The number of confirmed diagnoses in Japan has dropped sharply, and the study finds that the new coronavirus dies after a new mutation-IT & Health
Entering October, the number of confirmed cases of the new crown in Japan unexpectedly began to drop sharply. Japan’s epidemic prevention and control measures are not stronger than before, but are relaxing. This abnormal phenomenon is likely to be related to the mutation of the virus. Japanese researchers found The new mutation of the new coronavirus may cause the virus to self-death.
According to a report from Kyodo News on the 31st, the research team from Japan’s National Institute of Genetics and Niigata University recently published the latest research. Studies have found that in the genome of the delta mutant strain, an enzyme called “nsp14” has mutated, causing the virus to fail to complete repair in time, leading to the virus’s self-extinction.
In the process of rapid virus replication and spread, the genome sometimes undergoes wrong mutations, which is also one of the main causes of disease.
At this time, “nsp14” is generally responsible for repairing. However, if the repair is not timely and too many mutations are accumulated, the virus may not be able to reproduce.
In addition, the research team speculated that an enzyme called “APOBEC” changed “nsp14”. It is said that in East Asia and Oceania, this enzyme is particularly active in many people.
