Recently, Zhong Nanshan, winner of the "Order of the Republic", a famous respiratory disease expert and an academician of the Chinese Academy of Engineering, gave a lecture on "Frontiers and Challenges of Medicine" for Nankai University's "Famous Teachers Leading" general elective course. Zhong Nanshan, with the theme of "Science and Technology Guides the Fight Against the Epidemic, Bravely Climbs the Peak of Medicine, and Talks About Innovation with the Vast Number of Young People in Nankai", talks about scientific and technological innovation with young students from the current aspects of prevention and control of the new crown pneumonia epidemic and innovation, and also brings a heavy lesson of family and country feelings.
"In the fight against the virus, the highest human right is human life, a healthy life." Speaking about the prevention and control of the new crown pneumonia epidemic, Zhong Nanshan said, "The key issue in the prevention and control of the new crown epidemic is to minimize the transmission and case fatality rate. ”
The currently circulating Omikeron strain has mild symptoms, and some countries have promoted so-called "coexistence with the virus". In this regard, Zhong Nanshan said in light of the current epidemic situation, "At present, it is not applicable to China's complete opening up. For China, it should still adhere to dynamic zero clearance and gradually open up. ”
To do a good job in the prevention and control of the new crown pneumonia epidemic under the new situation, Zhong Nanshan proposed the "PROTECT" integration strategy. It is necessary to rely on the epidemic prediction model to guide prevention and control; strengthen the research and development of vaccination and universal vaccines to improve the prevention rate; implement the policy of "antigen screening and nucleic acid diagnosis"; accelerate the research and development of new crown drugs and antibodies; multidisciplinary rehabilitation intervention to reduce the risk of sequelae; realize the integrated prevention and control management of hospitals, communities and grass-roots levels; and change from disease-centered to health-centered.
At the end of the lecture, Zhong Nanshan put forward ardent expectations for the young students of Nankai University: "I hope that the students will enjoy the prosperous world, and when they live up to the prosperous world, you will not only have ideals, but also dreams; not only have requirements, but also pursue; not only have ambition, but also compete for courage; not only have enthusiasm, but also have passion." ”

On April 7 alone, Shanghai added 824 new locally confirmed cases and 20,398 local asymptomatic infected people, making the situation extremely severe.
World Health Organization experts have said that Omikeron is the latest strain of concern. Compared with the Delta strain, the severity of the disease caused by Omikerong is low, but it is still a dangerous virus, and infected people may have various symptoms of the disease, from asymptomatic infection to severe illness or even death, and patients with underlying diseases, advanced age, and unvaccinated patients may have more severe symptoms after infection, and people will still be admitted to hospital or even die because of infection with this variant strain.

Wu Zunyou, chief expert in epidemiology of the Chinese Center for Disease Control and Prevention, also said publicly recently: A study compared the case fatality rate and mortality rate of the relevant countries in the two time periods from August to October 2021 and from November to January 2022, and found that the case fatality rate during the epidemic of the Omiljung strain did decline, but the total number of deaths caused was higher than the number of deaths in the same period of the Delta strain epidemic. It can be said that the harm of the epidemic of the Omikejong strain is still serious, and it is not the "flu" that some people imagine.
At present, the Omiljung variant has a serious threat to special populations such as elderly patients and patients with severe underlying diseases. Among the infected people admitted to Jilin Province, there are severe and critically ill patients who need invasive ventilators to support breathing. Among the confirmed cases in Shanghai, some of them are asymptomatic infected people, and some are from mild and ordinary to severe. According to the Shanghai Municipal Health Commission, there is currently 1 severe case under treatment.
"The old man and the old man". Shanghai is an aging city. By the end of 2020, there were 5.3349 million registered elderly people over the age of 60 in Shanghai, accounting for 36.1% of the total registered population. The elderly are already susceptible groups, if you regard Omi kerong as a "big flu" and completely "lie flat", how many elderly people will suffer?
Chinese population base is large, the absolute number of elderly people is huge, coupled with the same absolute number of basic disease patients, once these two groups are infected on a large scale, it will not only bring a "run" risk to the health care system and other basic services, but also pose a huge threat to the lives of these two groups.
At present, the whole society must recognize the potential harm of Aumi kerong, and make great determination and efforts to control the epidemic as soon as possible, so that Omiljung will not cause sustained social transmission and widespread epidemic. This is exactly what China's fight against the epidemic should be to adhere to the concept of "people first, life first".
