=====Prevention in the UK=====
 +
*Imported stock must come from virus-free countries that DO NOT vaccinate
 +
*Meat imported from endemic countries must be de-boned
 +
 +
=====In an Outbreak=====
 +
*ANY sign of lesions in a susceptible animal is '''NOTIFIABLE''' to the Divisional Veterinary Officer and local police
 +
*Once diagnosis is confirmed, all animals on the premises must be '''slaughtered and incinerated'''
 +
*Further disinfection of the premises
 +
*Movement is controlled within a 10-mile radius
 +
*Follow-up serology must be performed to ensure no spread has taken place
 +
*'''Ring vaccination''' with relevant subtype to create a barrier of immune animals (although this was not done in the 2001 outbreak)
 +
 +
=====In Endemic Areas=====
 +
*Disease cannot be prevented by slaughter due to large numbers of carrier stock
 +
*Annual '''Inactivated whole virus vaccination''' using local subtypes
 +
**Inactivated by azuridines, using alhydrogel adjuvant for cows, and oil for pigs
 +
**Attenuated virus reverts to virulence
 +
**Subunit vaccines ineffective
 +
**Expensive
 +
**2 initial injections at 4 months (if dams vaccinated), followed by boosters every 6-12 months
 +
**Induces virus-neutralizing antibodies
 +
*Vaccination DOES NOT render meat harmful to consumers, but does affect when it can be exported
