African Swine Fever Virus (ASFV)

African Swine Fever Virus (ASFV)

An outbreak of African Swine Fever Virus (ASFV) is ravaging Asia’s pig industry and continuing to spread globally. The outbreak began in China in August 2018 and since the initial infection, the country has lost 22% of its pig herd and is predicted to lose up to 50%, representing the largest livestock loss in modern history. The disease has spread to neighboring countries including Mongolia, Russia, Cambodia and Vietnam and there is a high risk of it spreading throughout Europe and to the USA. ASFV is a DNA virus that is transmitted through direct contact with an infected pig, contaminated feed or through the bite of an infected tick. Virus isolates can vary in virulence from highly pathogenic strains that cause acute disease and high mortality (90-100%) to low–virulence isolates that present similar but less intense symptoms making the disease chronic and difficult to diagnose. There is no vaccine or treatment. The genome of ASFV is very large and complex, consisting of over 150 genes with variability in expression, leading to 22 different genotypes of ASFV. Several immunogenic viral antigens have been identified, including p30 which is one of the most antigenic structural proteins involved in ASFV entry and is expressed very early on in infection (2-4 hours post-infection) (Zhang

et. al., 2017) . Research has shown that with low-virulence strains, virus shedding and antibodies to the virus can persist for months after infection. ASFV can be diagnosed by virus isolation, ELISA, immunofluorescence or PCR. Clinical samples used for testing are lymph nodes, kidneys, spleen, lung, blood and serum. The simultaneous detection of both antigens and antibodies is recommended in order to identify the presence of potentially chronic infections that continue to spread the disease.
