(Fighting against New Coronary Pneumonia) Zhong Nanshan: Virus mutations increase infectivity, suggesting that overseas students spend the holidays in situ

China News Service, Guangzhou, January 31 (Cai Minjie) “Guangzhou laboratory technology helps grassroots epidemics The “Walk of Miles Prevention and Control” event was held in Guangzhou on the 31st. Zhong Nanshan, an academician of the Chinese Academy of Engineering, answered questions related to epidemic prevention during the Spring Festival.

For the mutation of the new coronavirus, the first is to closely track, and the second is to observe the effectiveness of the vaccine. Zhong Nanshan said that the most critical mutation of the virus now occurs in the receptor binding site of the spike protein. “This easily opens the door for the virus to infect people. The virus can easily invade the body and cause disease. This is a new coronavirus infection. The reason why sex becomes stronger”.

Zhong Nanshan emphasized that on the one hand, it is necessary to track the mutated virus, and on the other hand, it must also consider what kind of virus strain is used to make the vaccine after the virus mutates. “Is it possible that the virulence of the new coronavirus becomes like influenza, which changes every year?” Zhong Nanshan said that the influenza vaccine used every year is based on the virus strain predicted by the World Health Organization. “Whether the new coronavirus will be like this in the future, we need to closely track it. The current virus mutation is worth noting, and the effectiveness of the vaccine must be observed. Related research is still being done.”

Zhong Nanshan said that the current Chinese new crown pneumonia The climax of the epidemic has passed, and the situation of the recovered patients has received attention.

Recently, in some areas, the nucleic acid test turned positive after a confirmed case of new coronary pneumonia recovered. In this regard, Zhong Nanshan does not believe that the cases of transfer to Yang are very threatening and highly contagious. “Of course, this does require a longer period of observation. Maybe these cases have residues of nucleic acid fragments, but the residues of nucleic acid fragments do not mean there are Live virus, it is rare to see that the nucleic acid turns positive and will infect others. If you find this situation, you need to continue to take more tests. Of course, you must be properly isolated, but you don’t have to treat him as a real patient.”

Zhong Nanshan emphasized that for recovered patients, we must not only pay attention to their physical recovery, but also pay attention to their mental health. “At present, we are not doing enough in this area.”

“For overseas students, it’s complicated to not go home for the holidays, everyone can understand.” Zhong Nanshan said, but in order to prevent and control the development of the epidemic, it is recommended to celebrate the festival in situ or through video. At the same time, it is very important for the relevant departments to do a good job, to give some greetings, send messages and even condolences.

Zhong Nanshan pointed out that Chinese overseas students need to wear masks. “If there is a chance to get vaccinations, they are in favor of vaccination. I wish overseas students a happy Chinese New Year and better results in the Year of the Ox.” (End)< /p>
