From Wikipedia, the free encyclopedia
Horse flu (or
Equine influenza) refers to varieties of
Influenzavirus A that are
endemic in
horses. Horse flu viruses were only isolated in
1956. There are two main types of virus called equine-1 (
H7N7) which commonly affects horse heart muscle and equine-2 (
H3N8) which is usually more severe. Horse flu is endemic throughout the world.
The disease has a nearly 100% infection rate in an unvaccinated horse population that has not been previously exposed to the virus. The incubation time is one to five days.
Horses with horse flu can run a fever, have a dry hacking cough, have a runny nose, and become depressed and reluctant to eat or drink for several days but usually recover in 2 to 3 weeks.
"Vaccination schedules generally require a primary course of 2 doses, 3-6 weeks apart, followed by boosters at 6-12 month intervals. It is generally recognised that in many cases such schedules may not maintain protective levels of antibody and more frequent administration is advised in high-risk situations." [1]
It is a common requirement at shows in Britain that horses are vaccinated against Equine flu and a vaccination card must be produced; the FEI requires vaccination every 6 months.[2] [3]
