Horse owners urged to vaccinate for EEE

Nebraska Agriculture director Greg Ibach is encouraging horse owners to visit with their veterinarian about vaccinating their animals against Eastern Equine Encephalomyelitis.

A case of the mosquito-borne virus was diagnosed this week in a Keith County horse.

Eastern Equine Encephalomyelitis (EEE) is a viral disease of the equine species that is transmitted primarily by infected mosquitoes.  It affects an animal’s central nervous system.

“This case serves as a reminder to equine owners to visit with their veterinarian regarding measures that can protect their animals from disease,” Ibach said.

State veterinarian Dennis Hughes said vaccines are available to protect against EEE, and it is not too late in the season to consider this option.

“Vaccination will help prevent the horse from contracting the virus, and if they do get it, improve their chances of survival,” Hughes said.

Some clinical symptoms of EEE-infected horses include fever, loss of appetite, weakness, lack of coordination, irritability and abnormal sensitivity to light and sound.

Horse owners are encouraged to take general mosquito-control measures, such as eliminating pools of standing water.  Hughes said owners also may consider moving animals indoors during dawn and dusk, when mosquitoes are most active.

Other preventative measures include: avoid turning on lights inside the stable during evening and overnight; remove birds that are in, or close to, the stable; and use mosquito repellants.

Humans also can contract the EEE virus through the bite of an infected mosquito.  Nebraska Department of Health and Human Services Public Health Veterinarian Annette Bredthauer said human cases are rare, but can be severe causing hospitalization and even death.

People should take general precautions to protect themselves from mosquito bites, such as wearing insect repellant, wearing protective clothing, especially during dawn and dusk when mosquitoes are most active, and eliminating standing water to reduce mosquito breeding sites.
