What are the symptoms of equine encephalitis?
Most severe human cases begin with a sudden onset of fever, headache, stiff neck, vomiting, or weakness. The illness may progress to disorientation, irritability, seizures and coma. Approximately 5-15% of these encephalitis cases are fatal, and about 50% of surviving infants will have permanent brain damage.
Is Equine encephalitis curable?
There is no cure for EEE. Treatment largely consists of supportive care for horses with clinical signs, including intravenous (IV) fluids and anti-inflammatory medications.
How is encephalitis treated in horses?
There is no specific treatment for viral encephalitis. Supportive care includes intravenous fluids if the horse is unable to drink, use of appropriate anti-inflammatory agents, and anticonvulsants if necessary. Good nursing care is essential.
Is equine encephalitis contagious?
A horse affected with EEE is not contagious and poses no risk to other horses, humans or birds. Carrier status: Infected horses cannot transmit the disease to other horses. The virus can only be transmitted to a horse via an insect vector.
How do horses get equine encephalitis?
It is spread by the bite of a mosquito infected with EEE virus (EEEV). EEEV can also infect a wide range of animals including mammals, birds, reptiles, and amphibians. The spread of EEEV to mammals (including humans and horses) occurs through the bite of infected mosquitoes that feed on both birds and mammals.
How do animals get encephalitis?
How can my animal get Japanese encephalitis? Japanese encephalitis is spread through the bite of an infected mosquito (vector). Some animals, especially infected pigs and birds, can have large amounts of the virus in their blood and serve as a major source of the virus (reservoir) for mosquitoes.
What causes equine encephalitis?
Eastern equine encephalitis (EEE) is an extremely rare but serious and often fatal infection that causes encephalitis or inflammation of the brain. It is spread by the bite of a mosquito infected with EEE virus (EEEV). EEEV can also infect a wide range of animals including mammals, birds, reptiles, and amphibians.
Is there a vaccine for equine encephalitis?
Actually, there is a human vaccine for eastern equine encephalitis (EEE), but it has never been approved for public use. The U.S. Army Medical Research Institute of Infectious Diseases—the military medical research institute at Fort Detrick in Maryland—developed a human EEE vaccine in the mid-1980s.

How do you prevent equine encephalomyelitis in horses?
What can I do to prevent Eastern Equine Encephalitis?
- Vaccinate your horses for EEE at least twice yearly.
- Remove sources of standing water in pastures on your property.
- Apply fly masks, fly sheets and/or fly leggings to horses when they are at pasture.
- Spray horses with insect repellent.
Can encephalitis be cured?
Most people who have mild encephalitis fully recover. The most appropriate treatment and the patient’s chance of recovery depend on the virus involved and the severity of the inflammation. In acute encephalitis, the infection directly affects the brain cells.
What is encephalitis in animals?
Encephalitis can happen on its own, but it may be a symptom of other diseases affecting the brain and spinal cord, such as a viral or bacterial infection.
