According to statistics from Johns Hopkins University in the United States, as of 19:30 EST on February 21 (8:30 Beijing time on February 22nd), there were 28129860 confirmed cases of COVID-19 in the United States and 49880 deaths, the highest in the world.
In addition, variants of COVID-19 found in the United Kingdom and South Africa appear in many parts of the United States.
According to the data of the U.S. Centers for Disease Control and Prevention, as of February 18 local time, a total of 1,549 cases of mutant novel coronavirus have been confirmed in 43 states in the United States.
Experts say that the new variant strain is more infectious, which may lead to a faster rise in new cases in the United States and more deaths, causing another crisis.
Dr. Anthony Fauci, an infectious disease expert and one of the leading public health advisers in the United States, said on the 21st that Americans are likely to still need to wear masks to prevent COVID-19 by 2022.
He also noted that many Americans are currently tired of measures to prevent the virus and pay enough attention to the stronger infectiousness of the new variant strains of the virus, which is likely to lead to a counterattack of the pandemic.
