Laboratories across the U.S. are buckling under a surge of coronavirus tests, creating long processing delays that experts say are undercutting the pandemic response.With the U.S. tally of confirmed infections at nearly 4 million Wednesday and new cases surging, the bottlenecks are creating problems for workers kept off the job while awaiting results, nursing homes struggling to keep the virus out and for the labs themselves as they deal with a crushing workload.Some labs are taking weeks to return COVID-19 results, exacerbating fears that people without symptoms could be spreading the virus if they don’t isolate while they wait.“There’s been this obsession with, ‘How many tests are we doing per day?’” said Dr. Tom Frieden, former director of the Centers for Disease Control and Prevention. “The question is how many tests are being done with results coming back within a day, where the individual tested is promptly isolated and their contacts are promptly warned.”Frieden and other public health experts have called on states to publicly report testing turnaround times, calling it an essential metric to measure progress against the virus.The testing lags in the U.S. come as the number of people confirmed to be infected worldwide passed a staggering 15 million, according to data compiled by Johns Hopkins University. The U.S. leads the world in cases as well as deaths, which have exceeded 142,000.New York, once by far the U.S. leader in infections, has been surpassed by California, though that is partly due to robust testing in a state with more than twice the population of New York.Guidelines issued by the CDC recommend that states lifting virus restrictions have a testing turnaround time of under four days. The agency recently issued new recommendations against retesting most COVID-19 patients to confirm they have recovered.“It’s clogging up the system,” Adm. Brett Giroir, assistant health secretary, told reporters last week.Zachrey Warner knows it all too well.The 30-year-old waiter from Columbus, Ohio, was sent home from work on July 5 with a high fever a few days after he began feeling ill. He went for a test five days later at the request of his employer.Almost two weeks and one missed pay period later, he finally got his answer Wednesday: negative.Though Warner said most symptoms — including fever, diarrhea, chest tightness and body aches — stopped a few days after he was tested, he wasn’t allowed to return to work without the result.It was “frustrating that I’ve missed so much work due to testing taking forever,” Warner said. “It is what it is ... (but) I’m glad I’m negative and happy to be able to get back to work this week.”Beyond the economic hurt the testing lags can cause, they pose major health risks, too.In Florida, which reported 9,785 new cases and a rise in the death toll to nearly 5,500, nursing homes have been under an order to test all employees every two weeks. But long delays for results have some questioning the point.Jay Solomon, CEO of Aviva in Sarasota, a senior community with a nursing home and assisted living facility, said results were taking up to 10 days to come back.“It’s almost like, what are we accomplishing in that time?” Solomon said. “If that person is not quarantined in that 7-10 days, are they spreading without realizing it?”Test results that come back after two or three days are nearly worthless, many health experts say, because by then the window for tracing the person’s contacts to prevent additional infections has essentially closed.“The turnaround times, particularly across the South are too long,” Dr. Deborah Birx of the White House coronavirus task force said on Fox.Birx said the U.S. had shorter turnaround times in April, May and early June, but that “this surge and this degree of cases is so widespread compared to previously,” she said.Dr. Leana Wen, a public health professor at George Washington University said it’s reasonable to tell people awaiting test results to isolate for 24 hours, but the delays have been unacceptable.“Imagine you tell a parent with young children to self-isolate for 10 days or more without knowing they actually have COVID? I mean, that’s ridiculous. That’s actually absurd,” Wen said.U.S. officials have recently called for ramping up screening to include seemingly healthy Americans who may be unknowingly spreading the disease in their communities. But Quest Diagnostics, one of the nation’s largest testing chains, said it can’t keep up with demand and most patients will face waits of a week or longer for results.Quest has urged health care providers to cut down on tests from low-priority individuals, such as those without symptoms or any contact with someone who has tested positive.As testing has expanded, so have mask orders and other measures aimed at keeping infections down. Ohio, Indiana, Minnesota and Oregon became the latest to announce statewide mandatory mask orders Wednesday.The U.S. is testing over 700,000 people per day, up from less than 100,000 in March. Trump administration officials point out that roughly half of U.S. tests are performed on rapid systems that give results in about 15 minutes or in hospitals, which typically process tests in about 24 hours. But last month, that still left some 9 million tests going through laboratories, which have been plagued by limited chemicals, machines and kits to develop COVID-19 tests.There is no scientific consensus on the rate of testing needed to control the virus in the U.S., but experts have recommended for months that the U.S. test at least 1 million to 3 million people daily.Health experts assembled by the Rockefeller Foundation said last week that the U.S. should scale up to testing 30 million Americans per week by the fall, when school reopenings and flu season are expected to further exacerbate the virus’s spread. The group acknowledged that will not be possible with the lab-based testing system.The National Institutes of Health has set up a “shark tank” competition to quickly identify promising rapid tests and has received more than 600 applications. The goal is to have new testing options in mass production by the fall.Until then, the backbone of U.S. testing remains at several hundred labs with high-capacity machines capable of processing thousands of samples per day. Many say they could be processing far more tests if not for global shortages of testing chemicals and other materials.Dr. Bobbi Pritt of the Mayo Clinic in Rochester, Minnesota, says the hospital’s machines are running at just 20% capacity. Lab technicians run seven different COVID-19 testing formats, switching back and forth depending on the availability of supplies.At Emory University Hospital in Atlanta, lab workers lobby testing manufacturers on a weekly basis to provide more kits, chemicals and other materials.“There’s no planning ahead, we just do as many as we can and cross our fingers that we’ll get more,” said Dr. Colleen Kraft, who heads the hospital’s testing lab.___This story has been corrected to show that the CDC has issued guidelines recommending against repeat testing for patients recovering from coronavirus.___Webber reported from Fenton, Michigan, and Sedensky reported from Philadelphia.

