The United States just had its deadliest day on record due to the coronavirus as states across the country begin to ease restrictions meant to curb the spread of the virus, according to data published by the World Health Organization.

The U.S. saw 2,909 people die of Covid-19 in 24 hours, according to the data, which was collected as of 4 a.m. ET on Friday. That’s the highest daily Covid-19 death toll in the U.S. yet, based on a CNBC analysis of the WHO’s daily Covid-19 situation reports.

Before May 1, the next highest U.S. daily death toll was 2,471 reported on April 23, according to the WHO. State officials have previously warned that data on Covid-19 deaths are difficult to analyze because they often represent patients who became ill and were hospitalized weeks ago.
