US Entering Fourth Wave of COVID-19, Epidemiologist Warns - Sputnik International

 A fourth wave of the coronavirus infection has started in the United States as new strains are becoming more prominent, epidemiologist Dr. Michael Osterholm, who served as a member of US President Joe Biden's COVID-19 transition advisory board, says.

"We seem to be in a cycle of regional activity and right now the upper midwest is lighting up with the northeast, and it won’t be long before the rest of the country will be following behind," Osterholm told Fox News on Sunday.

Asked whether the current spike in infections could be considered a "fourth wave," Osterholm said he believed so.

    "I believe that, in some ways, we're almost in a new pandemic," the epidemiologist said, adding that "The only good news is that the current vaccines are effective against this particular variant B.1.1.7. [British strain.]"
