Equine infectious anaemia (horses, mules and donkeys)

Notify us immediately
  • If you suspect disease call +44 (0) 1534 441600.

About the disease

Equine infectious anaemia (EIA) is a notifiable disease that affects:

  • horses
  • mules
  • donkeys

The disease can also be called swamp fever. It's caused by a virus and is spread via biting insects.

EIA does not affect humans.


The signs of equine infectious anaemia are:

  • intermittent fever
  • anaemia
  • emaciation


If disease is confirmed, the only course of action is to humanely destroy the infected animal.

Animals are infected for life and destruction prevents a welfare problem for the affected animal and a source of infection for other animals.
