CAUSATIVE ORGANISM It is caused by a large DNA virus of the Asfarviridae family, which also infects ticks of the genus Ornithodoros. Although signs of ASF and classical swine fever (CSF) may be similar, the ASF virus is unrelated to the CSF virus. MODE OF TRANSMISSION The spread of ASF is complex and varies depending on the environment, types of pig production systems(indoor or outdoor), the presence/absence of competent tick vectors, human behaviour, and the presence/absence of wild pigs. Mode of transmission may include: • Direct contact with infected domestic or wild pigs; • Indirect contact, through ingestion of contaminated material (e.g. food waste, feed, or garbage); • Contaminated fomites, or biological vectors (soft ticks of the g
