The first strains of the virus appeared in late January or early February 2020, while the mutant D614G suddenly replaced the original SARS-CoV-2 strain five months later as a "virus," the report said.
The bacterial strain is highly contagious and contagious, but does not cause more serious diseases, nor does it change the effectiveness of existing hospital treatments, vaccines, or public health preventive measures.
The second mutation was found in a mink breeding farm in Danzhou in late January 2020 or early February 2020.

According to preliminary studies, due to sudden changes in N501Y in the UK, this change is associated with high levels of the virus, suggesting that transmission capacity may increase, but there is no clear evidence that SARS can cause more serious disease or worse results.
