The coronavirus has claimed more than 500,000 lives worldwide, according to Johns Hopkins University.
More than a quarter of that total comes from the United States - which has the highest reported death toll.
The United States has yet to get a grip on the COVID-19 pandemic, with 36 states seeing a rise in week-to-week COVID-19 infections.
"They're probably looking at having to go back to a very strict lockdown to suppress the transmission," says Dr. Celine Gounder, a CNN medical analyst.
Connecticut and Rhode Island are the only two states reporting a drop in new weekly cases, according to Johns Hopkins University.
“If we don't use face coverings in settings where we can't social distance, if we don't practice appropriate social hygiene, we're going to see spread of disease,” says Sec. Alex Azar, of the Department of Health and Human Services.
Although President Donald Trump has avoided wearing masks in public, some Republicans are recommending that the public do so.
"We encourage everyone to wear a mask, uh, in the affected areas and where you can't maintain social distancing," says Vice President Mike Pence.
At least 13 states have paused or held back their reopening due to the rise in cases.
"We want to get the economy back, but you've got to do it in a measured way. And now we're seeing the consequences of community spread, which is even more difficult to contain than spread in a well-known physical location," says Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases
In New York, the numbers remain low. Gov. Andrew Cuomo says almost 62,000 tests were conducted Saturday and just under 1% came back positive. About 80 new cases were reported on Long Island.
