Potential accuracy issues with a widely used coronavirus test could lead to false results for patients, U.S. health officials warned.The Food and Drug Administration issued the alert Monday to doctors and laboratory technicians using Thermo Fisher’s TaqPath genetic test. Regulators said issues related to laboratory equipment and software used to run the test could lead to inaccuracies. The agency advised technicians to follow updated instructions and software developed by the company to ensure accurate results.The warning comes nearly a month after Connecticut public health officials first reported that at least 90 people had received false positive results for the coronavirus. Most of those receiving the false results were residents of nursing homes or assisted living facilities.A spokeswoman for Thermo Fisher said the company was working with FDA “to make sure that laboratory personnel understand the need for strict adherence to the instructions for use.” She added that company data shows most users “follow our workflow properly and obtain accurate results.”The FDA said one possible problem was related to the incorrect use of equipment that rapidly spins samples in preparation for processing. The agency’s letter tells lab workers to follow new instructions developed by the company for this step.A second issue relates to the software used on Thermo Fisher’s testing platform. FDA said labs must upgrade the software to a new version.Dr. Albert Ko of Yale’s School of Public Health said the potential accuracy problems have “pretty serious implications” given that Thermo Fisher’s test is used widely both in the U.S. and around the world to screen for coronavirus.The FDA statement did not provide any details on how many test results may have been affected by the problem.Lab tests are the backbone of U.S. screening for coronavirus, accounting for more than half of the roughly 750,000 tests developed daily. The tests look for traces of coronavirus’ genetic material in nasal swabs taken from patients.Thermo Fisher’s test was granted emergency use by the FDA in mid-March. The test runs on a large, automated machine used in hospital, government and commercial labs to look for diseases such as HIV, hepatitis and flu.The FDA has used its emergency powers to OK more than 200 tests for coronavirus since February. No test is perfect and all are expected to give at least a small percentage of false negatives and false positives.___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

President Donald Trump and Democratic challenger Joe Biden sparred Thursday in their final presidential debate, hoping to sway undecided voters in the Nov. 3 election.A look at how their statements from Nashville, Tennessee, stack up with the facts:TRUMP: “All he does is talk about shutdowns. But forget about him. His Democrat governors Cuomo in New York, you look at what’s going on in California, you look at Pennsylvania, North Carolina. Democrats — Democrats all. They’re shut down so tight, and they’re dying.”BIDEN: “Look at the states that are having such a spike in the coronavirus. They’re the red states. They’re the states in the Midwest or the states in the Upper Midwest. That’s where the spike is occurring significantly.”THE FACTS: Neither of them is right. Coronavirus isn’t a red-state problem or a blue-state problem. It’s a public health problem that affects human beings, no matter where they live or what their politics are.Some Republican-led states that were quick to reopen saw a surge of virus cases in the summer and are still struggling to get their transmission rates down. Florida’s test positivity rate is about 12% currently, a level indicating widespread transmission. South Dakota is approaching 35%.Democratic-led states like New York that were hit hard in the initial wave closed down and got their virus transmission rates down to very low levels. But they’re now seeing rebounds in certain local communities, prompting them to target renewed restrictions.Nevada and Pennsylvania are two states with Democratic governors and high transmission rates at currently 20% and 10% respectively, based on a 14-day trend.___TRUMP: Wind turbines’ fumes “kill all the birds” and give off more “fumes” than natural gas.FACTS: Not so. The U.S. Department of Energy says “wind turbines do not release emissions that can pollute the air or water (with rare exceptions), and they do not require water for cooling.”The U.S. Fish and Wildlife Service says, “The most comprehensive and statistically sound estimates show that bird deaths from turbine collisions are between 140,000 and 500,000 birds per year.” It also says that 599 million birds are killed a year colliding with buildings, 6.6 million birds die a year running into communication towers and 214 million birds die a year from running into cars and other vehicles.___TRUMP: The Paris accord meant “we were going to have to spend trillions of dollars.... They did a great disservice. They were going to take away our business.”THE FACTS: The Paris accord, an international agreement that aims to halt the rise in global temperatures, is based on voluntary emission reductions. No nation was forced to do anything.___TRUMP, speaking about children who were separated from parents at the U.S.