The U.S. reported more than 200,000 COVID-19 cases for the first time on Friday, an all-time high reached about three weeks after the nation first reported 100,000 daily cases on Nov. 4.

The nation recorded 205,557 new cases Friday. That rapid doubling, as reported by Johns Hopkins University, is reminiscent of the virus’ growth this spring, when exponential spread prompted widespread restrictions across the country in an effort to control the virus.

But experts warn that coronavirus testing numbers are likely to be erratic over the next week or so as fewer people get tested during the Thanksgiving holiday weekend and testing sites observe shorter hours.

The result could be potential dips in reported infections that offer the illusion that the spread of the virus is easing when, in fact, the numbers say little about where the nation stands in fighting COVID-19. The number of Americans who have tested positive passed 13 million Friday, according to Johns Hopkins University.

Here’s what to know Saturday:

• A panel of U.S. advisers will meet Tuesday to vote on how scarce, initial supplies of a COVID-19 vaccine will be given out once one has been approved.
• Kings County, New York, where Brooklyn is located, is the second American county to reach 7,500 reported deaths, after Los Angeles County in California. Globally, only 30 countries have reported 7,500 deaths, according to Johns Hopkins data.
• Many state leaders are again making moves to slow the spread. In Los Angeles County, a three-week stay-at-home order takes effect Monday. The most populous county on Friday hit an average of 4,500 cases a day over a five-day period, triggering the order.
• Several European countries were expected to relax coronavirus-related restrictions in the coming days. On Saturday, more than 150 people were arrested at an “anti-lockdown” protest in London, according to police.
• The NFL has ordered team facilities to be closed to in-person activities early next week in a bid to slow the spread of COVID-19 among players and staffers.
• Black Friday crowds were thinner this year as shoppers increasingly turned to online deals to avoid in-person shopping. That, however, didn’t stop some shoppers from camping out to score the new Sony PlayStation 5 and Microsoft Xbox Series X, two in-demand gaming consoles.
