An animal study showed that the ability of the Omickron subtype strain BQ.1.1 to cause symptoms is comparable or lower than that of the early novel coronavirus variant.
According to the Japan Broadcasting Association (NHK), the study was published by a G2P-Japan research team led by Professor Sato Kei of the Institute of Medical Sciences of the University of Tokyo. This paper has not yet been formally peer-reviewed.
study report points out that when cells are infected with the BQ.1.1 strain, their ability to destroy surrounding cells is 2.4 times higher than that of the current dominant strain BA.5 in Japan.
Kei Sato said that although the research results may not be directly applicable to humans, the pathogenicity of the latest variant of the new coronavirus has not increased, which is good news. But he added that as the virus is still very transmissible, anti-infection measures should continue to be taken.
Recently, news circulated on social media that a new mutant strain called BQ.1.1 has appeared. The strain has high infectivity and mortality rate. It is called "hellhound" by netizens and has "killed crazy" in Japan.
In fact, this new coronavirus mutant strain called BQ.1.1 appeared as early as July and was first discovered in Nigeria . According to Reuters , according to the information provided by World Health Organization , the BQ.1 series strains (labeled as BQ.1*) and their subtype strains BQ.1.1 are members of more than 300 Omickron mutation families currently popular around the world. Nearly 95% of these members are "direct descendants" of Omickron variant BA.5.
In addition, it is reported that since the beginning of winter, Japan has experienced a new wave of epidemics, with the number of new deaths per million people increasing, but there is no evidence that the increase in deaths is directly related to the emergence of the BQ.1 and BQ.1.1 strains. At present, there has not been a large-scale BQ.1.1 epidemic in Japan, and the dominant strain is still BA.5.
