報告摘要:

African swine fever is caused by a highly-resistant Asfivirus, documented in Kenya from

around 1907. In Africa, it causes usually inapparent infections in warthogs, bush pigs and

forest hogs, and is transmitted by the soft rick, Ornithodoros, which is probably the virus’

natural host. Domestic pigs, however, succumb to clinical disease, signs including fever, loss

of appetite, abortions, internal bleeding, with haemorrhages visible on the ears and flanks.

Severe strains of the virus are generally fatal, death occurring within 10 days, whereas mild

strains may not be associated with typical clinical signs. In 2007, the virus spread from eastern

Africa into the Caucasus, through Russia, reaching the northern Russian Federation in 2011.

In Russia and Europe, European wild boar, in addition to domestic pigs, can be infected with

the clinical disease, transmission occurring either directly between the two species, or

indirectly by fomites (e.g., hunters, vehicles, meat products, and kitchen waste), whereas ticks

do not currently appear to have a role in transmission. Between 2011 and 2017, the disease

spread westwards into the European Union, and eastwards, major outbreaks occurring in

China in 2018. The disease continues to spread in 2019, with, in Europe, recent outbreaks in

Bulgaria, Poland and Slovakia, and, in Asia, outbreaks across China and in Cambodia, Korea,

Laos, Mongolia and Vietnam. Some predictions suggest that China could lose half of its pig

herd from the disease. There is no vaccine against African swine fever. Prevention and

control therefore involve rapid slaughtering of affected animals; cleansing and disinfection;

biosecurity; movement restrictions; source and spread tracing; and zonal surveillance.

The emergence of mild strains raises the prospect of the development of attenuated vaccines.
