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 Federal Bureau of Investigation has asked the public’s help in identifying members of a female gang who have been spotted in Middle Tennessee.  The FBI said Felony Lane Gang members use rental cars with tinted windows to watch you and your car in parking lots at gyms, daycares or anywhere someone might leave a purse in a car.They have been spotted in Nashville, Mt. Juliet, Gallatin and several other towns around the Metro area.When they see an opportunity, they'll swipe IDs, credit cards and checkbooks. Then, they hand all of that over to prostitutes and drug users they recruit to impersonate victims.Those women take stolen checks and IDs to multiple banks to withdraw large amounts of money -- all before the victims have a chance to close their accounts.According to authorities, they use the farthest window from the teller in bank drive-thru lanes. This drive-thru lane is commonly known as the "felony lane," which is what inspired their nickname.Investigators said they’re known to use wigs and other disguises to impersonate their victims at banks. If you have information call the FBI office in Memphis at 615-232-7500.  1158

The Centers for Disease Control and Prevention's own medical advisers are criticizing the federal health agency for being slow to respond to a polio-like disease that's struck hundreds of children over the past six years."Frustrated and disappointed -- I think that's exactly how most of us feel," said Dr. Keith Van Haren, one of the CDC advisers on AFM and an assistant professor of neurology at the Stanford University School of Medicine.Van Haren and other doctors who care for these children say the agency has been slow to gather data and to guide pediatricians and emergency room physicians on how to diagnose and treat the children struck with the disease, acute flaccid myelitis."This is the CDC's job. This is what they're supposed to do well. And it's a source of frustration to many of us that they're apparently not doing these things," said Dr. Kenneth Tyler, a professor and chair of the department of neurology at the University of Colorado School of Medicine and another adviser to the CDC on AFM. 1022
