Very contagious! Zhong Nanshan's latest reminder!

On December 23, at the 20th anniversary of the establishment of the Guangzhou Municipal Center for Disease Control and Prevention and the Public Health Summit Forum, Zhong Nanshan, the recipient of the Order of the Republic and an academician of the Chinese Academy of Engineering, made the latest judgment on the new coronavirus variant strain, Omicron.

Zhong Nanshan: The Aomi Kerong variant strain is very contagious

For the currently concerned Aomi Kerong variant, Zhong Nanshan said that the Delta variant took 2 months from discovery to become the mainstream variant, "Omicron was found in November, this section may increase, the New Cases in the United States have accounted for 72%, and the new cases in the United Kingdom on December 22 exceeded 100,000." ”

Zhong Nanshan said, "Aomi Kerong is now very sure: very contagious. How pathogenic and harmful is it? It is unclear whether the mortality rate will be higher, and we have a lot of work to do in this regard to epidemiological surveillance. Zhong Nanshan said that it is absolutely not to be taken lightly, and it is necessary to be highly vigilant.

Zhong Nanshan said that in this year's "5.21" new crown pneumonia epidemic, Guangzhou was able to reverse the rapid spread of the virus relatively quickly, and it was quickly clear that the cases all came from the same transmission chain.

"At that time, it was found that the Delta transmission coefficient can be as high as 1:4 to 1:5, and the disease control has done a lot of work, and we have changed a lot of concepts: expanding the concept of close connection, establishing a yellow code system, and screening work in large areas." After a lot of efforts, it took less than a month to quell the epidemic, and the number of cases stopped at more than 150. Zhong Nanshan said that according to the calculation of the laboratory model, if the development is allowed instead of taking positive measures, there will be 7.37 million infections in Guangzhou at that time, from which the strength and intensity of prevention and control can be seen.

Is China's vaccine useful for delta variants?

Zhong Nanshan said that the study of the "5.21" case found that after receiving two doses of inactivated vaccines produced in China, the prevention rate of delta variant infection was 59%, and the protection rate against severe disease was close to 100%. After the article was published, everyone increased the trust of China's vaccines.

Zhong Nanshan said that under China's group prevention and control strategy, after the new crown cases reached the peak of growth at the end of March last year, after 20 months, including imported cases, they only increased by more than 40,000, while in some countries it was 100,000 a day, "Which reflects different policies, different guiding ideologies, 'life first' guiding ideology and our prevention and control work are indispensable, and will write a heavy stroke in history!" ”

In the reform of the public health system, the state has established a disease prevention and control bureau, and various localities are also successively setting up disease control bureaus. Zhong Nanshan believes that the relationship between the CDC and the CDC should be handled well, and the CDC cannot simply serve as an institution for technical consultation and decision-making advice, but should give the CDC a greater say, and the CDC should be led by people who understand public health and "know how to do". "I have great hopes for the establishment of the CDC, and I hope that prevention and control work will become mainstream in the future."
