With COVID-19 cases surging across the country, public health officials and ICU doctors are pleading with Americans to reconsider gathering with family members ahead of the Thanksgiving holiday for fear of spreading the virus even further.“We really don’t have a national or even multi-state plan, and that worries me,” said Dr. Stephen Morse with Columbia University.While he strongly recommends against it, Dr. Morse knows inevitably some people will still get together on Thursday. His advice is to have a multi-layered safety approach.The first layer involves testing. He’s urging people to avoid those rapid tests if they can because they’re less accurate.With so many Americans trying to get tested right now, officials also say it’s important to plan ahead and be prepared to potentially not get results back before Thanksgiving.“Testing is really important because it’s the only way we can find people who aren’t obviously sick and stop them,” Dr. Morse added.Health officials say if you are planning a small family gathering, get tested before you see high-risk family members. Americans are also being urged to consider virtual holiday gatherings whenever possible.If you are gathering with people outside your household, eat in separate rooms or consider eating outdoors.“What I’ve seen is once it gets into a family, because we let our guard down around our family, everybody gets infected,” explained Dr. John Coleman, who works in the ICU at Northwestern University’s teaching hospital in Chicago.Dr. Coleman says there are just too many variables to consider when it comes to gathering for Thanksgiving this year.“I think we are on the cusp of some very, very dark months. What we’ve seen is the increase of COVID across the nation is going to eventually stress the health system.” 1804

White House comms director Alyssa Farah says a document claiming ending the pandemic was an administration accomplishment was “poorly worded.” She says President Trump does not believe the pandemic is over. “The intent was to say that it is our goal to end the virus.”— Kaitlan Collins (@kaitlancollins) October 28, 2020 328

With millions of Americans getting tested for COVID-19 every single day, some are struggling with long waits for results.But now, researchers say there’s a much easier and faster way to test for the virus, and its right under your nose.“You scratch it, smell it, and then you have a choice of these different windows and you pick which one,” said Derek Toomre, Ph.D., a professor at Yale University School of Medicine.Toomre is part of U-Smell-It, a team that created a scratch-and-sniff app to help determine if someone has COVID-19 all through the sense of smell.“It's going to see how good your sense of smell is and if you do really well, you’ll pass,” Toomre said. “And if you don’t, it will say, ‘hey, you got something up.’”Despite being less accurate than a COVID-19 diagnostic test, this product is much faster and less costly. With results available in less than a minute and the cards costing 50 cents a pop, scientists say this smell app could outperform traditional tests at a fraction of the price.“We’re all familiar with the idea of testing people for fever as a way of finding people who have COVID,” said Roy Parker, Ph.D. a biochemistry professor at the University of Colorado, Boulder. “But that hasn’t worked very well.”Parker says with only about 20% of people with COVID-19 getting a fever, compared to 80% of people with COVID-19 reporting a loss a smell, a smell test is a much better indicator of COVID-19 infection than a temperature check.“It would make a big difference because you would identify people who have COVID, but they have such mild symptoms that they don’t know it and they’re out walking around potentially infecting other people and their family,” Park said.While commercially available, U-Smell-It is now looking for emergency FDA approval with the goal of getting their scratch-and-sniff cards into people’s hands and under their noses as quick as possible.“I can see people saying, ‘hey, this is not serious,’ and that’s fine, don’t take it serious,” Toomre said. “Let’s just try to do it and see if it works. And if you can’t smell that test and it’s saying, ‘hey, there’s something up’ well, you know, you should isolate and check out.” 2192

  

