The number of Americans newly diagnosed with the coronavirus is falling — a development experts say most likely reflects more mask-wearing but also insufficient testing — even as the disease continues to claim nearly 1,000 lives in the U.S. each day.About 43,000 new cases are being reported daily across the country, down 21% from early August, according to data compiled by Johns Hopkins University. While the U.S., India and Brazil still have the highest numbers of new cases in the world, the downward trend is encouraging.“It’s profoundly hopeful news,” said Dr. Monica Gandhi, an infectious-diseases expert at the University of California, San Francisco, who credits the American public’s growing understanding of how the virus spreads, more mask-wearing and, possibly, an increasing level of immunity.“Hopefully all those factors are coming into play to get this virus under control in this country that’s really been battered by the pandemic,” she said.But insufficient testing is probably concealing the full extent of the crisis, said Dr. Jonathan Quick, who leads the pandemic response for the Rockefeller Foundation, which has recommended the U.S. test 4 million people a day by fall.“We’re grossly under-testing in some of the places that are still having high caseloads,” Quick said, singling out Mississippi, Texas, Georgia and North Dakota as hot spots with high rates of positive test results.Even at 43,000 new cases per day, the U.S. remains far above the numbers seen during the spring, when new daily cases peaked at about 34,000, he said.“It’s a good trend, but nowhere near what we need to be,” Quick said of the recent decline.The virus is blamed for more than 5.7 million confirmed infections and about 178,000 deaths in the U.S. Worldwide, the death toll is put at more than 810,000, with about 23.7 million cases.Jeffrey Shaman, a public health expert at Columbia University, said he is skeptical enough people are immune to significantly slow the spread. But he agreed that changes in Americans’ behavior could well be making a difference, recalling the impact that people’s actions had in containing Ebola in West Africa several years ago.“Ebola stopped for reasons we didn’t anticipate at the time. It was so horrifying that people stopped touching each other,” Shaman said. Something similar may be happening with the coronavirus, he said.“I know I don’t have nearly the number of contacts that I used to,” Shaman said. “But if we relax that, if we get complacent, will we just see another outbreak?”The decline in newly reported cases in the U.S. comes even as deaths from the virus remain alarmingly high. Officials have reported an average of 965 deaths per day from COVID-19 recently, down from 1,051 deaths a day in early August.Deaths from the coronavirus are a lagging indicator — they trail new infections because of the time it takes for people to get sick and succumb to the disease.The percentage of tests coming back positive for the disease has also declined over the past two weeks, from 7.3% to 6.1%. But that comes as the total number of tests administered has fallen from its August peak of more than 820,000 a day, leveling off in recent weeks at about 690,000 a day.The situation has improved dramatically in several states that struggled with high caseloads earlier this summer.In Arizona, for example, officials reported 859 new cases Tuesday, down from a peak of 5,500 in late June. More than 2,000 people arrived at the state’s hospitals showing symptoms of the virus on a single day in early July. This week, that number has been less than 1,000.In Florida, where more than 10,000 people have died, the state reported 2,600 new virus cases Tuesday. Earlier in the summer, it was regularly reporting more than 10,000 new cases.Malinda Coler, 37, of San Francisco, said she has been diligent about mask wearing and other preventive measures, less to protect herself than a best friend who has a compromised immune system, with severe arthritis psoriasis.“So I wear a damned mask and get infuriated when others don’t,” she said.Most states now have some type of mask requirement, either through statewide orders issued by governors or from city and county rules that cover most of their population.Even some conservative governors have gone along with masks. Mississippi Gov. Tate Reeves mandated masks in all public places earlier this month, and Georgia Gov. Brian Kemp dropped a lawsuit against Atlanta in a dispute over a requirement by the state’s largest city.In Leeds, Alabama, Will Heath said he has seen greater adherence to mask rules around town, whether in stores or at his 5-year-old daughter’s cheerleading practice.He and his wife, a nurse, have worn masks all along but said the attitude among others has shifted from “Even if I get it, I’ll be OK,” to “Let’s make sure we don’t give it to somebody else.”“We have all been sort of operating under the assumption that we all have it or we’re going to get it eventually. So we want to make sure we don’t spread it,” Heath said.Many places around the U.S. are seeing pockets of contagion, especially in college towns where students are holding parties and crowding into bars.Over the past week, 531 students, faculty and staff at the University of Alabama in Tuscaloosa have tested positive for the virus, according to the school. Alabama said it tested nearly 30,000 students before classes began. The mayor of Tuscaloosa shut down bars for two weeks because of the spike, which could derail plans to continue the semester on campus.The university is still moving ahead with fall sports in the football-crazed state, with plans to allow only about 20,000 fans at its 101,000-capacity stadium and a ban on tailgating. Coach Nick Saban weighed in on the virus Monday, urging people to wear masks.“It’s not just about football. So, for people to make the right choices and decisions to wear their masks, do the things when they’re out publicly, respect the rules, respect the virus, that’s important,” he said.It’s not clear what will happen to case numbers as more school districts bring students back to classrooms and colleges reopen their campuses. In recent weeks, schools including the University of North Carolina, Michigan State and Notre Dame have moved instruction online after outbreaks on their campuses.Officials at the University of Tennessee at Knoxville said four students are facing disciplinary proceedings after three hosted off-campus parties with no mask or other distancing and another left isolation to meet with others despite testing positive for the virus.“If the facts reported to the university are accurate, these students will face at least suspension from the university, and potentially greater penalties,” Chancellor Donde Plowman wrote.___Associated Press writers Mae Anderson, Nicky Forster and John Zenor contributed to this story. 6888

