The tracker had showed 827 just a few hours earlier. The United States has the third highest number of confirmed cases behind China and Italy, and the US death rate is now 1.5 percent, based on reported cases.
The true number of infected people is believed to be far higher, meaning the real death rate would be lower.
New York is one of the hardest hit states in the country, with 280 deaths in New York city since the start of the pandemic, according to the tracker.
The virus has killed more than 21,000 people around the world after it was first identified in Hubei province in late December.
A projection shared with Congress earlier this month said that between 70 to 150 million people could eventually be infected in the United States.
If the real mortality rate is one percent, this would result in 700,000 to 1.5 million deaths. (AFP)
