Recently, in response to citizens' concerns about the introduction of strains BQ.1 and XBB from Europe and the United States, Yuan Zheng'an, a member of the expert group of the Shanghai Epidemic Prevention and Control Leading Group Yuan Zheng'an said that the Omicron BQ.1 and XBB strains currently discovered in Shanghai have only been detected in a very small number of incoming quarantine personnel and have not yet caused local spread in society.
Over there in Shanghai, it doesn’t mean that XBB has not caused local spread. How come there is XBB transmitted from Shanghai in Chongqing? Moreover, people in the WeChat group talked about it very eloquently, such as how it is 10 times more contagious than Okmiron, how it can cause diarrhea and kill people, and send them to the emergency center.
checked on the Internet that XBB is a mutated strain of Oak Miron. There is no scientific evidence to prove that XBB and its substrain XBB.1.5 have the ability to attack the cardiovascular and cerebrovascular and digestive systems . The threat of XBB.1.5 lies in its strong immune evasion ability, but it has not evolved "specific functions" that can cause other serious symptoms. According to CCTV website news, experts said that XBB may spread faster. XBB, BQ.1, and BQ.1.1 are similar in pathogenicity to previous strains, but their immune evasion ability has increased. Therefore, the virus caused by may spread faster than before.
