π¦ What is rabies?
Rabies is a fatal neurologic disease that all mammals are susceptible to. It is caused by a
virus in the genus Lyssavirus.
π¦ How is it transmitted?
Rabies infection usually occurs by the bite of a rabid animal. However, rabies can be transmitted when fresh saliva from a rabid animal contacts a wound or mucous membranes. Horses are bitten on the legs or face by a rabid animal. After the bite, the virus migrates to the spinal cord and brain where it causes inflammation of the brain (encephalitis).
π΄ What are the clinical signs of rabies in horses?
π¦ Inability to stand (Loss of hindlimb
perception)
π¦ Ataxia
π¦ Aggressiveness
π¦ Self-mutilation
π¦ Muscle weakness
π¦ Loss of tail and a**l sphincter tone
π¦ Sensitivity to touch
π¦ Muscle fasciculations
π¦ Lameness
π¦ Anorexia
π¦ Colic
π¦ Lethargy
π¦ Fever
After the onset of clinical signs, the survival time may range from 2 to 5 days.
π¦ How is it diagnosed?
Unfortunately, a confirmed diagnosis occurs post-mortem when the laboratory evaluates the brain and salivary gland tissues.
π¦ What is the treatment?
Sadly, no treatment options are available for rabies.
π How is rabies prevented?
π Fortunately, a vaccine is available for horses. Initially, naive horses must receive two doses of the vaccine 3-4 weeks apart. Thereafter, the vaccine is given once a year.
π If a vaccinated animal is bitten by or comes in contact with, a rabid animal, they must receive a booster rabies vaccine within 5 days of the exposure.
π If an unvaccinated animal is exposed to a rabid animal, New York State recommends euthanasia. The only alternative is 6 months of observation in a state-approved isolation facility.
π¨ All pet animals (livestock for fairs and public events) are required to be vaccinated against this fatal neurologic disease.
