African horse sickness: how to spot and report the disease

How to spot African horse sickness, what to do if you suspect it and measures to prevent its spread.

African horse sickness affects horses.

It doesn’t affect humans.

There has never been an outbreak in Great Britain.

African horse sickness is a notifiable disease. That means if you suspect it you must tell the Animal and Plant and Health Agency (APHA) immediately. Failure to do so is an offence.
