Since the beginning of 2020, the new crown epidemic broke out. Until 2022, the global epidemic is still very severe, and the domestic epidemic is intermittent. The new coronavirus continues to mutate and challenge people. After Omickron , new crown mutated again - BF.7. This type of mutant strain may have stronger immune escape ability.
Omickron's new mutation strain - BF.7
World Health Organization issued a warning that BF.7 is spreading around the world and "may become mainstream within a few weeks." my country has reported a local epidemic in the BF.7 branch. What are the characteristics of the new variant BF.7? What should we do in the face of new mutant strains? How popular is
BF.7?
BF.7 is the abbreviation of BA.5.2.1.7. It is considered to be the third generation subtype derived from the Omickron BA.5 variant, with the BA.2.75 variant intersected. US Centers for Disease Control and Prevention COVID-19 data monitoring found that since the start of monitoring, the percentage of strains of BF.7 has increased to 4.6% in the short term, becoming the third largest mutant strain in the United States to detect the new coronavirus. In addition, in Europe, BF.7 accounts for 25% of the infected people in Belgium ; Germany, France and Denmark account for about 10%.
BF.7 is very popular and is a type of Omickron mutant strain. It spreads faster and will pose a huge threat to people's lives and health. What are the symptoms after
BF.7 infection? The symptoms shown after infection of the
BF.7 variant strain are similar to those after infection of the early subtype variant of the new crown Omickron. People who are infected may experience high fever, persistent cough, physical pain, headache, sore throat, altered smell and loss of appetite. What should we do with
?
The epidemic situation is still very serious, and infection cases have been reported in various places. Faced with the new mutation of the new crown Omickron, we must first maintain a calm and calm heart and not be scared by it.
Secondly, we should actively cooperate with all prevention and control measures at this stage, do nucleic acid on time, and do not miss the test. Through all nucleic acids, all localities can grasp the changes in the epidemic in a timely manner, and better introduce relevant policies to ensure the sustained and healthy development of epidemic prevention and control work. In addition, all people should pay attention to personal protection and personal hygiene, including wearing masks, maintaining social distance, washing hands frequently, and ventilation. Although the Omickron mutant strain BF.7 is more contagious than the existing mutant strain, wearing a mask is still a very effective personal protection measure.
Epidemic prevention and control I am the first to
In autumn and winter, the weather turns cooler, and the new coronavirus can survive in cold weather for a long time. Therefore, we must pay more attention to personal protection, and it is not only the new coronavirus pneumonia, but also the high incidence season for many respiratory infectious diseases. Scientific wearing of masks can effectively reduce the risk of transmission, prevent the spread of the epidemic, and reduce cross-infection. When socializing, insist on washing hands frequently, ventilating frequently before going out, dividing meals when eating, using public chopsticks, and maintaining a social distance of "1 meter line".
Although the new crown is still there, people's hearts will never fade. No matter how many times the new crown will mutate, I believe that one day we will receive a message like this: Today, the global new crown epidemic has ended.
I believe that the epidemic will eventually dissipate, and I wait for the spring to bloom. [Send Heart][Send Heart]
The day the epidemic has subsided, spring is warm and flowers bloom
