African swine fever, first identified in China in 2018, has spread widely in the country and to several neighboring countries, including Cambodia, Mongolia, and Vietnam. Officials estimate that more than 1 million pigs have been culled in an attempt to control the outbreak. Annual pork production is also expected to decline significantly in 2019, which may lead to more imports. There are concerns that reporting of local outbreaks within China has been slow, which may make control of the disease more difficult.

More about the current status of the African swine fever outbreak in China is available in the New York Times.

More details on African swine fever are also available in the Merck Veterinary Manual.
