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 collective mourning of a community shaken by a brazen act of violence in a synagogue will continue Tuesday as funerals are held for three of the victims of what the Anti-Defamation League said was the deadliest attack against Jews in US history.On Monday night, blue light washed over the night sky as buildings across Pittsburgh were illuminated in tribute to the 11 worshippers killed Saturday when a gunman stormed the Tree of Life synagogue there.The close-knit community of Squirrel Hill, where the shootings took place, will first bid farewell to brothers Cecil and David Rosenthal and Dr. Jerry Rabinowitz, according to CNN affiliate WTAE.The funerals coincide with a visit from President Donald Trump, who will travel to Pittsburgh Tuesday despite a request from the city's mayor to hold off on visiting.  830

The Department of Defense says the military parade originally scheduled for Veterans Day will be postponed."The Department of Defense and White House have been planning a parade to honor America's military veterans and commemorate the centennial of World War I," Defense Department spokesman Col. Rob Manning said in a statement Thursday. "We originally targeted November 10, 2018 for this event but have now agreed to explore opportunities in 2019."The parade was scheduled for the day before the 100th anniversary of the armistice that ended the First World War. French President Emmanuel Macron is holding a gathering of world leaders in Paris on November 11 to celebrate the anniversaryCNN previously reported that the parade would focus on celebrating veterans and involve US troops in period uniforms as well as US military aircraft but no heavy vehicles like tanks in order to prevent damage to infrastructure.The price tag of the proposed parade has sparked criticism. On Thursday, the American Legion reacted to reports that the parade could cost tens of millions more than originally expected by saying the money would be better spent in other ways."The American Legion appreciates that our President wants to show in a dramatic fashion our nation's support for our troops," American Legion national commander Denise Rohan said in a statement. "However, until such time as we can celebrate victory in the War on Terrorism and bring our military home, we think the parade money would be better spent fully funding the Department of Veteran Affairs and giving our troops and their families the best care possible."Trump said in February that a military parade in Washington would be "great for the spirit of the country," but that it would need to come at a "reasonable cost." The President said he was inspired by the Bastille Day parade in France, which he described as "quite something" after attending in 2017.The Department of Defense says the military parade originally scheduled for Veterans Day will be postponed. 2062