While kids are on summer break, districts across the country are working to determine whether or not to reopen schools, and how to do it safely.School leaders are racing the clock to figure out what the next school year will look like.“We’ve been looking at how can we provide a high quality education in this environment,” said Lisa Yates, Superintendent at Buena Vista School District.For Yates, that decision is simple.“We’re hearing that from families, we’re hearing that from students, we want to be back in school,” she said.At Buena Vista Middle and High School in the Colorado mountains, summer school is in session at their brand new, still under construction, building. Students and teachers are piloting a new platform that leaders hope will help come fall.The platform was installed in early June and created by tech company Wolk. It works like this -- first, gateways are installed in classroom ceilings.“The system is called Open,” said Rene Otto, Solutions Architect for Wolk.com.Next, students and teachers put on a wearable device at the beginning of the school day. “They’re given these safety cards or wristbands, so what these do is they act as beacons,” she explained.The devices currently use Bluetooth to communicate. Using the gateways, the software shows when a beacon comes within a certain amount of space of another beacon, for how long, and if the beacon moves rooms.“The point of it was to help people understand where they are in a physical space, so we can figure out if safe social distancing is being practiced,” Otto said.The school district’s technology coordinator, Matt Brooker, helped install the system. “If we did have an incident where a kid is positive, could we do contact tracing with this?” he said.For students, the idea seems simple enough.“It’s going to record where you walk and how close you get to other people,” 6th grade Aidan explained. “It’s like wearing a little necklace. It doesn’t really bother me that much.” Others weren’t as convinced. “Personally, I don’t know if a lot of people are going to want to wear them,” 10th grader Taylor said.With every tracking device comes concerns over data and privacy.“It took me a little bit,” said Reba Jackson, a teacher at the school. “I’m a little paranoid about tracking things.”“I went from feeling like it might be a little bit invasive,” teacher Robin Fritsch, explained. “It’s not a big deal. If it gives us valuable data, I’m in.”Otto said not to worry.“We really want to make sure privacy is protected. So the way it works is, only the administrators of the schools have access to the identifying information,” she explained. In other words, each tracker has a number as the identifying name. Only school admin members are able to match that number with a student. “I don’t think any parents or people want to be tracked by a technology company generally. But if that information can help make people safer, I think it’s valuable.”Otto said for the system to work fully, they need at least 60% of students and teachers using it. This helps find hot spots that potentially need more cleaning or more attention to create a better socially distanced space.“I think it’s going to be a valuable tool,” Fritsch said.As students come back, the hope is that the system will help identify who has come into contact with someone who tested positive for COVID-19, and stop the spread there. This could mean the difference between sending 10 kids home and sending the entire school home in the event of a positive case.“Typically rural communities, as far as economic development, don’t have the resources the major metropolitan areas might have,” said Wendell Pryor, Director of Chaffee County Economic Development Corporation. “So any tool like this that aids in the threat of an outbreak and the way it might spread, I think is going to be a bonus to everybody involved.”“In person is where we want to be, so we’re putting our resources there,” Superintendent Yates said. 3979

  

While we’re still waiting on a comprehensive COVID-19 vaccine distribution plan, the Johns Hopkins Center for Health Security released an ethics framework Wednesday for who it says should be prioritized.There are two tiers of groups it says should go before the general public. No surprise, the first tier includes front line health care workers taking care of coronavirus patients, people over 65, those with underlying health conditions and their caregivers.Also noted are people who work in the vaccine industry and those who will be administering them. Also, school, food supply and public transportation workers.One issue with that first tier is that's a lot of people, more than 90 million by some estimates.“So, it’s quite possible when a vaccine is available, there won’t be enough available for everybody in this top tier and so there may need to be prioritization within this top tier,” said Dr. Eric Toner, senior scholar at the Johns Hopkins Center for Health Security.The second-tier group includes other health care workers, people living in remote locations without access to quality care, and other essential workers like delivery, military, and first responders.It also includes people who live in places where they can’t socially distance, so inmates and people in shelters.The framework also mentions this is a decision that shouldn't only be made by experts and officials.“The public needs an opportunity to weigh in on this because, after all, they are the ones who are the recipients of the vaccines and whether they get it or not,” said Toner.The good news is the scholars don't see cost as a barrier to the vaccine. And while a vaccine is the best hope for controlling the pandemic, it will not be a magic bullet right away.“If we have a vaccine sometime this winter that’s authorized, it will be many months before everybody has access to it,” said Toner.Some decisions about who gets the vaccine first can't be made until one is ready, because you need to know how it may impact groups like the elderly or pregnant women. 2055
