As health experts warn about rising coronavirus cases from spread at indoor gatherings, a new website backed by recent research is trying to help people understand just how many people in what size space is risky for infection. Which could come in handy as some people consider small holiday gatherings.It’s more risky to be in a small room compared to a large gym. If people are calm and quiet, it is safer than singing or exercising no matter how distant they are.Given these types of scenarios, and the “rapidly advancing science” of how COVID-19 droplets behave, scientists at the Massachusetts Institute of Technology created the COVID-19 Indoor Safety Guideline application.Here’s an example:An average suburban house that is 2,000 square feet, with 25 people inside wearing cotton masks and talking in a whisper, can reduce their risk of transmission by only staying inside for 4 hours.If those same 25 people, in the same house, are not wearing a mask and are talking normally, the length of time to reduce transmission drops to just 50 minutes.And if those 25 people, in the same house, are singing along to Christmas music, without masks on, that time to safely reduce COVID-19 transmission indoors drops even further to just 8 minutes.If the size of the gathering is only 5 people, and there is still singing, no mask wearing, and it’s still a 2,000 square foot house, it becomes unsafe after just 27 minutes.The MIT website offers users the ability to select room size, number of people and length of time, then using previous research and scientific knowledge of airborne viruses, it predicts the risk of the indoor event. Users can change elements of the situation, like room size, mask wearing, ventilation, etc.Click here to visit the Indoor Safety Guideline website.In a restaurant, to reduce transmission, 50 people without masks and talking normally should stay for only two hours. If the restaurant has 100 people, to reduce transmission risk, they should only remain inside for 64 minutes.The researchers note current general social distancing guidelines (remain 6 feet apart) suggest 138 people would reduce their risk in the same size of space for an indefinite amount of time.Another example, a Boeing 737, the researchers’ model predicts 100 people can be onboard a 737 wearing masks and still reduce their risk of transmission by staying onboard less than 6 hours.The CDC updated their guidance about COVID-19 this fall, acknowledging ongoing research that shows coronavirus droplets “can remain suspended for many minutes to hours (in the air) and travel far from the source on air currents.”The Centers for Disease Control and Prevention also says coronavirus droplets can remain even when an infected person has left the room and can travel farther than six feet. 2800

America's largest group of child doctors updated its guidance on cloth face coverings for kids in sports to cover competition on Friday and now recommend youth athletes wear cloth face masks during games.The American Academy of Pediatrics' previous recommendation suggested they wear masks on the sidelines, in between drills, or when entering or leaving the field.In addition to wearing masks during games, the AAP also suggests that practices are kept small and teams do not mix with other teams or coaches.The AAP added that face coverings can be removed when participating in swimming, or where they could become a choking hazard or impair vision like in cheerleading, gymnastics, or wrestling. 706

Americans aren’t exercising like they used to.“I’ve definitely been walking a whole lot less since the coronavirus hit,” Nathan Martin said.With social distancing orders put into place, the pandemic has many people spending more time at home.“I was a little bit less active and more Netflix,” Hannah Hockensmith said.Now, a new study is showing this drop in physical activity is increasing health concerns across the globe.“COVID-19 is a worldwide phenomenon unlike anything else we’ve seen in generations,” said Dr. Geoff Tison, a cardiologist at the University of California, San Francisco.Tison recently finished a new study using smartphone apps to track the step counts from almost half a million people in countries worldwide.The data was collected from mid-January to early June and the findings show the world is walking a lot less.“Within the first month of the pandemic, declaration activity decreased by about 27%,” he said.Tison says this lack of physical activity could damage people’s health, especially in older adults.“With decreased activity, increased sitting on the couch, just not being as active is muscle mass can start to decrease as can bone density,” he said.In America, the study shows the biggest drop in step counts happened in New York City while Dallas had the smallest decrease.“The changes in activity seem to reflect adherence to social distancing at least to a degree,” Tison said.To increase exercise indoors, Tison says is all about thinking outside the box.“You can do similar exercises, work similar muscles with things around the house,” he said. “Use a gallon of milk instead of a dumbbell.”To exercise outdoors, however, Tison believes changes need to happen at the city and state levels.“Policy makers, governments need to be creative understanding that people are humans and want to be active and want do things,” he said. “But to enable them to do that safely.” 1913
