HAMPTON ROADS, Va. - A new study shows that teens who use vaping devices or e-cigarettes could be at an elevated risk for contracting COVID-19."Maybe they have been in contact with contaminated surfaces or it's been a while since they washed their hands, then they bring a device to their mouth; there are many risks," said Dr. Danielle Lecky-Chadhuri with Pediatric Partners of Hampton Roads.She says young people may think their age protects them from getting coronavirus, but that is not true."Smoking is going to increase receptors in the lungs lining that COVID and or other viruses like influenza can attach to and cause further inflammation," said Lecky-Chaudhuri.A new study by Stanford University School of Medicine published in August found that teens were five to seven times more likely to experience COVID-19 symptoms like coughing, fever, and shortness of breath compared to those who never smoked or vaped."Even the ones that are nicotine-free have been shown to have traces and small amounts of nicotine in them," she said.Lecky-Chaudhuri says teens are more vulnerable to nicotine dependence."Certainly the younger they are, the brain is not matured, and that would increase sustainability to be addicted and dependent," she said.Nicotine isn't the only danger of using e-cigarettes."We have seen injuries from burns, explosions, chemical injuries as well as nicotine exposure and overdose," she said.Lecky-Chaudhuri recommends talking to your children about acute and long-term effects – perhaps listing reasons that would relate well to them."Maybe tell them they may not like the way their hair and my clothes smell and that they could be at an increased risk of staining their teeth or decreased athletic performance."This story was first reported by Chelsea Donovan at WTKR in Norfolk, Virginia. 1825

Holidays will look different this year for many Americans, with dinners outside, social distancing, or passing on family gatherings altogether. But several companies developing rapid at-home COVID-19 tests are hopeful that won't be the case next year. The goal is to make inexpensive, easy-to-use COVID tests that can deliver results in minutes, just like a pregnancy test. "For people to feel comfortable to associate with friends or family, there needs to be a testing methodology ideally that can be performed at home," said Tony Lemmo, CEO of the manufacturing company BioDot.The company's technology is being used by over 70 manufacturers worldwide making COVID-19 antigen, antibody, and PCR tests. Their automated platforms dispense nanoliter/picoliter amounts of reagent onto the tests accurately and fast.Lemmo says just one of their systems can support the production of roughly 100 million COVID-19 tests per year, helping to make high-volume production possible.“We knew we were going to be called on by customers to manufacture more equipment to provide them the ability to manufacture more tests," said Lemmo. To meet customer demand, BioDot increased staffing and built a new facility, compressing production time from months to weeks. The FDA recently authorized the first rapid at-home test that can deliver results in 30 minutes, eliminating the need for a lab to test the sample. But the molecular single-use test will only be available to patients with a doctor's prescription who are suspected of being infected with COVID-19.Companies developing tests hope the FDA will soon authorize another at-home testing tool: the rapid antigen test.These inexpensive tests provide results within minutes, and companies developing them say millions could be sold without a doctor's referral.“From what we’re hearing, it’s really just a matter of possibly months before there’s at least sufficient data to be able to support an at-home use of a test like an antigen test," said Lemmo.Lemmo says if authorized by the FDA, manufacturers could make millions of these tests in a matter of months. But antigen tests are less accurate, and the FDA wants to ensure they'll be simple enough for people to use at home. There are also concerns over how the data will be reported to health authorities. “I think any at-home testing or massive rollout of a test into the communities needs to be done very carefully and with a lot of education around it," said Clinical Lab Director Melissa Miller. Dr. Miller is a professor of pathology and laboratory medicine at the University of North Carolina Chapel Hill and Medical Director for the Clinical Microbiology Lab for the Medical Center.She worries the inaccuracies of these tests could eventually lead the public to lose trust in all testing. “Even at 98 percent specificity, which is very, very high. That means you’re going to have a false positive two out of every 100. If you started testing a hundred million people, this is millions of people who have a false-positive test," said Dr. Miller. She says this could lead to healthy people isolating and missing work or school unnecessarily, and false-negative results could give people a false sense of security. “These rapid antigen tests were pushed out to skilled nursing facilities; this is a very high-risk patient population. This is actually where you want a very accurate test," said Dr. Miller. She says it’s unclear how well antigen tests detect the virus in asymptomatic patients but agrees more data is needed to figure that out.“It might make more sense for K-12 schools, or even college settings, where there’s less risk for a poor outcome if you have a false positive or a false negative," said Dr. Miller. But with a growing demand for convenient at-home testing, manufacturers are hopeful that in the months ahead, the FDA will soon open the door to new solutions. 3889

