BA.5.2 virus strain is prevalent in Omicron and spreads rapidly. The toxicity of the virus in this epidemic is relatively weakened. There are no severe patients in this epidemic, most of them are mild, so you don't have to panic. According to reports, the current epidemic situation is indeed severe and complicated. What else happened this year? Local time1October 27th 165438+, the research team of Rome Children's Hospital released the picture of the world's first new mutant strain Omicron. Comparison of Spike Protein Mutations between Delta Strain and Omicron Strain Tu Tu Source: Rome Children's Hospital Picture shows, what is this?
On April 5th, the press conference on epidemic prevention and control in Shanghai informed that the number of newly infected people in Shanghai broke through 10000 for the first time yesterday, reaching a total of 13354. Since March, more than 73,000 cases of positive infection have been reported in this round of epidemic in Shanghai. Omicron mutant virus will be discussed later. Since March 2022, Omicron strains have been imported into Shanghai from abroad. Due to the strong confidentiality, coupled with Shanghai's high population density and high mobility, it spread widely in the city without knowing it. At this time, what about comprehensive isolation prevention and control and "dynamic clearing"?
Japanese Epidemic Alert At present, the COVID-19 mutant strain with the fastest spread rate in the world is still the Omicron subtype strain BA.2, which has once again set off a wave of infection. On April 1 1, the overseas network quoted the Japanese media "Nikkei Modern" as saying that due to the Omicron subtype virus strain BA.2 and so on. At present, human understanding of these new strains is still limited, but the scientific community recognizes that these new strains spread faster, more infectious and more concealed. All these features make it more difficult to remove them dynamically, which will be introduced later.
1, Omicron strain replaces Delta strain: From the number of cases with COVID-19 mutant strain in New York State, it can be seen that the number of cases of Delta strain has dropped to a very low level at the end of 202 1, and Omicron has replaced Delta in the dominant position. From June 2022 1, what about 99? The second bad news is that a new mutant strain BA.5 has appeared in this epidemic in Shanghai. It is understood that this new mutant is not only highly contagious, but also very concealed, so Shanghai is now under great pressure to fight the epidemic. Because Shanghai is not only responsible for the wind of foreign imports, but also says.
