February 23rd local time, some U.S. experts said that although the number of new confirmed cases in the United States has decreased in a single day in recent days, the more easily spread of COVID-19 variants may cause a new round of growth in the United States cases in the spring.
According to the data updated by the Centers for Disease Control and Prevention on the 23rd local time, the United States has reported at least 1,932 cases of COVID-19 variant infections in the United Kingdom, South Africa and Brazil.
Among them, 1881 cases of COVID-19 variant strain infection were found in the United Kingdom, and 46 cases of variant strain infection were found in South Africa and 5 in Brazil, respectively.
The U.S. Centers for Disease Control and Prevention said that these data were only obtained from the analysis of positive samples and did not represent the actual spread of mutant strains in the United States.
Previously, U.S. experts have said that due to the low number of genetic sequencing in the United States, the actual number of infected people may be much higher than the figures released by the U.S. Centers for Disease Control and Prevention.
According to CNN, some American experts predicted on the 23rd that the coronavirus variant found in the United Kingdom is likely to drive a new round of growth in U.S. cases in the spring.
The report quoted Trevor Bedford, a biology and genetics expert at Fred Hutchinson Cancer Research Center in the United States, as saying that the mutant strain may cause a new wave in April or May. And measures such as vaccination, wearing masks and social distancing will help stop the further spread of the virus.
Josh Schiffel, another infectious disease expert at Fred Hutchinson Cancer Research Center, also said it is difficult to stop another round of case growth given the impact of the COVID-19 variant strain.
