According to Xinhua News Agency reported on July 18, the new subtype BA.5 and BA.4 of the new crown virus Omircong strains accelerated the spread in the United States, setting off a new wave of infection. American experts point out that these two new subtypes are more contagious than previous strains, stronger immune escape ability, and bring huge challenges to the prevention and control of epidemic. The current prevention and control measures in the United States may face a more severe situation in summer and autumn.
According to data from the US Centers for Disease Control and Prevention, BA.5 has become a strain that dominates the United States; recently, the United States has an average daily increase in new crowns in the United States. About 5800 cases. However, some experts pointed out that the number of actual cases in the United States may be much higher than official statistics. Some mild groups do not test at all, and some people have not been included in the statistics of the results of the test at home.
Eric Toppol, a geneticist at the Syllps Institute in the United States, believes that the number of newly confirmed cases in the United States may be as high as 1 million. He said that BA.5 has evolved sharply from its "predecessor" subtype, and has obtained a strong cell infection. In addition, it has a strong immune escape, which is very worrying.

In an interview with Xinhua News Agency reporters, Professor Zhang Zuqiao, director of the Department of Popular Diseases, Los Angeles School of Public Health, the University of California, said that the BA.5 new subtype has high contagious, short lacked period, fast transmission speed, and high proportion of asymptomatic infections. Features, as the antibody level gradually decreases after a period of vaccination, the breakthrough infection rate of this virus will increase.
According to US media reports, when BA.5 strikes, many U.S. epidemic prevention and control measures have already been canceled, and flight travel has basically returned to the level before the epidemic. Most of the public have given up wearing masks and maintaining social distance. The virus can be taken.

Jeffrey Sax, the director of the Corporation of Columbia University, said in an interview with Xinhua News Agency that the epidemic was earlier and there are still many uncertainty. International cooperation of resistance should be strengthened to ensure that countries can take appropriate prevention and control measures, and obtain necessary diagnostic equipment, drugs, vaccines, etc.