Lawyers for Breonna Taylor allege in court records that she was targeted in a police operation to gentrify a neighborhood in western Louisville. Taylor was shot and killed back in March by Louisville Metro Police officers when police conducted a “no-knock raid” on her home. Thinking the police officers were intruders, Taylor’s boyfriend, Kenneth Walker, allegedly shot at police.Officers returned fire, striking, and killing Taylor.According to the lawsuit, which was filed Sunday in Jefferson Circuit Court on behalf of Taylor's family, lawyers said there were plans underway for a "high dollar, legacy-creating real estate development" for Elliot Avenue. Taylor's ex-boyfriend Jamarcus Cordell Glover was renting a home on the street and it created a "roadblock" for the project, court documents stated."The police unit's efforts to clean house on Elliott became so outrageous, unlawful, corrupt, and reckless that a bogus, no-knock search warrant was obtained for the home of Breonna Taylor, a woman with no criminal history, no drugs in her home, no targets in her home, and whose home was more than 10 miles from Elliott Avenue," lawyers stated in the court documents.Lawyer's Ben Crump and his co-counselors Sam Aguiar and Lonita Baker issued a statement about the refiling.“Connecting the dots, it’s clear that these officers should never have been at Breonna Taylor’s home in the first place, and that they invaded the residence with no probable cause," they said in a joint press release. "The officers who robbed Breonna of her life -- and Tamika Palmer of her daughter -- exhibited outrageous, reckless, willful, wanton, and unlawful conduct. As a consequence, the city lost one of its most precious essential frontline workers, who risked her life daily to save her fellow residents in a pandemic. This is a grievous offense against Breonna, her family, and the greater Louisville community."You can read the full lawsuit below: 1950

LAKE BUENA VISTA, Fla. (AP) — Players and coaches from the New Orleans Pelicans and Utah Jazz knelt alongside one another before the first game of the NBA restart. It was an unprecedented image for the league in unprecedented times. The coaches — New Orleans’ Alvin Gentry and Utah’s Quin Snyder — were next to one another Thursday, their arms locked together. Some players raised a fist as the final notes of “The Star-Spangled Banner” were played, the first of what is expected to be many silent statements calling for racial justice and equality following the deaths of Breonna Taylor and George Floyd in recent months.The league has a long-standing rule that requires players to stand during the national anthem. But commissioner Adam Silver backed the players' decision. “I respect our teams’ unified act of peaceful protest for social justice and under these unique circumstances will not enforce our long-standing rule requiring standing during the playing of our national anthem," Silver said in a statement. 1025

Laurent Duvernay-Tardif, a guard for the defending Super Bowl Champs Kansas City Chiefs, announced his decision Friday night to opt out of the 2020 NFL season. Duvernay-Tardif is the first NFL player to opt out of the 2020 season after the NFLPA and league came to a joint agreement Friday allowing players to sit out the season over coronavirus concerns.Duvernay-Tardif played 14 games last season for the Chiefs.In April, Duvernay-Tardif was featured by Sports Illustrated as he put his medical degree to use on the front lines fight the coronavirus. Duvernay-Tardif penned an op-ed in Sports Illustrated about his experience working as a doctor on the front lines during the pandemic.“When you’re going in to help it’s more about your duty as a doctor and a citizen,” he wrote in April. “It’s not the time to be the hero and be impulsive. You’ve gotta do it the right way. You’ve gotta really take this seriously when it comes to washing your hands, not touching anything.”On Friday, Duvernay-Tardif said he is confident the Chiefs have a good plan for returning to play, but the risks remain too high.“Being at the frontline during this offseason has given me a different perspective on this pandemic and the stress it puts on individuals and our healthcare system,” he wrote. “I cannot allow myself to potentially transmit the virus in our communities simply to play the sport that I love. If I am to take risks, I will do it caring for patients.” 1460

