Zhang Wenhong: I still believe that this may be the last winter of the new crown pandemic

On the 15th, Zhang Wenhong, director of the National Center for Infectious Diseases And director of the Department of Infectious Diseases of Huashan Hospital affiliated to Fudan University, was interviewed by CCTV News "Relativity" to answer questions about Shanghai's "minimum medium-risk area" and the Omikerong variant.

Zhang Wenhong: The division of "minimum medium-risk areas" has two prerequisites

The communication chain is clearly visible and big data tracking is in place

On the 13th, Shanghai reported 2 locally confirmed cases and 3 local asymptomatic infected people, all of which were associated with a case of asymptomatic infection imported from abroad reported by the city on the 11th.

Among the above 5 infected people, 3 are the service staff of a milk tea shop at No. 228 Yuyuan Road, Jing'an District. The milk tea shop is listed as a medium-risk area and is also called "the minimum medium-risk area" by netizens.

Zhang Wenhong told CCTV News "Theory of Relativity" reporter Zhuang Shengchun that there are two main reasons for this "accurate division": one is that the current round of epidemic in Shanghai is very early and the transmission chain is clearly visible; the other is that big data tracking is in place, and most people in the surrounding neighborhoods have not entered this milk tea shop. If widespread community transmission has already occurred, the division of risk zones will need to be adjusted accordingly. "Shanghai's precise prevention and control, as long as it involves risk areas, must be in place, and at the same time, it must not be blindly expanded."

Zhang Wenhong: The toxicity of Omike rong cannot be ignored

The import risk in the next six months should still be very high

Recently, the domestic epidemic situation has been sporadic at many points, and according to the published circulation situation, some of them have come from relatively independent overseas imports. Zhang Wenhong said, "In the next six months, the import risk should still be very high. ”

In Zhang Wenhong's view, the severe illness of Omi Kerong is declining, but the toxicity cannot be ignored. His team made a wide-ranging comparison of the Ami keron and Delta viruses, the former causing no less fever than the latter. "Judging from the latest calculated case fatality rate in the United States, if nothing is really done, it will have very serious consequences." Speaking about China's experience in fighting the epidemic, Zhang Wenhong said with confidence: "If we are fast enough and the epidemic prevention runs ahead of the virus, we can win every victory of dynamic zero clearance." ”

Zhang Wenhong: The COVID-19 vaccine has been effective in reducing severe illness and mortality

The global spread of COVID-19 has once again sparked public discussion about the role of vaccines. Zhang Wenhong told reporters that studies on mutants have shown that the new crown vaccine has a significant effect on reducing severe illness and mortality, especially the third dose of vaccine can increase antibody levels by dozens of times. As for the fourth stitch, he thinks it is too early to say, "There is no need to be so anxious now, and we can have more international experience for us to use." ”

"This could be the last 'winter'"

"I still have a lot of confidence that the COVID-19 pandemic will end at the end of this year." On the 15th, Zhang Wenhong, director of the National Center for Infectious Diseases And director of the Department of Infectious Diseases at Huashan Hospital affiliated to Fudan University, said that in principle, after the next year, whether it is the level of herd immunity, or the immune barrier established through vaccines, or the listing of new crown treatment drugs, it means that "this may be the last 'cold winter'".

Whether it's Delta or Opmiqueron, it's just that the virus has mutated. Zhang Wenhong has said that if the new crown regroups with other coronaviruses, the situation may be worse. In the connection, Zhang Wenhong further explained: "So far, this is still a very low probability event. I believe that the experience we have accumulated in the process of dealing with COVID-19, no matter what kind of mutation the virus will occur in the future, we humans will still be able to cope with it. ”

In the video connection, reporter Zhuang Shengchun also raised the question of netizens to Zhang Wenhong: When the girl said that she was afraid that she would not be able to return home because of the epidemic this year, how to comfort her and cheer her up?

"Tell her it's going to be the last winter, and we'll cheer up." We believe in China, we believe in the world, there are so many people working together, we get through this cold winter, next year's Spring Festival will no longer be so cold. ”

When asked about his New Year's wishes, Zhang Wenhong replied: "I hope that next spring festival, every family can be reunited, and every pair of long-distance lovers can hug together." ”
