Since the presence of African Swine Fever was first reported in China in August 2018, its expansion in Asia and the Pacific area has been steadily increasing. The virus has become a serious problem as this region covers more than 60 percent of the world’s domestic pig population. According to the data of the World Organisation for Animal Health (OIE), in the second quarter of 2020, 56% of all domestic pig deaths worldwide due to African Swine Fever (ASF) were concentrated in Asia, and this figure increases to 82%, the equivalent of 6.7 million animals, if deaths produced since 2016 are counted.
