This week, experts are sending warnings to those considering seeing people outside their household without quarantining first. One aerosol expert weighs in on just how dangerous the holiday could be."My simplest advice is it is not a good idea to meet with people outside of your household for a holiday meal. That’s the most important message that can be underscored, and the reason for that is there are multiple ways this virus can be transferred,” said Alex Huffman, an aerosol expert and associate professor at the University of Denver. “The closer you are increases the chances of that, but aerosols can come out of your mouth and mix into the room. The longer you're in that room, the more chance you have of getting sick.”Huffman says time, ventilation and proximity have a big impact on whether coronavirus droplets can spread and infect others."When you breathe and talk, the louder you talk, droplets and aerosols come out of your mouth. So, traditionally, droplets are on the bigger side, aerosols are on the smaller side," said Huffman.With no mask on, these droplets can land on the faces of people around you or on their plates."And so, the biggest danger with the Thanksgiving meal or holiday meal or any meal specifically, restaurants included, are that you have to take off your mask to eat and that is why eating together indoors is so dangerous," said Huffman.Huffman demonstrated how fast droplets can spread in the air by showing how quickly food coloring can spread in water. He also analyzed the risks of eating a Thanksgiving meal in person, taking commonly-used models and applying varying factors that come into play when eating with people outside of your household."And then, I used the same model to say, ‘What happens if we meet for holiday meals?’ Let's say we have 10 people. We all eat for two hours. We all don't have masks on, and then, we ran different scenarios. If it was a small room, a large room, a medium-sized room and then estimate the amount of risk that would be from aerosol," said Huffman.Matching with community transmission rates, Huffman estimated that the probability of each person at the table having COVID-19 was about 5 percent."If it's a small room, everybody has something like a 15 percent chance of getting infected, even if we had no idea if anybody was infected or not. If it's a big room, it's a little bit less than that," explained Huffman.Ventilation also comes into play, which is why experts are advising that if you really are planning to meet with family this holiday, do it outside. Opening windows and doors also helps. Huffman also has some tools people can use, such as a carbon dioxide monitor or you can create your own box fan air filter."On the back, this is a furnace filter that’s also 20 inches and so you tape them together so they're well-sealed. You turn it on high and you blow the air through this filter and that removes the particles in the room that could potentially contain virus in it," said Huffman.Still, Huffman and other medical experts agree this won't completely eliminate the risk of spreading COVID-19. The safest thing to do is stay home and avoid celebrating Thanksgiving with people who are not part of your household. 3230

There was a “concerning” increase in the number of drug overdoses in the US in from March through May 2020, the Centers for Disease Control and Prevention said on Thursday.The data were part of an annual analysis of drug overdoses in the US. The data went from June 2019 through May 2020. The CDC noted that pre-pandemic drug overdoses were up in the month preceding the pandemic, but increased further when much of the US economy closed to stop the spread of the virus in March.The CDC previously estimated that 19,416 Americans died from drug overdoses from January through March 2020, which was up nearly 3,000 deaths. Approximately 81,230 drug overdose deaths occurred in the United States in the 12-months ending in May 2020, the CDC reported. For the year ending in May, there were nearly 10,000 additional drug overdose deaths compared to the previous year.The CDC said that synthetic opioids, primarily illicitly manufactured fentanyl likely drove the increase. The American Medical Association says that there has been a 37% drop in prescriptions of opioids since 2014.“The increase in overdose deaths is concerning.” said Deb Houry, M.D., M.P.H., director of CDC’s National Center for Injury Prevention and Control. “CDC’s Injury Center continues to help and support communities responding to the evolving overdose crisis. Our priority is to do everything we can to equip people on the ground to save lives in their communities.”The CDC issued a set of recommendations to help combat drug overdoses:Expand distribution and use of naloxone and overdose prevention education.Expand awareness about and access to and availability of treatment for substance use disorders.Intervene early with individuals at highest risk for overdose.Improve detection of overdose outbreaks to facilitate more effective response.The CDC added that “Measures taken at the national, state, and local level to address the COVID-19 pandemic may have unintended consequences for substance use and overdose, but CDC is working with states, territories, tribes, cities, and counties across the country to continue drug overdose surveillance and prevention efforts.”During the same timeframe of March through May 2020, more than 67,000 Americans died from the coronavirus despite intense mitigation efforts, according to Johns Hopkins University data. The death tolls from the coronavirus and drug overdoses show the challenge public health officials face in keeping the country healthy amid a pandemic.“The disruption to daily life due to the COVID-19 pandemic has hit those with substance use disorder hard,” said CDC Director Robert Redfield, M.D. “As we continue the fight to end this pandemic, it’s important to not lose sight of different groups being affected in other ways. We need to take care of people suffering from unintended consequences.” 2842

TOKYO (AP) — The five Olympic rings are back in Tokyo Bay. The rings were removed for maintenance four months ago shortly after the Tokyo Olympics were postponed until next year because of the COVID-19 pandemic. The rings are positioned on a barge and stand about 15 meters tall and 33 meters in length — about 50 feet tall and 100 feet in length. The Olympic rings will be lighted at night and are situated in the shadow of Tokyo's famous Rainbow Bridge. The Olympics are to open on July 23, 2021, followed by the Paralympics on Aug. 24. Organizers are confident that 15,400 Olympic and Paralympic athletes can safely enter Japan during the pandemic. 659

There are 725 days until the 2020 presidential election.  “I know people think it's a long way out, but the reality is the Iowa caucuses are likely to be 15 months from now, if not sooner,” says Dr. Lara Brown, the director of the Graduate School of Political Management at George Washington University.Iowa is key. Several high-profile Democrats have already visited the state recently, and experts say it won't be long until some of them officially throw their hat in the ring.“I would imagine we're going to have some candidates announcing their runs either at the end of this year, so the end of December, or in the first two months of 2019,” says Brown.Brown published a book on presidential nominations and elections called “Jockeying for the American Presidency: The Political Opportunism of Aspirants.”Brown says Democrats can expect a crowded field, just like the Republicans had in 2016.While no one has officially announced a party candidate, a list of potential candidates has been building for months.“We're going to have a lot of different Democrats from a lot of different regions, trying to make the argument they're really the one to lead the party and bring the White House back to the Democrats.”While it's rare that an incumbent president loses a re-election campaign, Brown says President Trump is vulnerable.“It’s evident after the 2018 elections that the Republican party's base is shrinking,” she says. “They are not appealing to as many people as they used to. There's now a 20-point split among women in terms of who and what party they favor.” 1583
