African swine fever (ASF) is a highly infectious and fatal haemorrhagic disease of pigs
that is caused by a complex DNA virus of the genus Asfivirus and Asfarviridae African suids family.
The disease is among the most devastating pig diseases worldwide including Africa. Although
the disease was first reported in the 19th century, it has continued to spread in Africa and other
parts of the world. Globally, the rising demand for pork and concomitant increase in transboundary
movements of pigs and pork products is likely to increase the risk of transmission and spread of ASF
and pose a major challenge to the pig industry. Different genotypes of the ASF virus (ASFV) with
varying virulence have been associated with different outbreaks in several countries in sub-Saharan
Africa (SSA) and worldwide, and understanding genotype circulation will be important for ASF
prevention and control strategies. ASFV genotypes unique to Africa have also been reported in SSA.
This review briefly recounts the biology, genomics and genotyping of ASFV and provides an account
of the different genotypes circulating in SSA. The review also highlights prevention, control and
progress on vaccine development and identifies gaps in knowledge of ASFV genotype circulation in
SSA that need to be addressed.
