The CDC is now recommending “universal mask use” both indoors and outdoors whenever someone is not at their own home. This is the first time the agency has included indoor spaces in their recommendations for universal mask wearing.It comes as coronavirus cases in the U.S. continue to surge past 14 million positive cases and deaths climb above 277,000, with many states only beginning to see a potential second spike from Thanksgiving celebrations.In the CDC’s weekly report, they said with more time spent indoors with the colder weather, the ongoing holiday season and silent spread of the disease with about 50 percent of transmission happening from asymptomatic people, “the United States has entered a phase of high-level transmission where a multipronged approach to implementing all evidence-based public health strategies at both the individual and community levels is essential.”These include universal mask use, physical distancing, avoiding nonessential indoor spaces, increased testing, prompt quarantine, enhanced ventilation, and widespread vaccination coverage. The agency stresses “no single strategy can control the pandemic,” and all of these recommendations will be needed to break transmission chains.The CDC warns that indoor spaces and crowded outdoor spaces, especially where distancing is not maintained or consistent use of face masks is not possible, i.e. like when eating or drinking, “have been identified as particularly high-risk scenarios.”“Compelling evidence now supports the benefits of cloth face masks for both source control (to protect others) and, to a lesser extent, protection of the wearer,” the CDC guidelines now read. “Face mask use is most important in indoor spaces and outdoors when physical distance of ≥6 feet cannot be maintained. Within households, face masks should be used when a member of the household is infected or has had recent potential COVID-19 exposure.”Any indoor spaces should also have good ventilation, the CDC says. "For indoor settings, increased room air ventilation can decrease the concentration of small droplets and particles carrying infectious virus suspended in the air and, thereby, presumably decrease the risk for transmission."The World Health Organization recently updated their guidelines that everyone 12 and older should wear a mask outside, inside and even inside people’s own homes if they are poorly ventilated. They recommended that children ages 6-to-11 should wear a mask based on a “risk-based approach.”Earlier this week, the CDC said they recommend against traveling this holiday season to slow the spread of the coronavirus. They made a similar plea before Thanksgiving, however the TSA reported record-high airport screenings since the pandemic started. 2758

The chemotherapy dripped through a catheter in his chest. Cancer patient Robert Goodman had burned through his paid sick days while undergoing surgery and chemotherapy for colon cancer.The Florida public school teacher figured he needed at least 20 additional sick days to deal with more chemotherapy, days he just didn't have. So on July 23, right there in a room at Tomsich Health and Medical Center of Palm Beach County, Goodman took a selfie, posted it on Facebook and appealed for help.Within four days he had enough sick days to cover an entire semester."I couldn't believe it happened so fast," Goodman, 56, told CNN.Teachers, staff members, administrators and even lunchroom workers who pay into the Florida retirement system transferred 75 sick days to Goodman."Educators all over the country were reaching out to me to donate their sick days, even professors over at Florida Atlantic University," he said. "I felt guilty because I knew there were people who had it much worse than me." 1003

The Centers for Disease Control and Prevention issued new guidance that recent studies have indicated that cloth masks offer more protection against the coronavirus than previously thought.Previous guidance suggested that masks were best used for preventing the spread of the virus. The CDC now believes that masks are effective for both stopping the spread and reception of the virus. The CDC said on Tuesday that multi-layer cloth masks can both block up to 50 to 70% of fine droplets and particles and limit the forward spread of those that are not captured. Overall, cloth masks offer up to 80% blockage in human experiments. The CDC’s analysis found that cloth masks offer comparable protection as surgical masks.“Studies demonstrate that cloth mask materials can also reduce wearers’ exposure to infectious droplets through filtration, including filtration of fine droplets and particles less than 10 microns,” the CDC’s guidance said. “The relative filtration effectiveness of various masks has varied widely across studies, in large part due to variation in experimental design and particle sizes analyzed. Multiple layers of cloth with higher thread counts have demonstrated superior performance compared to single layers of cloth with lower thread counts, in some cases filtering nearly 50% of fine particles less than 1 micron.”The guidance says that mandatory mask wearing can help prevent the need to implement economic shutdowns.“Adopting universal masking policies can help avert future lockdowns, especially if combined with other non-pharmaceutical interventions such as social distancing, hand hygiene, and adequate ventilation,” the CDC said.In an interview with Andrea Mitchell of MSNBC, Dr. Anthony Fauci said that wearing masks is “two-way street.”"Recent data has now shown that as a matter of fact, there's also the added benefit to protect you from droplets and virus that's coming your way," Fauci said Tuesday on MSNBC."“You protect others," he added. "Their masks protect you. And your mask also protects you."In a separate interview on Tuesday, Fauci said that shut downs can be avoided.“We are not talking about shutting down,” Fauci told CNN’s Jake Tapper. “There is always that misunderstanding when we talk about public health measures. We are not talking about shutting down. We are talking about the four or five things I talk about all the time, wearing mask universally, keeping a distance, avoiding congregate settings indoors over outdoors and washing your hands.”Editor's note: A previous version of this story said "masks were best used for spreading the virus" when it should have said "masks were best used for preventing the spread of the virus." That has since been corrected. 2729
