The mutant strain in this round of epidemic in Sanya was detected for the first time in China. Under what circumstances will the poisoned strain mutate?

Sanya reported 59 newly confirmed cases and asymptomatic infection cases 1 case. , has been sent to the designated hospital for isolation treatment, and the situation is stable. Sanya? 08.0 1? The epidemic was caused by novel coronavirus Omicron variety BA.5. 1.3. BA.5. 1.3 was detected for the first time in China. The epidemic situation was caused by overseas import, and the fishing port in Yazhou Center was the source of the epidemic situation. Most infected people are related to fishing ports, fishing boats, fishermen and fish markets. The transmission chain radiates from the fishing port in Yazhou Center. The epidemic situation is on the rise, and there is a risk of community transmission in urban areas. 740,000 nucleic acid samples were screened for health in Sanya.

The total number of regional nucleic acid samples in the city is 6.5438+0.69 million, and the detection work is carried out day by day. Sanya has controlled the personnel involved in the abnormal mixed inspection results, and carried out the recheck of single sampling, and relevant information will be announced in time. Poison is a very simple creature, which generally consists of only two substances: protein shell and nucleic acid wrapped in it. It has no independent life system and can only live in living cells. When COVID-19 enters the cell and replicates rapidly, it means that the RNA of the virus replicates rapidly, and mistakes are inevitable in this process, so it is easy to mutate. And constant mutation can help the virus escape antibody recognition.

As a part of virus evolution, COVID-19 mutation is not a new topic in the scientific community. These mutations are unlikely to lead to the failure of the current vaccine research and development, because the COVID-19 vaccine under development has enough gene sites to produce immune protection, and the mutation of many gene sites does not necessarily invalidate the vaccine. Vaccine researchers should pay attention to the progress of novel coronavirus mutation and explore the biological significance of these gene mutations, so as to grasp the design of candidate vaccines more comprehensively in vaccine research and development and ensure that sufficient immune protection can be induced. Through bioinformatics or big data mining, we can immediately find the target antigen, pathogenesis or receptor enjoyed by * *, thus quickly guiding vaccine improvement.
