According to FAO, ASF is a highly contagious, generalized disease of pigs caused by an Iridovirus of family Asfarviridae that exhibits varying virulence between strains and is very hardy to physical and chemical inactivation. The agent can remain viable for long periods in blood, feces and tissues. It can also multiply in its vectors. In view of this, the control of ASF is dependent on stamping out policy and strict quarantine enforcement. It most commonly appears in the acute form as a hemorrhagic fever. Subacute and chronic forms of the disease also exist. Mortality is usually close to 100 percent and pigs of all ages are affected.
