Since the cancellation of strict prevention and control, China has not detected any dangerous crown diseases.

Although China is responding to a tide of explosive cases, it is unlikely that the hope of a new mutant plant after Omikon is increasing.

This is in sharp contrast to the situation when the voucher organization is named for a new poison strain.At that time, people were particularly worried that the letters may soon be not enough if they named the Greek letters.A top scientific consultant in China said that there are almost no room for major mutation in some key structures of coronal virus.

Most of the changes that produce new variants occur in spiny protein.Casting protein is a virus part of the health cells, and its role is similar to the keys locked.According to Caixin report, Zeng Guang, former chief scientist of the China Disease Control and Prevention Center, said at a seminars on Thursday that the Speed protein of the coronal virus is the main force of mutation. Now the mutation of important amino acids on S -spiny protein is nearly saturated.

Future variants

Although Omikon may still develop or experience changes such as fusion with other coronary viruses, Zeng Guang said that he has a "cautious and optimistic" attitude towards the risk of future mutation.

Other scientists are not so optimistic, warning that even small changes may be devastating, and the emergence of mutations has always been random and contrary to expectations.

"The next variant will appear in a timely manner. Whether it is from China or other countries, it may not be from the Omikon family," said Eric Topol, the director of the Square Research Institute in Laralia, California.

In recent weeks, the global doubts about the new variants have been heating up again. As the virus has swept the country with the most population in China with amazing speed, countries have restricted Chinese tourists.

The Director -General of the WHO Tan Desai said two weeks ago that due to the lack of comprehensive information of China, other countries are taking measures that they think they will protect their population "understandable" and call on China to disclose more epidemic information.So that WHO can conduct comprehensive risk analysis.