LAS VEGAS — Internet juggernaut Amazon is flourishing during the COVID-19 pandemic as people turn to online shopping for supplies. But, Nevada authorities are investigating the company after insiders say employees are getting sick and management is slow with revealing details.In a massive, 2.4 million square foot facility near Sloan and Tropical Parkway in Las Vegas, hundreds of Amazon employees file in and help the behemoth internet company deliver everything from above ground swimming pools to toothbrushes.In a public relations videoes, Amazon has touted the steps the company is taking to combat the spread of COVID-19. The precautions include employee temperature checks, mandatory mask-wearing, routine building cleaning, and social distancing for employees.But several Amazon employees are speaking out about their safety."Some people aren't even following [those precautions], and furthermore, in the break room, there's a lot of people, and it's hard for us not to come into contact with each other because we are right next to each other," said one insider who spoke on a condition of anonymity.The same insider fears retaliation for revealing details.She believes the company, which brought in about 0 billion in 2019, has been slow to reveal new cases of COVID-19 among Amazon employees."We were concerned already because we are in a warehouse, and there are so many people and we don't know where [the new cases] are coming from or who has [COVID-19]," she said.The trouble started in March when word began to spread among employees of possible illness. At the time, the company allowed for unlimited, unpaid time off for employees.The insider says management otherwise downplayed the presence of the illness among employees."Pretty much don't worry about it, and they told us it wasn't in our warehouse, it was in another, and it's all just a rumor," she said.But as weeks went by, the company acknowledged cases among employees.An Amazon spokesperson confirmed a case at a "North Las Vegas facility" on April 24.The company operates several large warehouses scattered around Southern Nevada, and insiders say concerns spread even more among employees about the exact location of the confirmed case.In fact, an internal email revealed that the company's public relations team deemed local news reports about the situation as "inaccurate," adding the positive case was at a facility internally dubbed "LAS 2" and at the time, no reported cases at the facility named "LAS 7."The email instructed employees to disregard news stories, and management would "hopefully report new cases before it hits the news.""When we had the second confirmed case, there was one person in management — I'm not sure of his position — but they had made a comment that, 'Well, by now you all should be immune to it. If you've been exposed to it, so you have nothing to worry about," the Amazon insider said.The situation went downhill, according to the Amazon insider.In an internal communication sent on May 5, Amazon revealed that an employee at the "LAS 7" facility had tested positive for COVID-19 on April 30. The email said that the employee was present at the facility for several weeks prior to testing positive.The company told employees the facility had been "deep cleaned" in accordance with the U.S. Centers for Disease Control and Prevention guidelines."It's hard to say you are sanitizing the place, which is not sanitized, by using it every day, the whole time we're there," the Amazon insider said. "Close it down for two days since you hired so many people or allow those who are sick not to feel threatened with their jobs if they need to take off."The insider says the company eliminated the unlimited time off for employees despite a rise in the number of reported cases among Amazon employees.Internal communications later revealed new reported cases at the LAS 7 facility on:May 11May 13May 15May 18May 22June 1June 5June 10June 15June 24July 15 (multiple individuals)July 18 (multiple individuals)July 21 (multiple individuals)The email to employees indicated the company was unable to reveal who had tested positive, citing privacy concerns."We work very hard for these people," the Amazon insider said. "We go above and beyond, and some people I see, they work many, many, many hours just to help those in our community."In response to a request for comment, Amazon's public relations representatives released generic statements that did not include specific locations or confirmed cases."We are supporting the individuals who are recovering. Our top concern is ensuring the health and safety of our employees, and we invested approximately billion from April to June on COVID-related initiatives to get products to customers and keep employees safe," Lisa Guinn, an Amazon spokesperson, said. "This includes spending more than 0 million in the first half of the year on COVID-19 safety measures, with investments in personal protective equipment, enhanced cleaning of our facilities, less efficient process paths that better allow for effective social distancing, higher wages for hourly teams, and developing our own COVID-19 testing capabilities."Authorities with the Nevada Occupational Safety and Health Administration have revealed that there are multiple, active investigations into local Amazon warehouses. There are two active investigations at the "LAS 7" warehouse, nine active investigations at the "LAS 2" warehouse, and additional complaints at other facilities in the Las Vegas valley.State authorities could not reveal details about the cases citing the ongoing nature of the investigations.This story was originally published by Joe Bartels on KTNV in Las Vegas. 5717