Half of the coral populations in the Great Barrier Reef off Australia’s coast have been killed off because of warming ocean waters, a new study says.Between 25-30 percent of all marine species rely on coral reefs at some point in their life cycle. The Great Barrier Reef is the world’s largest coral reef, covering nearly 133,000 square miles.It has more than 411 species of hard corals documented, as well as 1,500 species of fish and other animals.Researchers looking at coral populations over 30 years starting in 1995 found there was decline in both shallow and deeper water, and across different species. They said two in particular, branching and table-shaped corals, were especially hard hit in 2016 and 2017 because of record-breaking temperatures.The study finds climate change to be a key driver in reef disturbances that disrupt recovery.“The potential for recovery of older fecund corals is uncertain given the increasing frequency and intensity of disturbance events. The systematic decline in smaller colonies across regions, habitats and taxa, suggests that a decline in recruitment has further eroded the recovery potential and resilience of coral populations,” the researchers note.They also say the coral that spawn the larvae that makes more coral have declined dramatically over large stretches of the reef.“Corals are tremendously resilient because of their capacity to produce millions of babies but they/we desperately need a break from disturbances,” Andreas Dietzel, a professor at the ARC Center and a co-author of the paper, said in an email to the Washington Post. 1600

HONOLULU (AP) — A couple who authorities say knowingly had COVID-19 but boarded a United Airlines flight from San Francisco to Lihue, Hawaii, anyway, have been banned from the airline.In an email to E.W. Scripps, a spokesman for United told the newspaper that they banned the couple while "they investigate the matter.""The health and safety of our employees and customers is our highest priority, which is why we have various policies and procedures in place as part of a multi-layered approach to create a safer travel environment, including mandating that everyone onboard wears a mask," the statement read. "Prior to traveling, all United customers are required to complete a ‘Ready to Fly’ checklist acknowledging they have not been diagnosed with COVID-19 in the last 14 days. We have banned these customers while we investigate this matter."The Kauai Police Department says Wesley Moribe and Courtney Peterson were arrested after they boarded a United flight home to Lihue with a 4-year-old child after San Francisco International Airport officials told them to isolate themselves and avoid the flight Sunday. Officials say Moribe and Peterson took COVID-19 detection tests and both knew they tested positive for the virus.“They knowingly boarded a flight aware of their positive covid-19 test results, placing the passengers of the flight in danger of death,” the Kauai police spokesperson, Coco Zickos, told the Washington Post.The Kauai residents were arrested on suspicion of second-degree reckless endangering. The child was released to the care of family members. The child's relationship to Moribe and Peterson was not disclosed."We continue to request visitors and residents alike to follow the Governor's Emergency Rules and take all necessary precautions to prevent the spread of COVID-19," Kaua'i Police Chief Todd Raybuck said in the news release.Peterson did not immediately return voicemail messages from the Associated Press seeking comment. A phone number associated with Moribe had been disconnected.If found guilty, Moribe and Peterson could face up to a year in jail and a ,000 fine. 2120

Grocery stores are preparing for more shortages and two chains have already announced limits on buying some items.Kroger is allowing customers two each of paper towels, toilet paper, disinfecting wipes and hand soap. H-E-B is putting limits on those same things, along with rubbing alcohol, and first aid and cleaning gloves.A supply chain expert tells us the upcoming holidays and a recent surge in COVID-19 cases are adding to demand.Manufacturers are focusing on the most popular products, so less variety may also make it seem like there are more shortages.Months of steady demand has made it tough for retailers to stock up.“There hasn't been really a low season across the board to allow for building up inventory that we can use during the holiday season when we expect a surge in demand,” said Rafay Ishfaq, Associate Professor of Supply Chain Management at Auburn University.Another chain, Stew Leonard's, says it's ordering 20% more stock than usual before the holidays this year. Meanwhile, it's already seen an uptick in panic buying.Customers are looking for cleaning supplies, frozen foods and comfort foods.“I think there was a little unrest over the election and there still is, and people aren't really sure if there's going to be any type of a lockdown in America,” said Stew Leonard's CEO Stew Leonard Jr.In talking to customers, Stew Leonard's says it's found more people are preparing for small Thanksgiving gatherings. So, it's stocking up on smaller turkeys and offering recipes to people who are trying a hand at cooking one for the first time.By anticipating the changes, the chain hopes to keep shelves full through the end of the year. 1670
