In Great Britain (England, Scotland and Wales), dourine is notifiable by law under the Infectious Diseases of Horses Order 1987. Under the Order, anyone who owns, manages, inspects or examines a horse, which is affected or is suspected of being affected by the disease must notify the Animal & Plant Health Agency (APHA). Please see Appendix 1 for APHA contact details. Under the Order, the premises where disease is suspected may be declared to be an infected place and restrictions imposed on horses at those premises. A veterinary enquiry will be carried out by the APHA to determine if dourine is present. The Order also provides Defra with powers to enforce measures for vector control and disinfection.
