Chinese scientists have confirmed that milder African swine fever virus (ASFv) mutations are circulating in China.
These conclusions were drawn by scientists at the Harbin Veterinary Research Institute. The study was published in the journal Life Sciences, a publication of Science China and follows previous reports on ASFv mutations emerging in China.
In their article, the researchers wrote: “The emergence of less virulent natural mutants further complicates the early diagnosis of ASF and creates new challenges for the control of ASF. They added, “Considering the huge pig population in China and an endemic period of more over the past 2 years, it is not surprising to find complex genetic diversity among ASFs on the ground in China. “

ASFv surveillance in 7 Chinese provinces
Scientists carried out surveillance in 7 Chinese provinces from June to December 2020. They collected 3,660 samples from farms, slaughterhouses and disposal plants in Hebei, Heilongjiang, Hubei, Inner Mongolia, Jilin, Liaoning and Shanxi. They isolated and …
