Small-scale pig farms with weak biosecurity systems account for a large proportion of China's pork production, which may be one reason for the rapid spread of ASF in China. In 2019, Mongolia reported the first ASF outbreak in January, followed by nine other Asian countries, including Vietnam, Cambodia, north Korea, Laos, Philippine, Myanmar, Russia, South Korea and Timor-Leste, 3 Lu G.
