The number of deaths per day from the coronavirus in the U.S. has fallen in recent weeks to the lowest level since late March, even as states increasingly reopen for business.

Deaths from COVID-19 across the country are down to about 680 a day, compared with around 960 two weeks ago, according to an Associated Press analysis of data compiled by Johns Hopkins University.

Stay-at-home orders imposed in March, combined with the use of face masks and other social-distancing measures, have been bringing down the daily death toll since mid-April, and the U.S. as a whole is still seeing the positive effects, even though people are starting to work, shop and eat out again.

It looks that way in Washington state’s King County, where the first nursing home outbreak in the U.S. killed 45 people at the Life Care Center in suburban Seattle.

While it is unclear how much specific treatments may have contributed to the decline in deaths, doctors are trying antivirals such as remdesivir, plasma donated from people who have recovered from the virus and steroids such as dexamethasone, which grabbed attention this week with reports confirming it can save the lives of many of the sickest patients.
