The British Health and Safety Administration reported earlier this month that the transmission of these strains may be stronger than BA.5.BA.5 is the most infectious coronal virus strain known to date.European officials said that there is no evidence to show that BQ.1's condition is more serious than the currently spreading BA.4 and BA.5, but according to the results of laboratory research in Asian countries, it may avoid the immune protection of the vaccine.

(Washington / Bangalore Comprehensive Electricity) The latest mutant strains BQ.1 and BQ.1.1 are spreading in the United States and Europe, which has attracted attention.The number of cases caused by these two closely related strains increased rapidly in the United States, and the European side also predicts that they will become the main strain that leads to crown disease within one month.

According to the data released by the US Disease Control and Prevention Center on Friday (October 21), cases caused by BQ.1 and BQ.1.1 are currently accounting for 16.6%of the cases of crown diseases in the United States, almost twice the last week's last weekEssenceIt was estimated to be 9.4%last week.

The European Disease Prevention and Control Center (ECDC) warned that these recent mutant strains may become the main virus strains in Europe to early December, leading to rising new cases in Europe.

The two new variants belong to the "descendant" American winter epidemic may be urgent

These two variants are the "descendants" of the BA.5 of the Omikon subtype. In Europe and the United States, both European and American regulators have recently approved the vaccine addition agent for BA.5.

Poland, a virusist and vaccine researcher at Mayo Clinic, said: "These variants (BQ.1 and BQ.1.1) are likely to lead to a very serious cases in the United States this winter, Europe and Europe and Europe andBritain has begun to happen. "

The British Health and Safety Administration reported earlier this month that the transmission of these strains may be stronger than BA.5.BA.5 is the most infectious coronal virus strain known to date.

However, European officials said that there is no evidence to show that the condition caused by BQ.1 is more serious than the currently spreading BA.4 and BA.5, but according to the results of laboratory research in Asian countries, it may avoid vaccines.Immune protection.

New poison strains are good at avoiding avoiding epidemic antibodies.

The US President ’s Chief Medical Consultant, Foch, also said in the news program of Columbia Broadcasting Corporation on Friday that BQ.1 and BQ.1.1 both have" the characteristics of danger to avoid some intervention measures. "

The infectious disease expert pointed out that BQ.1.1 is particularly good at avoiding immune antibodies obtained by infection or vaccination before infection.

He said that if they really spread quickly, they may reverse the current trend of the number of confirmed cases, hospitalizations and deaths in the country.He urged people not to relax their vigilance.

A recent research report published by scientists in Peking University in China pointed out that BQ.1.1's ability to evade antibodies "far exceeds" BA.5.This study has not yet been reviewed by the peers and found that BQ.1.1 can escape the immune protection caused by infection with BA.5B and using some antiviral drugs.

The World Health Organization (WHO) data released this week, BQ.1.1 has been spread in at least 29 countries, but it has not been recorded locally.According to the data of the Ministry of Health on October 17, in the local crown disease cases that were genetically sorted last month, 77 % were infected with BA.5 strains, 16 % infected BA.2 and the same spectrum strain (including BA.2.75), 6%infected XBB strains, 1%infected BA.4.