-Mexico border: “They are so well taken care of, they’re in facilities that are so clean.”THE FACTS: That is false.At the height of the separations in 2018, Border Patrol facilities were cramped well beyond capacity with migrants who were kept in squalid conditions, according to watchdog reports and the lawyers responsible for a federal settlement that governs how children are cared for in immigration custody. Long-term facilities for adults and children were at capacity, meaning the administration held people in the small border stations for much longer than the 72 hours normally allowed by law.The stations are hardly meant for long-term care. Children were not provided hot meals, families slept on the floor on top of Mylar blankets. Flu and sickness ran rampant, and hundreds of small children were kept together without adequate care.___TRUMP, on immigrants who are released from custody in the U.S. to wait out their cases being allowed to stay: “They say they come back, less than 1% of the people come back. We have to send ... Border Patrol out to find them.”THE FACTS: That’s false. There are far fewer no-shows for immigration hearings among those who are release pending their cases. According to Justice Department Statistics, a majority come back for their hearings.___BIDEN: “He says about the Poor Boys, last time we were on a stage here, said -- I told them to stand down and stand ready. Come on. This guy has a dog whistle as big as a fog horn.”THE FACTS: That is not exactly what Trump said and that is not the name of the neo-fascist group.During the last debate, on Sept. 29, Trump was asked if he would condemn white supremacist and militia groups that have shown up at some protests in the U.S. He said, “Give me a name” and Biden chimed in by saying, “Proud Boys,” a reference to the far-right extremist group that has shown up at protests in the Pacific Northwest.“Proud Boys, stand back and stand by,” Trump said. He did not tell them to “stand ready,” though it’s debatable whether there is a material difference.___BIDEN: “Not one single person with private insurance would lose their insurance under my plan, nor did they under ‘Obamacare,’ they did not lose their insurance, unless they chose they wanted to go to something else.”THE FACTS: He's wrong about “Obamacare.”Then-President Barack Obama promised if you liked your health insurance, you could keep it under his Affordable Care Act, but that’s not what happened for some.When “Obamacare” took effect in 2014, several million people lost individual health insurance plans that no longer met minimum standards established by the law. A backlash forced the White House to offer a work-around, but the political damage was done.Health insurance is such a complicated area that almost any action has the potential for unintended consequences.___TRUMP on his taxes: “They keep talking about 0, which I think is a filing fee. ... Tens of millions of dollars (in income taxes) I prepaid.” On his China bank account: “I was a businessman in 2013 and I closed the account in 2015.”THE FACTS: Trump is not being honest about his taxes.Reporting by The New York Times, which obtained his tax records, contradicts his claims.The IRS does not charge taxpayers a filing fee, though tax preparation services do. The 0 that Trump paid in 2016 and 2017 in the income taxes was to the federal government, not a tax preparation service.It’s not clear what Trump is talking about with regard to prepaying his taxes, but what matters is what he ultimately owed the government. Americans often have their income tax payments deducted from their paychecks. The Times reported that Trump, starting in 2010, claimed and received an income tax refund that totaled .9 million, which was at the core of an ongoing audit by the IRS. The Times said a ruling against Trump could cost him 0 million or more.Nor did Trump close his Chinese bank account, according to Alan Garten, a lawyer for Trump’s company. He told the Times that the account remains open, though the company’s office in China has been inactive since 2015.___TRUMP: “Joe got .5 (million) from Russia. And it came through Putin because he was very friendly with the former mayor of Moscow, and it was the the mayor of Moscow’s wife. And you got .5. Your family got .5 million. Someday you’re going to have to explain why.”THE FACTS: There is no evidence of this. Trump is falsely characterizing a recent report by Republican Sen. Ron Johnson, who investigated Biden’s son, Hunter, and his business dealings in Ukraine.The report did not allege that Joe Biden himself got .5 million or that Russia President Vladimir Putin had anything to do with such a payment. Nor does the report allege that Hunter Biden pocketed the money himself. The report said the sum went instead to an investment firm he co-founded. Hunter Biden’s lawyer has said in a statement to reporters that his client had no interest in and was not a founder of the firm.