"My patient Mykola is one of such cases. He is a labor migrant, shuttling between Ukraine and the Czech Republic. He has already had this new variant identified by Britain. When it came to verifying this [strain], Ukraine was unable to identify this virus in mass testing. But people insured in EU countries could confirm the already mutated virus. Thus, I was able to confirm cases with the new coronavirus strain in Zakarpattia," he said.

The doctor added that the virus would be mutating very actively, and this is natural: "Why? Because it contains only one RNA, being the only carrier of genetic information."
