farmers and breeders, especially after its outbreak in China
on August 3, 2018, which brought to light its severity that,
despite its slow spread, can elevate the mortality rate of
infected pigs to 100%, thus potentially resulting in enormous
economic and social impacts. The ASF spread quickly in
China and even extended to other neighboring countries
such as Vietnam, Mongolia, Cambodia, Lao PDR, Myanmar,
the Philippines, Korea, Indonesia, and Timor-Leste in less
than a year.
