URBANA-CHAMPAIGN, Ill. – As colleges and universities are tasked with safely beginning classes, researchers at one school are ramping up testing. But they're putting away the nasal swab in exchange for a test they say can be scaled to perform thousands of tests a day with turnaround in just hours.College junior Alliyah Rumbolt-Lemond is already back on campus and regularly testing for COVID-19.“I know if you have in-person classes, you're going to be on campus, you have to get tested twice a week,” she says.The college junior is one of the more than 51,000 students at the University of Illinois at Urbana-Champaign returning to school during the pandemic, posing a logistical challenge for administrators.“It was very daunting,” said U of I chemistry professor Marty Burke.He was part of the team of university researchers who developed a two-step saliva-based COVID-19 test to tackle the problem.“We called this our ‘target, test and tell’ initiative, overall collectively described as a ‘Shield.’”The Shield Initiative needed to be scalable, and unlike the four-step nasopharyngeal swab tests, not vulnerable to supply chain bottlenecks.“It's a very powerful concept that if we can get to that fast, frequent testing, we really could get control of the situation,” said Burke.A quick stop on route to class or work, integrated with local health care agencies, students receive results on an app within hours, not days.“It takes about five to ten minutes to submit your saliva sample and then the results are typically back on your phone within three to six hours,” said Burke.The university’s veterinary school diagnostic lab has been converted into a full-scale human COVID-19 testing facility. It’s capable of processing some 10 to 20,0000 saliva tests per day.“I want to hang out with friends and do it the right way, like following CDC guidelines,” said Alliyah. “But I feel more comfortable saying ‘hey when's the last time you got tested?’”A total of 20 testing sites with 40 stations are set up across campus. Users can even get exposure notifications if they’ve been in contact with someone who tests positive.“If someone tests positive then same day that person is isolated,” said Burke. “Which we think is critical for ultimately the efficacy of the testing program.”They’ve published a pre-print paper on their COVID-19 saliva test, which is undergoing peer review and are seeking FDA approval.For students like Alliyah, it’s one-stop piece of mind.“It makes you feel like I'm safer on campus because even though we only have to get tested twice a week you can get tested every day the testing site is open if you wanted to.” 2653

Vaping by U.S. teenagers fell dramatically this year, especially among middle schoolers, according to a federal report released Wednesday.Experts think last year’s outbreak of vaping related illnesses and deaths may have scared off some kids, but they believe other factors contributed to the drop, including higher age limits and flavor bans.In a national survey, just under 20% of high school students and 5% of middle school students said they were recent users of electronic cigarettes and other vaping products. That marks a big decline from a similar survey last year that found about 28% of high school students and 11% of middle school students recently vaped.The survey suggests that the number of school kids who vape fell by 1.8 million in a year, from 5.4 million to 3.6 million, officials said.But even as teen use declined, the report shows a big bump in use of disposable e-cigarettes. The Food and Drug Administration earlier this year barred flavors from small vaping devices like Juul and others that are mainly used by minors. The policy did not apply to disposable e-cigarettes, which can still contain sweet, candylike flavors.“As long as any flavored e-cigarettes are left on the market, kids will get their hands on them and we will not solve this crisis,” Matt Myers of the Campaign for Tobacco Free Kids said in a statement.The national survey is conducted at schools each year by the Centers for Disease Control and Prevention and usually involves about 20,000 middle and high school students. It asks students if they had used any vaping or traditional tobacco products in the previous month. The survey was cut short this year as schools closed because of the coronavirus pandemic.Federal health officials believe measures like public health media campaigns, price increase and sales restrictions deserve credit for the vaping decline. The age limit for sales in now 21.But they also acknowledge the outbreak probably played a part. The CDC’s Brian King said sales started falling in August — when national media coverage of the outbreak intensified.“It’s possible that some of the heightened awareness could have influenced decline in use,” said King.By the time the outbreak was winding down early this year, more than 2,800 illnesses and 68 deaths had been reported. Most of those who got sick said they vaped solutions containing THC, the ingredient that produces a high in marijuana. CDC officials gradually focused their investigation on black market THC cartridges, and on a chemical compound called vitamin E acetate that had been added to illicit THC vaping liquids.Kenneth Warner, a professor emeritus at the University of Michigan’s school of public health, said the teen vaping drop was larger than expected.“This does look like a very substantial decrease in a single year and it’s very encouraging,” said Warner, a tobacco control expert.Among the likely factors, Warner noted the general negative publicity surrounding vaping. Additionally, Juul preemptively pulled all its vaping flavors except menthol and tobacco last fall ahead of federal action.Warner and other researchers have tracked a recent decline in teen smoking to all-time lows — about 6% — even as vaping has increased. He said it will be critical to watch whether teen smoking begins rising again as fewer teens vape.The new figures were disclosed on the same day that all U.S. vaping manufacturers faced a long-delayed deadline to submit their products for FDA review. Generally, that means the vaping companies must show that their products help smokers reduce or quit their use of cigarettes and other tobacco products.E-cigarettes first appeared in the U.S. more than a decade ago and have grown in popularity with minimal federal regulation.___Perrone contributed from Washington.___The Associated Press Health & Science Department receives support from the Howard Hughes Medical Institute’s Department of Science Education.

Two dozen workers at an Amazon fulfillment center in New Jersey were taken to hospitals Wednesday after an aerosol canister of bear repellent fell off a shelf and discharged fumes inside the building, a spokesperson for Robbinsville Township told CNN, citing a preliminary investigation.Employees reported experiencing difficulty breathing and burning sensations in their eyes and throat, said John Nalbone, spokesperson for Robbinsville Township, where the fulfillment center is located.Emergency personnel responded to a morning 911 call that 54 workers at the fulfillment center were experiencing symptoms, Nalbone said. Twenty-four workers were taken to local hospitals, including one in critical condition, he said.It appears to be an accidental dispersal, he said, adding EMS is still on scene conducting triage.Bear repellent spray is similar to a can of pepper spray and is intended to deter an aggressive or charging bear. The US Fish and Wildlife Service recommends bear repellent spray as both safer and more effective than a firearm in fending off bear attacks.Rachael Lighty, regional manager for external communications for Amazon Operations, said a damaged canister caused the problem."Today at our Robbinsville fulfillment center, a damaged aerosol can dispensed strong fumes in a contained area of the facility," she said."The safety of our employees is our top priority, and as such, all employees in that area have been relocated to safe place and employees experiencing symptoms are being treated onsite. As a precaution, some employees have been transported to local hospitals for evaluation and treatment. We appreciate the swift response of our local responders."Nalbone said the call came in at approximately 8:50 a.m. to the Robbinsville EMS/911 system. One wing of the 1.3 million square foot center was evacuated, he added. 1858
