What is equine encephalitis?

Equine encephalitis is a mosquito-borne viral disease of horses. It can be caused by several different viruses, including Eastern equine encephalitis virus (EEEV), Western equine encephalitis virus (WEEV), Venezuelan equine encephalitis virus (VEEV), and Japanese equine encephalitis virus (JEV).

The viruses are spread by mosquitoes that have fed on infected birds. When a mosquito bites a horse, the virus can be transmitted to the horse. The virus then multiplies in the horse's body, causing symptoms such as fever, weakness, loss of appetite, and swelling of the brain. In severe cases, equine encephalitis can be fatal.

There are no specific treatments for equine encephalitis. Treatment is supportive and includes providing fluids, electrolytes, and pain relief. In some cases, antiviral drugs may be used.

The best way to prevent equine encephalitis is to vaccinate horses against the disease. There are several different vaccines available, and the type of vaccine that is best for a particular horse will depend on the geographic area where the horse lives and the risk of exposure to the virus.

In addition to vaccination, horse owners can also take steps to reduce the risk of their horses being bitten by mosquitoes, such as:

* Using mosquito repellent

* Removing standing water from around the property

* Keeping horses in barns or under shelters during the times of day when mosquitoes are most active

* Using mosquito netting
