A white woman derisively labeled "Cornerstore Caroline" on social media has apologized after video of her appearing to call New York police to say a 9-year-old black boy grabbed her behind was posted online."Young man, I don't know your name, but I'm sorry," the woman told TV reporters this week after watching surveillance footage that showed the child's backpack brushing up against her backside -- his hands in plain sight -- as she leaned over a Brooklyn deli counter.Cellphone video of the public apology also circulated across social media.Before Friday's mea culpa, however, Teresa Klein was widely ridiculed on social media after a viral video of the incident became the latest example of whites calling the police on blacks over seemingly trivial reasons.The episode began Wednesday when Klein appeared to be calling the police on cellphone video captured by a Brooklynite who posted it to Facebook with the message, "Make this go viral. Meet Cornerstore Caroline." 983

After issuing previous guidance that encouraged schools to close in areas with high transmission of the coronavirus, the CDC is now emphasizing that schools reopen this fall.The guidance issued on Thursday is in line with a Trump administration priority to reopen schools this fall.“It is critically important for our public health to open schools this fall,” said CDC Director Dr. Robert R. Redfield. “The CDC resources released today will help parents, teachers and administrators make practical, safety-focused decisions as this school year begins. I know this has been a difficult time for our Nation’s families. School closures have disrupted normal ways of life for children and parents, and they have had negative health consequences on our youth. CDC is prepared to work with K-12 schools to safely reopen while protecting the most vulnerable.”Now in areas with, as the CDC calls it, "substantial, uncontrolled transmission" of the coronavirus, "Schools should work closely with local health officials to make decisions on whether to maintain school operations. The health, safety, and wellbeing of students, teachers, staff and their families is the most important consideration in determining whether school closure is a necessary step. Communities can support schools staying open by implementing strategies that decrease a community’s level of transmission. However, if community transmission levels cannot be decreased, school closure is an important consideration."In areas with substantial, controlled transmission, "Significant mitigation strategies are necessary." In addition, social distancing and face covering policies should be implemented, the CDC said.Previous guidance called for schools in areas with substantial community transmission (the CDC did not distinguish between uncontrolled or controlled) to, "Implement extended school dismissals (e.g., dismissals for longer than two weeks). This longer-term, and likely broader-reaching, dismissal strategy is intended to slow transmission rates of COVID-19 in the community. During extended school dismissals, also cancel extracurricular group activities, school-based afterschool programs, and large events."In previous guidance, the CDC called on schools to keep students 6 feet apart. But many classrooms do not have the space to properly socially distance students. The Trump administration’s response appears to be a 5 billion request to Congress. President Donald Trump said that the funds, in part, could be used for schools to open additional spaces and hire additional staff in order to help space students.The CDC said that the “best available evidence from countries that have opened schools indicates that COVID-19 poses low risks to school-aged children, at least in areas with low community transmission, and suggests that children are unlikely to be major drivers of the spread of the virus.”But that guidance contradicts a South Korean study published by the CDC earlier this week.The study said that while children under age 9 were less likely to spread the virus, youth ages 10 through 19 were just as likely as adults of spreading the virus.The study also found that closing schools in several Chinese cities, including Wuhan, that school closures and social distancing significantly reduced the rate of COVID-19 among contacts of school-aged children.“The role of household transmission of SARS-CoV-2 amid reopening of schools and loosening of social distancing underscores the need for a time-sensitive epidemiologic study to guide public health policy,” the researchers wrote.In its new guidance, the CDC said that extended school closures are harmful to children and can lead to severe learning loss, and the need for in-person instruction is particularly important for students with heightened behavioral needs.The American Federation of Teachers this week pointed toward a three-point plan that the US should implement for reopening schools.“Our plan details three conditions essential for schools to reopen,” wrote Randi Weingarten, president of the American Federation of Teachers. “First, the average daily community infection rate among those tested for the coronavirus must be very low. (New York Gov. Andrew Cuomo has required the rate not to exceed 5 percent for at least 14 days.) Second, schools must employ public health protocols, including 6-feet social distancing, masks, deep cleaning and handwashing stations. Third, adequate resources must be available to enact these safeguards, including funding for additional nurses, guidance counselors and teachers to reduce class size.”But the CDC also weighed the concerns of the coronavirus against providing physical activity, food and safety for students. The CDC said studies project that the childhood obesity rate would increase by 2.4% if schools remained closed through December.This guidance comes as cases in the US steadily increased earlier this month, prompting coronavirus death counts to rise in recent days. The US had back to back days of more than 1,000 people reportedly dying from coronavirus-related illnesses, according to Johns Hopkins University.To read the CDC’s latest guidance, click here. 5184

