Chinese scientists found traces of the RmYN02 virus, which is a close relative of COVID-19, in bats from Yunnan province, which confirms the natural evolution of the causative agent of the coronavirus SARS-CoV-2. About this newspaper South China Morning Post.
Researchers studied samples of the lungs, liver, feces, and flying membranes of 200 individuals. After analyzing these fragments, scientists isolated the genome of a virus called RmYN02 from them. Its structure was similar to SARS-CoV-2.
One of the authors of the work, the head of the Institute of Pathogen Biology at Shandong First Medical University, Weifeng Shi, explained that this experiment confirms the natural appearance of inserts in the genome of coronavirus and that they first appeared in animal beta coronaviruses.
On December 31, 2019, Chinese authorities announced an outbreak of pneumonia in Wuhan. The causative agent of the disease is a new type of coronavirus SARS-CoV-2, which causes the disease COVID-19.
