The United States plans to end enhanced health screening of travelers from certain countries next week, and those visitors will no longer be funneled through 15 large U.S. airports.Those requirements were imposed in January to prevent the spread of COVID-19. The Centers for Disease Control and Prevention said the government will remove those edicts beginning Monday.The CDC said the current screening, which includes temperature checks and questioning travelers about COVID-19 symptoms, “has limited effectiveness” because some infected people have no symptoms or only minor ones. Travelers go through customs only after the health screening.The health agency said that of the 675,000 travelers who went through the process, fewer than 15 were found to have COVID-19 because of the extra screening.The health agency said that instead it will focus on other measures, including a stronger response to reports of illness at airports, collecting passenger-contact electronically to avoid long lines, and “potential testing to reduce the risk of travel-related transmission” of the virus.The extra health screening applies to people who have been in China, Iran, most countries in continental Europe, the United Kingdom, Ireland and Brazil. Most people coming from those countries who aren’t U.S. citizens have been barred entry to the country.The Homeland Security Department did not immediately respond to a request for comment Thursday.A trade group representing the nation’s largest carriers praised the change.“We continue to support spending scarce screening resources where they can best be utilized,” Airlines for America said in a statement Thursday, “and, given the extremely low number of passengers identified by the CDC as potentially having a health issue, agree that it no longer makes sense to continue screening at these airports.”Separately, 18 travel and airline groups asked the administration to start pre-flight virus testing as a way to reopen international travel. The groups argue that more screening could allow countries to lift travel restrictions and quarantines that have shut down most travel between the U.S. and Europe.Airlines including Delta and Southwest have lobbied the Transportation Security Administration to screen passengers for fever before allowing them on flights within the United States. However, the CDC questioned the usefulness of temperature screening because of the large number of infected people who do not have fevers, and no widespread screening of domestic passengers was launched.___This story has been updated to read that screening began at some airports in January, not February.___This story has been corrected to note that the COVID-19 health screening began at some airports in January, not February. 2771

The XFL will return in 2022, according to Dwayne “The Rock” Johnson, who now owns the league.Officials with the league had to shut down their inaugural 2020 season because of the coronavirus pandemic earlier this year and filed for bankruptcy in April. Johnson and his investor group bought the league in August for million, reportedly.“As owners, we’re proud to champion our XFL players, coaches, cities and fans into an electrifying 2022 season!” Johnson wrote on Twitter Thursday morning. “A league of culture, passion & purpose.” 549

The U.S. has now surpassed 17 million confirmed cases of COVID-19 and has yet again recorded more than 1 million cases of the virus in less than a week, according to a database kept by Johns Hopkins University.The U.S. reached the 16 million case threshold over the weekend. According to the COVID Tracking Project, the country is averaging more than 200,000 new cases of the virus every day, putting it on pace to record 1 million cases every five days.Since Oct. 30, the U.S. has recorded more than 8 million cases of COVID-19 — a number that represents 47% of all cases recorded since the virus reached the U.S. in January. The U.S. is currently in the midst of the most deadly stretch of the pandemic to date. The country surpassed 300,000 deaths linked to the virus on Monday. Since then, nearly 8,000 more people have died of the disease.The COVID Tracking Project reports that the U.S. has averaged more than 2,500 deaths every for the last week — and that number will likely increase in the weeks to come. The COVID Tracking Project also reports that record numbers of Americans are battling the virus in a hospital. The group says more than 113,000 people are currently hospitalized with the virus, leading many health care facilities — particularly those in rural areas — to reach maximum capacity levels.Spikes in COVID-19 typically trail behind spikes in cases and hospitalizations, meaning death totals will likely only increase in the weeks to come. 1481
