Its spread faster than chickenpox among existing infectious diseases. Therefore, its spread is difficult to control, which has recently made all parts of the country expand the scale of detection and tracking in order to achieve the goal of dynamic clearing, and even adopt regional silence to stop the epidemic of the disease.
An important shift and evolution of the Omicron feature appeared
Zhang Wenhong said, Omicron’s symptoms did decrease, but there was a marked increase in some symptoms in the upper respiratory tract. There are two factors for the relief of Omicron’s symptoms. One is that he has been injected with vaccines, and the other is that Omicron’s virulence has also been reduced.
Zhang Wenhong said, “We are now seeing great challenges in this wave of Omicron, but we should also see more hope. The proportion of asymptomatic infections in the world has gradually increased, and the proportion of severe cases has further decreased. In other words, our challenges are actually not as high as expected. The main challenge is still from vulnerable groups. At the same time, effective drugs are gradually coming out both domestically and internationally, and the vaccine coverage rate is further improved and can prevent severe diseases. It will not end in the short term, we need more time, more patience, more courage, more wisdom and technology to overcome all this.”
It mentioned:
The epidemic situation is different from the past, and China’s prevention and control have achieved good results
In Omicron During the challenge, we all felt an unprecedented challenge
Omicron’s symptoms did decrease, but some symptoms in the upper respiratory tract showed a significant increase trend
There are two factors that reduce the symptoms of Omicron. One is because of the injection of the vaccine, and the other is that the virulence of Omicron is also reduced.

Vulnerable populations are the biggest challenge since the outbreak of Omicron
Vaccines are still an effective protective measure, especially for reducing severe illness and mortality
For future prevention and control, it is necessary to increase nucleic acid testing, vaccine coverage, non-drug intervention, drug treatment, early antiviral treatment, etc.
Maybe the new crown epidemic will not end in the short term, we need more time, more patience, more courage, more wisdom and technology to overcome all this.
What kind of global prevention and control model should we start in the future?
Zhang Wenhong said that China has summed up a lot of experience. The first experience is the expansion of nucleic acid testing. Increasing the strength of nucleic acid testing can also reduce the speed of virus transmission. But there is a requirement. We may have to do nucleic acid repeatedly for a long period of time, which of course will have a certain impact on our lives.
Secondly, vaccines are still an effective protective measure, especially for reducing severe illness and mortality. In addition, we are also investigating the potential for B cell receptors to reveal broad-spectrum vaccines. Because with the passage of vaccination time, the overall resistance level of the vaccine will continue to decline, and everyone is looking forward to the production of a broad-spectrum vaccine.