___TRUMP on the toll of COVID-19 in the U.S.: “So as you know 2.2 million people, modeled out, were expected to die.”THE FACTS: This was his first line in the debate, and it is false. The U.S. death toll from the pandemic was not expected to be that high.Such an extreme projection was merely a baseline if nothing at all were done to fight the pandemic. Doing nothing was never an option and public-health authorities did not expect over 2 million deaths.Trump often cites the number to put the reality of more than 220,000 deaths in a better light and to attempt to take credit for reducing projected mortality.At an April 1 briefing, when Trump and his officials discussed an actual projection of 100,000 to 240,000 deaths, the president held out hope of keeping deaths under 100,000. “I think we’re doing better than that.” He has repeatedly moved the goal posts to make the massive mortality and infection numbers look better.___TRUMP: “We’re rounding the turn. We’re rounding the corner. It’s going away.”THE FACTS: No, the coronavirus isn’t going away. It’s coming back. New cases are on the rise toward their summer peak. Deaths have also been increasing.According to data through Oct. 21 from Johns Hopkins University, the 7-day rolling average for daily new cases in the U.S. rose over the past two weeks from over 42,300 on Oct. 7 to nearly 60,000 on Oct. 21.According to data through Oct. 21 from Johns Hopkins University, the 7-day rolling average for daily new deaths in the U.S. rose over the past two weeks from 695 on Oct. 7 to 757 on Oct. 21. 9330

President Donald Trump falsely claimed Saturday that the New York Stock Exchange re-opened the day after the September 11, 2001, terrorist attacks in an effort to justify holding a rally on the same day that a mass shooting occurred at a synagogue in Pittsburgh.Speaking at a planned campaign rally in Illinois, Trump said he had weighed whether to cancel his rally as well as a speech at an agricultural convention earlier in the day in Indianapolis, Indiana, but ultimately decided against it, saying such a move would amount to giving the killer an edge. He compared his decision to continue with the rally to reopening the NYSE after the September 11 attacks, something that did not happen."And with what happened early today -- that horrible, horrible attack in Pittsburgh -- I was saying maybe I should cancel both this and that," Trump said, referring to the rally and his earlier appearance at the agricultural convention. "And then I said to myself, I remember Dick Grasso, a friend of mine, great guy. He headed up the New York Stock Exchange on September 11. And the New York Stock Exchange was open the following day. He said -- and what they had to do to open it you wouldn't believe. We won't even talk to you about it. But he got that exchange open." 1273

Politifact combed through hundreds of lies in 2018 and revealed its "Lie of the Year." This year, the political fact-checking website, picked the online smear campaign against the Parkland students after the deadly school shooting in Florida.Gina Montalto, 14, was one of the students killed during the shooting at Marjory Stoneman Douglas High School in Parkland, Florida. For her family, this will be the first Christmas without her.“It is by far the toughest,” says her father, Tony Montalto. “Gina loved the holiday season. She loved decorating for Christmas.”Seventeen families lost loved ones in the shooting. But not even a tragedy involving children stopped online trolls from starting conspiracy theories that falsely accused students of being “crisis actors.” Others claimed the teens had secretly organized before the shooting.“We are not actors,” says Montalto. “We are not politically driven. We’re parents and spouses that lost our loved ones.”The amount of lies leveled at the Parkland students and their families were enough for Politifact to name the smears as its lie of the year.“We felt the smears against the Parkland students were so egregious against young people who had done nothing to bring this on that it did bring it to another level,” said Angie Holan, a Politifact editor.Holan said the smear campaign is a troubling sign of where the country is in these polarizing times.“If people want to come forward and debate political issues because of something that happened to them in their everyday lives and then they would get smeared – it just seems like something new and disturbing,” said Holan.After the shooting at Marjory Stoneman Douglas High School, Montalto became the president of Stand with Parkland, a national organization that pushes for laws that address violence in schools. He said it makes him angry and sad that some people think the shooting was fabricated.“It’s very hard to think that people would believe that this could be a hoax,” he says. “As we experience the tremendous loss, we know the reality of the situation. Every day we walk past an empty bedroom.”In determining the lie of the year, Holan said she and her team look for the most significant falsehoods and that are politically significant.In Politifact’s online poll, readers chose a different lie of the year from President Donald Trump.At a campaign rally back in October, President Trump said, "The Democrats want to invite caravan after caravan of illegal aliens into our country. And they want to sign them up for free health care, free welfare, free education, and for the right to vote." Politifact rated the claim false and called the comments inaccurate and a distortion of the facts. 2739
