Since 2020, the new crown pneumonia epidemic has raged in many countries around the world, becoming the biggest public health crisis since World War II. Although 2020 has passed, the global epidemic situation is still not optimistic. According to data from Johns Hopkins University in the United States, as of 6:22 on February 1, Beijing time, the cumulative number of confirmed cases of new crowns worldwide exceeded 102 million, and more than 2.22 million people died from the new crown.
According to Japan’s Kyodo News Agency on January 31, citing an investigation by some British universities and other institutions, the three highly infectious new coronaviruses found in the United Kingdom, South Africa, and Brazil have spread to at least 77 countries and regions around the world. Japanese media said that the effect of existing vaccines on the mutated new coronavirus is still unclear, and it may not prevent the increase in deaths and severe patients even if vaccination.
For a period of time, overseas epidemics have also had a certain degree of impact on my country, and in the recent period, it has been more aggressive. But even so, China’s response to the epidemic is still very timely. A few days ago, Academician Zhong Nanshan had the latest reminder of the current epidemic, and Chinese people must pay attention to it.
According to the news from China Youth Network on January 31, Academician Zhong Nanshan said at the “Guangzhou Laboratory Science and Technology Helps Grassroots Epidemic Prevention and Control” event held that day, the most critical mutation of the virus now occurs in the receptor binding of the spike protein. The site, which easily makes the door for the virus to infect people wider, making it easy for the virus to invade the body and cause disease, which is the reason why the new coronavirus becomes more infectious.
Academician Zhong Nanshan pointed out that on the one hand, we have to track the mutated virus, and we must also consider what kind of virus strain will be used for vaccine after the virus mutates. Is it possible that the toxicity of the new coronavirus will gradually change, and will it become flu-like, changing every year? Every year we use the flu vaccine, the WHO predicts the three possible virus strains next year, and then we will make the vaccine. In the future, whether the new crown virus will be like this, we need to closely track it.
Zhong Nanshan also expressed his attitude towards the current global epidemic situation. Zhong Nanshan said that there are still two countries that are still high, the United States and Russia, and the others have begun to decline. Since each country has adopted relatively strong measures, it is actively controlled while actively increasing vaccination. It may only be around March, I think it will start to decline.
