The U.S. Food and Drug Administration updated its guidance on face coverings on Tuesday, adding information about wearing expired surgical masks.According to the FDA, face and surgical masks may still offer protection even if they've passed their designated shelf life or expiration date."If there is no date available on the face mask label or packaging, facilities should contact the manufacturer. The user should inspect all masks before use and, if there are concerns such as degraded materials (such as elastic) or visible tears," the agency recommends that you should discard the product.However, when it comes to re-using surgical disposal masks, the CDC recommends discarding them after one use.You can clean reusable masks, the CDC says, and recommends washing them after each use. For N95s, which the CDC considers a one-time-use product, but can be re-worn if cleaned with an approved decontamination method. 927
The US Forest Service hopes families will want to end 2020 with a live tree, preferably one cut from a national forest.Cutting down a Christmas tree is a tradition for many, and a healthy tradition for the forests as smaller trees get thinned out.“By cutting your own tree, you take an active part in managing your national forests,” according to the US Forest Service webpage.Tree hunters should look for an area of tightly-knit, dense trees and pick one from there. This will in turn give the surrounding trees more space to grow, Hillary Santanez, recreation event coordinator with the White River National Forest, explained to KMGH.Thinning the forests in this fashion reduces competition for resources and nutrients so the other trees can grow stronger and healthier, Santanez said. It also helps the trees handle stressful environmental situations, such as drought. In addition, thinning dense forests can help with wildfire mitigation.Families who have a fourth or fifth grader can get a free permit from the Every Kid Outdoors initiative through the US Forest Service. Otherwise, permits to cut down a tree in a national forest run to depending on the park. Permits are required. All permit sales are online for 2020, along with maps, how to select a tree, guidance for cutting it down and safety reminders. Like, dressing for the cold, possibly dark and snowy forest conditions. The different parks have different rules about where a Christmas tree can be cut down from, usually it has to be about 200 feet from roads and campgrounds."You want to make sure that you're not trespassing on private property, so going onto our website and downloading a map is essential so that you can make sure that you're staying on forest land because a lot of the forest land, especially in the Front Range area, is really adjacent to private property, and you have to make sure that you're following the law while you're up there," Pike and San Isabel National Forests and Cimarron and Comanche National Grasslands Public Affairs Officer Crystal Young told KOAA News.There are height and trunk size requirements as well to make sure tree hunters are taking the smaller trees to help thin out forests.

The U.S. has now seen two straight weeks in which at least 100,000 people are confirmed to have contracted COVID-19 each day.On Monday, the U.S. reported 166,000 new cases of the virus, marking the 14th consecutive day with 100,000 or more new cases of the virus, according to a database kept by Johns Hopkins University.The last day new cases totaled less than 100,000 was on Nov. 2. Since then, about 1.9 million Americans have contracted the virus, the rolling 7-day average of hospitalizations across the country has increased from 50,000 to 65,000 and daily deaths on a rolling 7-day average have ticked up from 824 a day to 1,114 a day.That 14-day time span has also seen seven days in which record numbers of new cases were reported. The current record was set on Friday when 177,000 people in the U.S. were confirmed to have contracted COVID-19.The current spike in caseloads has led hospitals across the country to become inundated with patients, overwhelming resources. The COVID Tracking Project reports that most of those hospitalizations are occurring in the Midwest, where rural hospitals in places like Iowa and South Dakota are running short on bed space.The current standard was predicted in June by Dr. Anthony Fauci, the nation's highest-ranking infectious disease expert. During a Senate hearing, Fauci stunned lawmakers by predicting that the U.S. could reach a point where 100,000 people were being infected each day if "disturbing trends" continued.Fauci's comments in June came during a summer spike in cases which saw infection rates top out at about 77,000 new cases each day.The current spike in cases comes as drugmakers like Pfizer and Moderna have reported encouraging results in vaccine trial results. While both vaccine candidates are on track for Emergency Use Authorization by the end of 2020, the drug likely won't be widely available to the general public for several months — Fauci has predicted that a vaccine will be widely available in the U.S. by April. 2002
