==Aetiology==

The Classical Swine Fever Virus is a Togavirus. Togaviruses belong to the genus Pestivirus, within the Flaviviridae family. The virus is enveloped, and has a positive-sense, single stranded RNA genome that is approximately 12.3kb long. Classical swine fever virus is closely related to the bovine viral diarrhoea virus of cattle, and the border disease virus of sheep.

 

 

The causative agent of classical swine fever is a small, enveloped virus of around 40nm diameter. The genome is comprised of single stranded RNA, which is positive sense and contains about 12,300 bases. The sequence of the genome is known, and codes four structural and seven non-structural proteins. The classical swine fever virus is relatively stable in excretions and in fresh meat products including ham, salami and other similar sausages. It is, however, easily inactivated by detergents, common disinfectants and heat.
