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 stock market sank deeper into the red following sluggish economic reports on Monday and bad news from a couple of blue-chip giants.The Dow fell 600 points by late afternoon, or 2.6%. The S&P 500 lost 2.6% and retreated to its lowest level of the year. And the Nasdaq joined the Dow & S&P 500 in negative territory for 2018. All three indexes have plunged about 7% so far this December.The Dow closed down 507 points for the day.And the Russell 2000 index of small-cap stocks tumbled into a bear market, marking a 20% decline from the record highs notched in late August.A weaker reading from the New York Federal Reserve about manufacturing in the Empire State and a drop in confidence from the nation's homebuilders weighed on the markets."Investors are zeroing in on this idea of slower growth for 2019," said Michael Arone, chief investment strategist at State Street Global Advisors. "More people are worried about a recession in late 2019 or 2020."The political noise in Washington isn't helping either. President Trump, in a tweet Monday morning, repeated his criticism of the Federal Reserve for its recent rate hikes. The Fed meets Wednesday and is widely expected to raise rates again.But Trump tweeted that "it is incredible that with a very strong dollar and virtually no inflation, the outside world blowing up around us, Paris is burning and China way down, the Fed is even considering yet another interest rate hike. Take the Victory!"The Fed is supposed to be politically independent. Any evidence that it might be swayed by attacks from Trump could unnerve the markets."If the Fed doesn't raise rates it will look like it's succumbing to the bullying of Trump's tweets," Arone said.But Nancy Perez, managing director at Boston Private, said the Fed is likely to slow down its pace of rate hikes in 2019 simply because the economy is slowing, not because of pressure from Trump.Perez added that the recent market turmoil is justified because investors are readjusting to this fact."We have been getting a bump in profit margins due to lower taxes but the earnings growth itself is not sustainable," Perez said. "Projections will come down and volatility will continue." 2247

The Supreme Court said on Monday that it will stay out of the dispute concerning the Deferred Action for Childhood Arrivals program for now, meaning the Trump administration may not be able to end the program March 5 as planned.The move will also lessen pressure on Congress to act on a permanent solution for DACA and its roughly 700,000 participants -- undocumented immigrants who came to the US as children.Lawmakers had often cited the March 5 deadline as their own deadline for action. But the Senate failed to advance any bill during a debate earlier this month, and no bipartisan measure has emerged since.  627

The University of Florida's football team is suspending activities following an “increase” in COVID-19 cases among members of the team, the university announced on Tuesday.The announcement comes just days after head coach Dan Mullen called on the university to open Ben Hill Griffin Stadium to a full capacity of 90,000 for the rest of the season. The state of Florida currently does not have a capacity restriction on stadiums."I know our governor passed that rule, so certainly, hopefully the university administration decides to let us pack the Swamp against LSU … 100 percent, because that crowd was a major factor in the game,” Mullen said following last Saturday’s 41-38 loss against Texas A&M. “So, I certainly hope our university administration follows the governor. The governor has passed a rule that we're allowed to pack the Swamp and have 90,000 in the Swamp to give us the home-field advantage Texas A&M had."The stadium is currently open at 20% capacity.Athletics director Scott Stricklin said the suspension was out of an “abundance of caution.”Sports Illustrated reported that the Gators had five new coronavirus cases identified on Tuesday.As of Tuesday afternoon, this Saturday’s game between Florida and LSU is still on as scheduled. 1269
