After struggling to ramp up coronavirus testing, the U.S. can now screen several million people daily, thanks to a growing supply of rapid tests. But the boom comes with a new challenge: keeping track of the results.All U.S. testing sites are legally required to report their results, positive and negative, to public health agencies. But state health officials say many rapid tests are going unreported, which means some new COVID-19 infections may not be counted.And the situation could get worse, experts say. The federal government is shipping more than 100 million of the newest rapid tests to states for use in public schools, assisted living centers and other new testing sites.“Schools certainly don’t have the capacity to report these tests,” said Dr. Jeffrey Engel of the Council of State and Territorial Epidemiologists. “If it’s done at all it’s likely going to be paper-based, very slow and incomplete.”Early in the outbreak, nearly all U.S. testing relied on genetic tests that could only be developed at high-tech laboratories. Even under the best circumstances, people had to wait about two to three days to get results. Experts pushed for more “point-of-care” rapid testing that could be done in doctors offices, clinics and other sites to quickly find people who are infected, get them into quarantine and stop the spread.Beginning in the summer, cheaper, 15-minute tests — which detect viral proteins called antigens on a nasal swab — became available. The first versions still needed to be processed using portable readers. The millions of new tests from Abbott Laboratories now going out to states are even easier to use: they’re about the size of a credit card and can be developed with a few drops of chemical solution.Federal health officials say about half of the nation’s daily testing capacity now consists of rapid tests.Large hospitals and laboratories electronically feed their results to state health departments, but there is no standardized way to report the rapid tests that are often done elsewhere. And state officials have often been unable to track where these tests are being shipped and whether results are being reported.In Minnesota, officials created a special team to try and get more testing data from nursing homes, schools and other newer testing sites, only to be deluged by faxes and paper files.“It’s definitely a challenge because now we have to do many more things manually than we were with electronic reporting,” said Kristen Ehresmann, of the Minnesota Department of Health.Even before Abbott’s newest BinaxNOW rapid tests hit the market last month, undercounting was a concern.Competitors Quidel and Becton Dickinson have together shipped well over 35 million of their own quick tests since June. But that massive influx of tests hasn’t showed up in national testing numbers, which have mostly ranged between 750,000 and 950,000 daily tests for months.Besides tallying new cases, COVID-19 testing numbers are used to calculate a key metric on the outbreak: the percentage of tests positive for COVID-19. The World Health Organization recommends countries test enough people to drive their percent of positives below 5%. And the U.S. has mostly been hovering around or below that rate since mid-September, a point that President Donald Trump and his top aides have touted to argue that the nation has turned the corner on the outbreak. The figure is down from a peak of 22% in April.But some disease-tracking specialists are skeptical. Engel said his group’s members think they aren’t getting all the results.“So it may be a false conclusion,” he said.One of the challenges to an accurate count: States have wildly different approaches. Some states lump all types of tests together in one report, some don’t tabulate the quick antigen tests at all and others don’t publicize their system. Because antigen tests are more prone to false negatives and sometimes require retesting, most health experts say they should be recorded and analyzed separately. But currently the vast majority of states do not do that and post the results online.The federal government is allocating the tests to states based on their population, rather than helping them develop a strategy based on the size and severity of their outbreaks.“That’s just lazy” said Dr. Michael Mina of Harvard University. “Most states won’t have the expertise to figure out how to use these most appropriately.”Instead, Mina said the federal government should direct the limited test supplies to key hot spots around the country, driving down infections in the hardest-hit communities. Keeping tighter control would also ensure test results are quickly reported.Johns Hopkins University researcher Gigi Gronvall agrees health officials need to carefully consider where and when to deploy the tests. Eventually, methods for tracking the tests will catch up, she said.“I think having the tools to determine if someone is infectious is a higher priority,” she said.___AP data journalist Nicky Forster contributed to this story___Follow Matthew Perrone on Twitter: @AP_FDAwriter___The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

After earthquakes and molten lava tore open the earth in Hawaii, residents of the Big Island have new threats to worry about: acid rain and volcanic smog.The Kilauea eruption last week left cracks on the ground, releasing slow-moving lava and toxic gas into island communities.In addition to the lava and volcanic ash spewing out of the ground, officials have warned of dangerous levels of sulfur dioxide gas. 417

