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

The CDC reports that the number of flu cases is low right now, and it could be because of safety precautions to slow the spread of the coronavirus, including wearing masks and remaining distant from people in public. Also, high levels of flu vaccinations.The Centers for Disease Control and Prevention tracks flu vaccine distribution and shows, so far for the 2020-2021 season, just under 190 million flu vaccines have been distributed. This compares to about 174 million distributed during the whole 2019-2020 season.According to the CDC’s weekly “flu view” update, “seasonal influenza activity in the United States remains lower than usual for this time of year.”“Overall flu activity is low, and lower than we usually see at this time of year,” Dr. Daniel B. Jernigan, director of the influenza division of the Centers for Disease Control and Prevention, told the New York Times. “I don’t think we can definitively say there will be no twindemic; I’ve been working with flu for a long time, and I’ve been burned. But flu is atypically low.”However, they caution that flu activity may increase in the coming months. Flu season typically peaks at the beginning of the year, depending on the region.The CDC’s map showing state-by-state flu activity shows the majority of the country with “minimal” rates of flu activity, with Oklahoma at a low “moderate” level. A comparison to the 2019-2020 season showed two states were in the moderate level at this time.“The unprecedented demand we’ve seen for flu shots this season, along with safety precautions everyone is taking to limit the spread of COVID-19, such as social distancing, wearing facemasks and frequently washing their hands, may be contributing to lower flu activity this season,” Dr. Kevin Ban, the chief medical officer at Walgreens, said in a written statement.Related: Is it the flu or coronavirus? Walgreens is reporting fewer sales of antiviral medications for flu so far this season compared to 2019. The health and wellness company has a flu tracker each season that tracks regional activity.Health experts remind everyone it is not too late to get the flu vaccine and be protected for the 2020-2021 flu season. 2186

The brother of an unarmed black man killed by police interrupted a Sacramento City Council meeting on Tuesday as chants of the victim's name filled the chambers, illustrating how the fatal shooting has sparked emotions in this California city."Stephon Clark. Stephon Clark," Stevante Clark and others chanted in the first meeting since the fatal shooting on March 18."Louder. Louder," said Stevante Clark, who hopped on the dais and yelled an expletive at Mayor Darrell Steinberg.Standing in front of the council chambers with others, Stevante Clark said: "The mayor and the city of Sacramento has failed all of you," citing high rent, gang violence and poverty in the city.The outburst forced council members to take a brief recess. 746

The doors to Interior Secretary Ryan Zinke's office are getting a nearly 9,000 upgrade.The Interior Department confirmed the project Thursday, saying it is both necessary to replace old doors that are in "disrepair" and attributing the high cost to the historical nature of the building.News of the 8,670 contract comes as several agencies are facing scrutiny over excessive spending. Last month, Housing and Urban Development Secretary Ben Carson withdrew an order for pricey dining room furniture, including a ,000 table. Zinke is also under fire for questionable travel habits.Zinke was unaware of the expense for the doors, Interior spokeswoman Heather Swift said, saying the project was driven by "career facilities and security officials" as part of a decade-long modernization of the 1930s building."The secretary was not aware of this contract but agrees that this is a lot of money for demo, install, materials, and labor," Swift said in a statement. "Between regulations that require historic preservation and outdated government procurement rules, the costs for everything from pencils to printing to doors is astronomical. This is a perfect example of why the secretary believes we need to reform procurement processes."The new doors will be made of fiberglass. The previous sets of doors have been damaged for years, according to an Interior official, to the point where wind and water come into the office during inclement weather, which in turn damaged the historic hardwood floors. Damage has caused bottom panels to fall out and be "replaced with cardboard and duct tape," the official said.The Associated Press previously reported on the door contract Thursday."What a waste. Just think how many dining sets you could have bought or private jets you could have chartered with that money," Rep. Adam Schiff, D-California, joked on Twitter. 1898

The FBI has taken custody of multiple suspicious packages sent to military locations in the Washington, DC area, a law enforcement official said Monday. The official said two of the packages were sent to Fort Belvoir and Fort McNair.At least one package, sent to the National Defense University at Fort McNair in Washington, DC, contained explosive material and was ultimately rendered safe. That package arrived at 8:30 a.m. ET and the building was evacuated immediately, according to Army spokesman Michael L. Howard."At 12:10 p.m., 52nd Army Explosive Ordnance Disposal from Fort Belvoir, VA, confirmed the package tested positive for black powder and residue," Howard said in a statement. "The X-ray conducted indicates suspected GPS and an expedient fuse were attached. The package was rendered safe. No injuries are reported."Scanning machines at the facilities detected the suspicious materials upon receipt and the packages are being examined at the FBI lab in Quantico, Virginia, the law enforcement official said.The National Defense University at Fort McNair was cleared for re-entry after K-9 sweep and personnel returned to the building by 1:15 pm ET.Another Army spokesman confirmed a suspicious package incident at Fort Belvoir and said that package has been rendered safe. 1296
