Genotype I African swine fever virus isolated in China

Two non-haemadsorbing genotype I African swine fever virus isolates (HeN/ZZ-P1/21 & SD/DY-I/21) have been discovered in pig farms in Henan & Shandong provinces, China – posing a potential problem for control and prevention of ASF. The emergence of genotype I virus is in addition to the Georgia-07-like genotype II  ASFV with high virulence that has been prevalent in China since 2018. The isolation of the strains, including animal studies with live ASFVs were performed in the enhanced biosafety level 3 (P3+) facilities in the Harbin Veterinary Research Institute (HVRI) of the Chinese Academy of Agricultural Sciences (CAAS).
