About 150 changes took place in new coronavirus since the beginning of the outbreak in China as National Science Review reported.

The scientists analyzed 103 publicly available genomes and found 149 changes in the virus strain; the majority of the changes took place recently.

It is established that the coronavirus split into two subtypes: L - the most frequent type (70%) and S – its share makes 30%.

L subtype was more often found at the early stage of the outbreak in Wuhan but its frequency reduced by early January.

According to the scientists, the interference of a human placed strong selective pressure on L subtype, which could be more aggressive and spread more quickly. Meanwhile, the relative incidence of S subtype increased due to less selective pressure.

“Our analysis suggests that S subtype, possibly, is the initial version of SARS-CoV-2,” the message said.

According to the experts, L subtype is more aggressive than S subtype and the interference of a human changed to relative incidence of L and S subtypes soon after the outbreak.

As we reported, the Finance Ministers of G7 countries (the U.S., Japan, Germany, the UK, France, Italy, and Canada) will discuss measures on the fight against coronavirus and its influence on the economy via video-conference.
