As mandatory face coverings become more and more common, keep in mind, some are better at protecting from viruses than others.When issuing their face covering guidelines, San Francisco specifically called out masks with one-way valves designed for “easier breathing”, warning that they allow for droplets to get out of the mask and potentially endanger others nearby. These valves are usually about the size of a coin on the side of the mask.The CDC, and many other health departments and officials, urge wearing a mask to prevent the spread of the coronavirus because it can be spread through respiratory droplets. Those droplets are produced into the air when an infected person coughs, sneezes, talks, sings, chants, shouts, etc. They can then land on other people nearby or be inhaled by others.The CDC recommends people wear a cloth face covering in public settings, to reduce the transmission of droplets into the air.“There are no high quality studies regarding the use of masks with additional types of various filters placed in them or with ‘breathing valves.’ While widely marketed with various claims, these have not been studied at all and it is unclear if they help or hurt the overall filtration efficacy against microorganisms,” read a statement from Marc Sala, M.D., Assistant Professor of medicine in the Division of Pulmonary and Critical Care at Northwestern University’s Feinberg School of Medicine.People are being asked to leave N95 masks (without a valve) and surgical masks available for medical staff and essential personnel who are coming into daily contact with many infected patients.An N95 mask with an exhalation valve is not recommended because unfiltered air is sent through the valve and into the air, potentially carrying coronavirus droplets. “The presence of an exhalation valve reduces exhalation resistance, which makes it easier to breathe (exhale). Some users feel that a respirator with an exhalation valve keeps the face cooler and reduces moisture build up inside the facepiece. However, respirators with exhalation valves should not be used in situations where a sterile field must be maintained…” according to the CDC’s website.Dr. Sala said testing has shown things like multiple layers of cotton fabric is better than a single layer, material of a higher thread count is more effective, and overall, “these studies emphasized the notion that if a mask doesn’t have a good fit (has gaps) its effectiveness is dramatically reduced.” Dr. Sala said even if the cloth mask is not ideal, it can still play a major role in preventing illness as more masks are worn by the population as a whole.Bottom line, choose a fabric face covering that fits and is comfortable around your ears or head, and keep it on while in public, especially when social distancing is not possible, to protect you and the people around you. 2864

Another reason to wash those hands, Thursday is Global Handwashing Day.October 15 has been designated as a day to remember that “soap and water is one of the best steps we can take to avoid getting sick and spreading germs to others,” according to the Centers for Disease Control and Prevention.Global Handwashing Day was established in 2008 by the Global Handwashing Partnership, an international organization dedicated to awareness about the health and economic benefits of handwashing hygiene and making clean water and soap available to all.This year’s Global Handwashing Day is also a reminder that proper handwashing with soap is a recognized way to stop the spread of the coronavirus.This year’s theme is “hand hygiene for all” and “calls for institutions and individuals to improve hand hygiene efforts in the COVID-19 response that can outlast the pandemic and ensure continued access to clean water and soap,” the CDC says.The CDC estimates that the number of colds and respiratory illnesses in a community could be reduced between 16-21 percent with handwashing education.The CDC has some recommendations for proper handwashing:There are 5 easy steps to washing hands: wet, lather, scrub, rinse and dry.Wash for 20 seconds with soap and water.Make it part of the routine:Before you eatAfter using the restroomComing inside from spending time outside or in publicAdults can be a good role model and wash hands often.With younger children, make it a family activity and wash hands together.Choose a song or music verse to sing while washing. Need ideas? Try this, this or this (including hits from Prince, Lizzo, Toto and Beyonce). Yes, even older kids can sing while washing their hands. 1705

She said the accident and necropsy report will be reviewed "to learn what, if anything, could have been to prevent the accident."Benson said Santa Anita will work with the California Horse Racing Board to investigate the accident.Trained by Phil D'Amato, Satchel Paige was winless in six career starts, with one second and one third-place finish. He had career earnings of ,002.He was bred and owned by retired luxury car dealer Nick Alexander, chairman of the Thoroughbred Owners of California, which represents the collective interests of owners in the state and works to preserve the sport's long-term viability.Santa Anita is set to host the Breeders' Cup world championships for a record 10th time on Nov. 1-2. 1392

As a third-grade elementary school teacher, Reed Clapp never imagined he would be finishing the school year sitting inside the living room of his home. But the COVID-19 outbreak had other plans for this teacher and so many others across the country.Undeterred by a nationwide pandemic, Clapp was determined to finish out this school year the same as any other: with a play that he and fellow teacher, Karen Snyder, have produced for the last five years.“This is one of the most challenging things I’ve ever taken on,” he said, sitting inside the living room of his home in Nashville, Tennessee.The name of the show Clapp and his class would perform in years past was called, “Grammarella,” a satirical production of Cinderella, where every student plays a part of speech. The character Interrogative, for example, can only speak in questions.On the last day of every school year, Clapp’s students would perform the play in front of their classmates at Madison Creek Elementary School in Hendersonville, Tennessee. It’s become such a hit over the years that there’s typically not an empty seat in the school’s library on opening afternoon, which is also closing night. There’s only one showing.But how could Clapp, harness that same kind of magic without his kids physically at school?After a few weeks of thinking, he decided the answer to that question was right in front of him: he’d move the play to Zoom, a virtual video platform.“Instead of saying, ‘we won’t have a play this year,’ we decided to say, ‘how can we do something that is original and something these kids are proud of?” he said.As summer vacation loomed, Clapp and his third-graders began to double down on their work. This energetic 33-year-old teacher with a thick southern drawl knew the script for “Grammarella” would have to be thrown out. So, he started from scratch and came up with an original screenplay, “Zoomarella.”Students auditioned for lead roles on Zoom, and they even practiced social distancing by picking up costumes that Mr. Clapp and Ms. Snyder had left outside on their front porches.Over the course of a few weeks, the play started coming together. Eight and 9-year-old students learned how to be punctual for rehearsal times, that instead of being held in the classroom, they were being held on Zoom. While Clapp’s original intent was to help students learn grammar, he quickly released that “Zoomarella” was teaching his students more important life skills.“Yes, they’re 8 years old, but when we say, ‘we need some light behind you,’ what we’re really saying is, ‘what can you do to put a light behind you?’” he explained.“These kids have become set designers, light designers, camera operators. It’s amazing,” he added.And for students facing isolation at home, rehearsals offered a sense of a vehicle for creativity that might have otherwise been lost when the school closed.“The stuff that has been the hardest is getting facial expressions and acting with your body. You have to use your body and facial expressions and not just when it’s your turn to talk,” explained 9-year-old Autumn Fair.Weeks of practicing finally paid off for Fair and her classmates, as “Zoomarella” was performed without a hitch during the last week of school. And even though the kids might not have been able to hear the applause through their Zoom meeting, Clapp says he couldn’t have been prouder of his kids.“I hope they take away a moment in time that’s been captured in a unique way. Instead of looking back on all this through news stories, they’ll have this play to look back on,” the proud teacher said.Watch “Zoomarella” below: 3619
