Van Buren County, MI — Michigan has reported its first case of Eastern equine encephalitis (EEE) for 2024, detected in a Standardbred filly in Van Buren County. The Michigan Department of Agriculture and Rural Development (MDARD) announced the case earlier this week, noting that the horse was unvaccinated against the mosquito-borne virus.
The Threat of Eastern Equine Encephalitis
Eastern equine encephalitis, commonly referred to as EEE, is a serious virus transmitted by mosquitoes that can cause severe neurological illness in both animals and humans. According to the Centers for Disease Control and Prevention (CDC), the disease has a high fatality rate, with about 30% of infected humans succumbing to the illness. Cases of EEE typically emerge in late summer to early fall.
Precautions Urged by State Health Officials
Dr. Natasha Bagdasarian, Michigan’s Chief Medical Executive, emphasized the risk posed by mosquito-borne illnesses, stating, “It only takes one bite from an infected mosquito to cause a severe illness.” She urged Michiganders to take preventive measures, such as using EPA-registered insect repellents, avoiding areas with high mosquito activity, and wearing protective clothing that covers the arms and legs.
Rising Mosquito-Borne Disease Activity
While this is Michigan’s first confirmed case of EEE this year, the state has already recorded West Nile virus in 48 mosquito pools, 12 wild birds, and one human case. State Veterinarian Dr. Nora Wineland highlighted the significance of these findings, warning that mosquito-borne diseases are actively circulating within the state. “It is crucial to protect animals and people against these insects,” she said.
Recommendations for Animal Owners
MDARD is advising horse owners and other animal caretakers to consult with veterinarians about vaccinating animals against EEE and other mosquito-borne diseases. In addition, owners are encouraged to:
- Eliminate standing water where mosquitoes breed.
- House livestock in barns with fans.
- Keep pets indoors during peak mosquito activity.
- Use insect repellents that are safe for animals.
Protecting Yourself from Mosquito-Borne Illnesses
Residents are also advised to protect themselves by:
- Applying insect repellents approved by the EPA.
- Wearing light-colored, long-sleeved shirts and long pants when outdoors.
- Removing standing water from buckets, kiddie pools, and other potential mosquito breeding sites around the home.
