-to-human contact. In humans, signs of EEE include the sudden onset of fever, chills, and body and joint aches. The virus can also cause severe encephalitis, resulting in headaches, disorientation, tremors, seizures, and paralysis. Permanent brain damage, coma, and death may occur in some cases.
“This equine case indicates the EEE virus is here in Michigan and provides a warning that residents could also become infected by a mosquito,” said Dr. Joneigh Khaldun, MDHHS chief medical executive and chief deputy director for health. “Michigan residents are urged to take precautions and protect themselves from mosquito bites.”
Residents can stay healthy by following steps to avoid mosquito bites:
- Applying insect repellents containing the active ingredient DEET (or other U.S. Environmental Protection Agency-approved products) to exposed skin or clothing, and always following the manufacturer’s directions for use.
- Wearing long-sleeved shirts and long pants when outdoors. Applying insect repellent to clothing to further prevent bites.
- Maintaining window and door screening to help keep mosquitoes outside.
- Emptying water from mosquito breeding sites around the home, such as buckets, unused children’s pools, old tires, or similar sites where mosquitoes may lay eggs.
- Using nets and/or fans over outdoor eating areas.