A woman who was caught on camera calling 911 dispatchers on a Black bird watcher in New York City’s Central Park will face charges.The Manhattan District Attorney announced Monday his office has initiated a prosecution of Amy Cooper for falsely reporting an incident.Cooper was walking her dog in the park in May and was seen on camera having a confrontation with a Black man, who was birdwatching at the time. The man, Christian Cooper (no relation to Amy Cooper) told Amy Cooper that by not putting her dog on a leash in that section of the park, she was in violation of park rules.In the cell phone video taken by Christian Cooper, Amy Cooper is heard talking to 911 dispatchers and telling them a Black man was threatening her life. Cooper was issued a Desk Appearance Ticket for an arraignment in October.In a statement posted online, the DA is asking others who have been “the target of false reporting to contact our Office. We are strongly committed to holding perpetrators of this conduct accountable.” 1019

After losing her mother to COVID-19, a comedian has launched a mask-wearing crusade.Through a pixilated image on her iPad, Laurie Kilmartin strained her eyes desperately hoping to see her mother’s chest rise on the other end of their Facetime call, but after five minutes of silence, Laurie knew the coronavirus had won.Joanne Kilmartin died alone inside a California nursing home.After an hour of crying into her screen, Laurie and her sister told doctors it would be okay to end the call. They had spent the last 69 hours on FaceTime with their mom, knowing the end of her life was near.“Facetime makes this noise when it closes out and it closes out immediately, it doesn’t go to a corner and fade away. So, my mom just disappeared. There was this noise and she was pulled back into the universe,” Laurie said via a Zoom call from her home in California.Just weeks earlier, Joanne, 82, was enjoying her evening vodka martini at Laurie’s home where she’d been living. The 82-year-old had some underlying health issues but for the most part was doing okay, until one day when she started suffering from shortness of breath.Knowing what she knows now, Laurie says she likely would’ve never let her mom be checked into a short-term care facility after being discharged from a local emergency room.“It didn’t occur to me at all that this was still running through nursing homes like that,” she explained.When Joanne was checked into York Healthcare & Wellness Centre in Highland Park, California, not a single person had COVID-19. But just days later, dozens of patients had suddenly contracted the virus. After testing positive, Joanne’s condition quickly went downhill.“I couldn’t rescue her. Had I known what would happen, I would’ve gotten her a hotel room and hired a nurse,” Laurie lamented.By the time it became clear that Joanne wasn’t going to survive the virus, doctors set up an iPad in her room. Laurie and other family members would spend hours just watching their mom breath, offering words of comfort at any hint of movement. All of it done virtually in an attempt to keep the virus from spreading.COVID-19 has robbed families of the opportunity to grieve together in person.“My mom got the worst send off and at the end we were only voices that we hoped she could hear. It’s a terrible way to say goodbye to somebody, it doesn’t feel real,” Laurie said about her mom’s death.But Laurie has tried to find some purpose in her pain. As a professional comedian with a large online social media following, she decided to chronicle her mom’s final days of Twitter. It was an effort, she said, to educate the public about the true scope of the kind of suffering the virus causes. Laurie has even used her platform to criticize people who push back against mask-wearing policies.“To someone who doesn’t want to wear a mask, you’re incredibly selfish, you’re harming yourself. Even if you think, ‘Oh it’s just old people,’ do you want to lose an old person like this? Is this how you want your grandma or grandpa to go out? Is that fair?” she questioned.Having watched her mother take her final few breaths via a FaceTime call, Laurie is left to wonder why so many states are reopening as quickly as they have, even as COVID-19 cases continue to spike.“There’s over 100,000 stories like mine, and 100,000 families like mine that are shocked and numb, you could be me pretty soon.” 3397

After a bad night’s sleep, most people reach for a large mug of black coffee. Researchers say that’s probably not a good idea.Researchers at the University of Bath in the United Kingdom looked at the impact of having a bad night’s sleep and morning coffee. They found a cup of coffee on an empty stomach could impair control of blood sugar levels.Some good news, the scientists, writing in the British Journal of Nutrition, say that one night of poor sleep has a limited impact on a person’s metabolism when compared to a normal night sleep.However, drinking coffee first thing can have a negative effect on glucose metabolism by around 50 percent, researchers found.“We know that nearly half of us will wake in the morning and, before doing anything else, drink coffee – intuitively the more tired we feel, the stronger the coffee,” said Professor James Betts, Co-Director of the Centre for Nutrition, Exercise and Metabolism at the University of Bath who oversaw the work.Study participants underwent tests where they had either normal or disrupted nights sleep, followed by coffee or a glucose drink representing the calories in an average carbohydrate breakfast about an hour after they woke up.Then their glucose and insulin levels were taken.“Put simply, our blood sugar control is impaired when the first thing our bodies come into contact with is coffee especially after a night of disrupted sleep. We might improve this by eating first and then drinking coffee later if we feel we still need it. Knowing this can have important health benefits for us all,” Betts said.Keeping blood sugar levels within a healthy range can reduce the risk of diabetes, heart disease and other diseases. 1701
