Zhang Wenhong: It's A Foregone Conclusion To Go Out Of The Epidemic Situation...

On December 17, at the 2022 Sino US High end Forum on Clinical Microbiology and Infectiology, Professor Zhang Wenhong, Director of the Infection Department of the National Infectious Diseases Medical Center and Huashan Hospital affiliated to Fudan University, said that at the moment when the peak of infection is coming at this stage, the elderly should be well protected.

"If the elderly have not been vaccinated, their mobility should be reduced, and they must wear masks when coming out. When meeting the elderly, they should wear masks again. Finally, we hope that the elderly can be vaccinated and have better drugs to protect them."

"When the COVID-19 emerged this time, we knew that the virus spread far faster than the influenza virus, and people generally have no immunity to this virus." Zhang Wenhong introduced that human beings never achieve the goal of controlling infectious diseases by eliminating a species. Therefore, since the birth of influenza in the world, it has gradually reached a balance with our human immune system. With our human vaccination and universal infection, it will maintain a certain stability with infectious diseases. "

Zhang Wenhong said that COVID-19 also faces the same situation. "It can be seen from various studies at present that after vaccination, we have a great pressure on the evolution of the virus, which has greatly reduced the number of virus evolution after vaccination. At last, what we see today is the final victory of the Omicron strain. This strain has a certain escape effect on human immunity, and its R0 value is close to the level of 16-18. It jumped out of the Omicron strain family and was born again A strain that spreads faster is now very difficult. "

Zhang Wenhong said: "From the data of Shanghai, the virulence of the Omicron strain has shown a significant trend of decreasing, but its aggressiveness to vulnerable people still exists. Especially for people over 80 years old, they are also the main severe patients. In addition to age, chronic kidney disease, hypertension and some neurological diseases are the main causes of the disease of vulnerable people. Most of the deaths or severe patients It usually happens among people who have not been vaccinated. Therefore, vaccination is critical to protect vulnerable populations. "

"At present, the focus of our work is to fully protect the elderly. Specifically, we should do three things well. First, we should give them adequate drug treatment once they are infected with symptoms; second, we should advise them to fully vaccinate; third, we should form a reverse protection for them during the pandemic to prevent viruses from entering their living space."

Zhang Wenhong said that he hoped that more new vaccines against Omicron would come into the market as soon as possible, which would also be of great value in preventing the infection of Omicron among vulnerable people. "Nevertheless, vaccination of existing vaccines still effectively helps us form a certain immune barrier against Omikjon, and ultimately enables us to win this battle.".
