The United States reported 210,479 new Covid-19 cases and 1,394 deaths on Sunday, according to Johns Hopkins University.
The latest figures bring the totals in the US to 20,636,663 infections and at least 351,580 fatalities.
The totals include cases from all 50 states, the District of Columbia and other US territories, as well as repatriated cases.
At least 13,071,925 vaccine doses have been distributed in the country and at least 4,225,756 shots administered, according to the US Centers for Disease Control and Prevention.
But around the US, hospitals are racing to keep up with surges of Covid-19 patients at numbers they have not seen at any other time in the pandemic.
On Sunday, the country reported 125,544 current Covid-19 hospitalizations, setting a new record, according to the Covid Tracking Project. The number has exceeded 100,000 for more than a month.
Health experts worry what will happen to those numbers if infections continue to spread.
"This is about total collapse of the health care system if we have another spike," said Dr. Brad Spellberg, chief medical officer at the Los Angeles County-University of Southern California Medical Center.
