The U.S. death toll from the coronavirus topped 500,000 on Sunday, according to an NBC News tally — a milestone that underscores the grave threat the virus still poses even as more people are vaccinated.

The coronavirus has killed more than 2,462,000 people worldwide, according to data compiled by Johns Hopkins University. More than a fifth of all deaths worldwide have occurred in the the U.S., which has less than 5 percent of the global population.

NBC News’ tally showed that about 500,700 people had died of Covid-19 as of midnight Sunday ETThe number rivals the populations of Atlanta and Sacramento, California.

More than 28,206,600 cases have been confirmed in the U.S., according to the NBC News tally. The average number of daily new cases has declined in recent days, however. The number fell below 100,000 on Feb. 12 for the first time in months.

Public health experts and top government officials have said precautions must remain in place to slow the spread of the virus.

“We are still at about 100,000 cases a day. We are still at around 1,500 to 3,500 deaths per day. The cases are more 2½-fold times what we saw over the summer,” Dr. Rochelle Walensky, the director of the Centers for Disease Control and Prevention, said Sunday on NBC News’ “Meet the Press.”
