In recent days, the number of cases has continued to spike in many countries. What’s more, in some countries that have been successful in containing the epidemic, the number of infections is once again on the rise. Moreover, several countries have reported the discovery of new mutations of the coronavirus.
To date, a total of four countries have notified a new mutated strain: Japan, Malaysia, India and Vietnam. Japan discovered a new coronavirus with a novel gene sequence; Malaysia discovered a mutated strain that spreads 10 times faster; India discovered 73 new variants of a new coronavirus strain; and Vietnam discovered a new strain of a new coronavirus.
Why do the coronaviruses mutate so easily?
Because they are RNA viruses. RNA viruses do not have a complex life system, and they do not have an error correction mechanism, so their genetic stability is much less stable than human genes, while RNA viruses mutate faster. The replication process of RNA is for quantity rather than “quality”, and constant mutation can also help it evade the recognition of antibodies.