ALPINE COUNTY, Calif. – One small county in California has become a safe haven from the coronavirus. There’s only been one reported case of COVID-19 since the start of the pandemic, but now, hundreds of visitors from across the country are going there to vacation.“I have never seen this many people here,” said Deanna Jang, the owner of the general store in the county.Business owners like Jang worry the visitors they rely on may bring more problems than profit. “It’s been very good for business, it’s scary though because you just don’t know what’s going to happen,” said Jang.Jang’s family has owned a local general store for decades. She’s nervously watching as cases rise in counties all around hers. She fears a summer shutdown in this tourist town could take her family business with it.“You need to make your year’s income here in two months because the rest of the months you just kind of get by,” she said. “It’s scary, it’s like, ‘What does this mean for next year, and the year after?’ Because we’d have to recover from that.”“It’s sort of a double-edged sword of wanting to get our economy started and worrying that the people who are supporting the economy are going to bring COVID into our community,” said Nichole Williamson of the Alpine County Health Department.Williamson said the worry has locals considering what would typically be unthinkable there. “We have had people who work in the short-term rental business tell us they would not be upset if we limited short-term rentals right now,” she said.One driving concern: the county has few medical resources.“We have no private physicians, no hospitals, and we have a two-day a week family clinic with a nurse practitioner, and she was called up into active duty in the Army,” said Williamson.First responders are also in short supply. “If we had a few law enforcement and a few firefighters exposed, we’d be in a very vulnerable situation,” said Williamson.But with this vulnerability comes a choice: to fear the virus or face it. “You just have to learn to live with it,” said Jang.For hotel owner John Flannigan, there is no choice. He said he is making safety his top priority to make sure his business can stay open. “The economy is in its worst case,” said Flannigan. “It’s worse than 2001 and 2008 combined, times ten, so I don’t think we should be hurting anyone’s ability to make a living. I think we should be figuring out solutions so they can make a living.” Flannigan runs Sorenson’s Resort and has moved all his dining to be outdoor, open air and is making sure guests have space to spread out and social distance.As worried as many community members are, they hope they can keep business going safely.“It’s not about me. It’s not about you. It’s about everyone,” said Jang. 2769

  

After two and a half weeks of historic destruction, the Camp Fire in Northern California is 100% contained, but the search for remains threatens to push the death toll over 85, where it stood early Sunday.It's already the state's deadliest fire.Officials found two bodies in Paradise and another in Magalia, both of which sit just west of the Plumas National Forest, roughly 100 miles north of Sacramento.Since it began November 8, the fire has destroyed almost 14,000 homes, 514 businesses and 4,265 other buildings. It has covered more than 153,000 acres, roughly the size of Chicago.Cal Fire, the state's forestry and fire protection agency, announced the fire was completely contained early Sunday. As of Saturday evening, the uncontained portion of the fire was along steep terrain unsafe for firefighters due to recent heavy rains, the agency said.More than 2,500 people are now accounted for, according to the Butte County Sheriff's Office. While 251 people remain missing, the sheriff's office says, that number is down from more than 1,000 just a few days ago.The sheriff's office is maintaining a public list of missing people and offering to swab the cheeks of immediate relatives in hopes of identifying those lost in the fire. 1247

  

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.
