The new crown Omickron mutant strain has mutated again. The first BF.7 local new crown infection has occurred in Hohhot, my country, and has triggered a local epidemic.
On October 6, Jimu News reporters noticed that as early as September 23, the British Coventry Telegraph reported that the new variant BF.7 is spreading rapidly in Belgium, Germany, France, Denmark and the United States. WHO issued a warning that BF.7 may become the mainstream globally within a few weeks.

BF.7 new crown infection has appeared in my country
According to the previous report of Health Times , on September 28, a local new crown infection was reported in Hohhot, Inner Mongolia Autonomous Region. After national genetic sequencing test, the case belongs to the evolutionary branch of the new crown virus Omickron variant strain BF.7, which is the first time this branch has caused a local epidemic in China. As of October 3, more than 500 cases of infection with the mutant strain in Inner Mongolia Autonomous Region have been reported in 6 days.
Jimu News reporters noticed that the number of infections in Inner Mongolia Autonomous Region is still increasing. From September 28 to October 5, the Inner Mongolia Autonomous Region reported a total of 1,258 local infections for eight consecutive days. What are the characteristics of the new mutant strain BF.7 in
? Wang Yuge, a U.S. vaccine research scholar, , research scholar, and doctor of immunology at the National Institutes of Health, told the People's Daily Health Client reporter that BF.7 is essentially an OmicronBA.2 lineage virus. From BA.2 to BA.5 to BF.7, new mutant strains are constantly "inverting", the virus spreads continuously, and the ability to evade epidemics is becoming stronger and stronger.
Shaanxi Center for Disease Control and Prevention interpreted the BF.7 variant strain. The symptoms of this variant after infection include high fever, persistent cough, physical pain, headache, sore throat, altered smell and loss of appetite.
"Patients infected with BA.5 are still at risk of being infected with BF.7." Wang Yuge further explained that BF.7 adds the receptor-binding domain RBD mutation R346T on the basis of BA.4/5, which can further escape the neutralizing antibodies induced by BA.5 infection. Therefore, it is likely to become a popular mutant strain this fall and winter.
has previously spread rapidly in many countries around the world
According to the Coventry Telegraph on September 23, the detected new variant BF.7 is spreading rapidly in several countries, and in some countries it now accounts for a quarter of new cases.
According to statistics, the new variant BF.7 accounts for 25% of the new coronavirus cases in Belgium and 10% of the cases in Germany, France and Denmark. To date, the UK has seen hundreds of cases of new variant BF.7. In the United States, new cases are also increasing rapidly in just a few days, and it is more transmissible than BA.5.
Statistics from the US Centers for Disease Control and Prevention show that the incidence of the new variant BF.7 in the country has doubled in the past two weeks, from 0.8% to 1.7%. The website said this proves that the U.S. government’s concerns about the future epidemic are justified.
"From Alpha to Beta to Gamma to Delta, and then to Omicron, it has been a while since we may be complacent and feel that the new crown is over." An expert in the Department of Medicine at Johns Hopkins University admitted that the new crown will not disappear. He analyzed the growth of variants in different countries and believed that "BF.7 is gaining a foothold."
The World Health Organization also issued a warning that BF.7 is spreading around the world and "may become mainstream within a few weeks."
The current anti-COVID plan is still effective
More than experts said that the current anti-COVID plan is still effective.
WHO The priority review expert of the new crown vaccine and deputy director of the Jiangsu Provincial Center for Disease Control and Prevention Zhu Fengcai told the People's Daily Health Client reporter that the breakthrough infection has always existed, and the situation of re-infection of the new crown also exists. At present, the vaccine still has protective effect. Moreover, although the transmission power of BF.7 is enhanced, most of them are asymptomatic and mild patients.
is not only a vaccine, but the new coronavirus drug should also be effective against the mutant strain BF.7. Academician of the Chinese Academy of Engineering , and Director of the Institute of Drug Research of the Chinese Academy of Medical Sciences Jiang Jiandong told the People's Daily Health Client reporter that the main target of the new coronavirus small molecule drug is viral replicase, and at present, no mutations were found in the Omickron binding target site, so the impact on small molecule drugs should be small. Azvdin is effective for the current epidemic strain from the collected real world clinical data.