The National Transportation Safety Board is finishing up its initial examination into the deadly Southwest Airlines engine failure Thursday -- but many questions remain unanswered.Investigators can't explain with certainty why the left engine of Southwest Airlines Flight 1380 malfunctioned when the plane was reaching over 32,000 feet. It's too soon to determine what happened, said National Transportation Safety Board Chairman Robert Sumwalt."I know people would want answers right away. We would do a very methodical investigation," Sumwalt told reporters Wednesday in Philadelphia. "Right now, we just want to document everything that we can." 656

The old king of mobile messaging is coming after the new king.BlackBerry filed a lawsuit in California on Tuesday against Facebook, along with its subsidiaries WhatsApp and Instagram, for infringing on its messaging patents.BlackBerry claims in the lawsuit that the social media companies developed messaging applications that "co-opt BlackBerry's innovations" by using patented features touching on security, the user interface, and battery life."We have a strong claim that Facebook has infringed on our intellectual property, and after several years of dialogue, we also have an obligation to our shareholders to pursue appropriate legal remedies," a spokesperson for BlackBerry said in a statement provided to CNN.Facebook brushed off the suit as little more than a desperate move from a fading company."Blackberry's suit sadly reflects the current state of its messaging business," Paul Grewal, Facebook's deputy general counsel, said in a statement. "Having abandoned its efforts to innovate, BlackBerry is now looking to tax the innovation of others. We intend to fight."Related: Is BlackBerry making a comeback?BlackBerry was an early leader in the messaging market with the success of its smartphones and BlackBerry Messenger product in the mid-2000s.The patents cited in the lawsuit describe foundational elements of today's messaging services. One patent deals with notifications for the total number of unread messages. Other patents address photo tagging and messaging time stamps.BlackBerry is seeking unspecified monetary damages. It also appears to be seeking a partnership."As a cybersecurity and embedded software leader, BlackBerry's view is that Facebook, Instagram, and WhatsApp could make great partners in our drive toward a securely connected future," the spokesperson said in the statement. "We continue to hold this door open to them."The-CNN-Wire? & ? 2018 Cable News Network, Inc., a Time Warner Company. All rights reserved. 1965

The Mormon church is parting ways with the Boy Scouts of America after more than a century.In a joint statement Tuesday night, the Church of Jesus Christ of Latter-day Saints and the Boy Scouts of America announced their decision to end their relationship next year after 105 years.The Boy Scouts serves about 330,000 Mormon youths, and the Mormon church is one of its largest sponsors."We have jointly determined that, effective on December 31, 2019, the church will conclude its relationship as a chartered organization with all Scouting programs around the world," the statement said.The Mormon church said it made the decision because it's expanded outside the United States, and wants to explore new youth programs that serve its international members.It will continue to work fully with the organization and support its goals and values until the end of next year. 878
