This Is Exactly When Coronavirus Cases Started Climbing Again

New data shows that COVID-19 cases have been rising in the U.S. since Memorial Day.

Desperate to engage in some outdoor fun over the Memorial Day weekend, countless Americans took advantage of easing quarantine restrictions by heading to beaches, barbecues, and other large gatherings—often while throwing caution to the wind when it came to nationwide social distancing guidelines. As a result, the annual holiday has been marked as the beginning of a consistent uptick in new U.S. cases that continues today, based on recent data from Johns Hopkins University.

According to CNBC's analysis of the telling data, based on a seven-day average, the number of new cases was reported at 20,600 a day on May 28—the lowest number in eight weeks. Ever since, however, numbers haves been on the rise. As of Wednesday June 3, the seven-day average was 21,763 new cases a day.

Researchers cite the fact that it can take up to 12 days for people to show symptoms of the coronavirus to explain why Memorial Day, which fell on May 25, was likely the beginning of the rise, even though the eight-week low was reported on May 28.

The trend engendered concern from Centers for Disease Control and Prevention (CDC) director, Robert Redfield, who recently told lawmakers he was worried that more Americans didn't seem to be following the agency's advice now that states have started reopening, CNBC reports.

States that began reopening earlier than others, such as Texas, Florida, and Arizona, have shown particularly large increases in new cases since Memorial Day. In fact, Florida reported 1,419 new cases on Jun. 4, the state's largest single-day increase since the pandemic began.

Though numbers aren't up everywhere, and former hot beds of the outbreak like New York have seen new cases start to decline, the CDC remains concerned about the country as whole—especially as reopening rolls on.

"We will continue to message as well we can," Redfield told the House Appropriations Committee during a hearing on the coronavirus, reported CNBC. "We're going to encourage people that have the ability to require to wear masks when they are in their environment to continue to do that."
