The total US death toll from the coronavirus pandemic topped 4 000 early Wednesday, more than double the number from three days earlier, according to a tally by Johns Hopkins University.
The number of deaths was 4 076 - more than twice the 2 010 recorded late Saturday.
More than 40% of recorded deaths nationally were in New York state, the Johns Hopkins data showed.
On Tuesday the United States exceeded the number of deaths in China, where the pandemic emerged in December before spreading worldwide.
The number of confirmed US cases has reached 189 510, the most in the world, though Italy and Spain have recorded more fatalities.
After initially downplaying the threat from new coronavirus in the early stages of the US outbreak, President Donald Trump warned of "a very, very painful two weeks" to come for the country on Tuesday.
