-==Legislation==
-Diseases caused by some of the viruses listed above (**) are subject to The Infectious Diseases of Horses Order 1987.  "''The Order, which revoked and replaced earlier legislation, makes these diseases compulsorily notifiable: it gives an inspector powers to declare an infected place where disease is suspected; to carry out a veterinary inquiry, prohibits the movement of horses carcases and other things onto or off the premises and requires cleansing and disinfection''".  Council Directive 90/426 describes all cases of equine encephalomyelitis (regardless of cause) as compulsorily notifiable to the EU.<ref>http://www.defra.gov.uk/foodfarm/farmanimal/diseases/atoz/viralenceph/index.htm</ref>
