WASHINGTON, D.C. – Joe Biden painted a very different picture of the COVID-19 pandemic than President Donald Trump during his first briefing as the nation's president-elect on Monday. "We are still facing a very dark winter," Biden said after a briefing with his advisers in Delaware. Biden announced a new COVID-19 advisory board. The group will be co-chaired by Dr. David Kessler, a former Food and Drug Administration commissioner; Dr. Vivek Murthy, a former surgeon general of the United States; and Dr. Marcella Nunez-Smith, a public health professor at Yale University. "Please wear a mask," Biden implored those watching. WHAT WOULD CHANGE UNDER BIDEN When President-elect Biden takes office, more than just "presidential tone" will change. "They are going to allow the evidence to be back in the driver seat," said Dr. Jon Andrus, an adjunct professor of global health at The George Washington University. Some of the potential changes include: a national mask mandate, more guidance to governors and mayors, increased reliance on international health groups, and more testing and contact tracing. "Lessons learned from many countries, such as those in southeast Asia, show aggressive testing and contracting tracing works," Andrus said. Biden's statement to the media came on the same day Pfizer released promising news about a potential vaccine, saying it 90% effective in some of their trials. 1413

We're seeing more antiviral products popping up that claim to protect you against COVID-19.Pakistan-based denim company Artistic Denim Mills is making pants and masks using antiviral technology it says tested nearly 100% effective in 30 minutes against coronavirus.Denim brand Diesel is planning to add different antiviral technology to its jeans next year that it says can disable nearly all viral activity within two hours of contact.Other companies are selling antibacterial gloves that claim to destroy bacteria and micro-organisms.These are big claims, but are they true?“The people that we shouldn't trust, honestly, are the people that stand to gain financially from this,” said Dr. Mark Shrime, a professor at Harvard Medical School. “Not because they're necessarily nefarious, but they have an ulterior motive to market these products to our uncertainty and to our fear without necessarily doing the due diligence that we might want them to do in less uncertain times.”Shrime says we don't know a lot about how COVID-19 spreads on surfaces. There are no confirmed cases of surface transmission so far.He questions if these products actually do anything for you.“For sure, they haven't been rigorously tested,” said Shrime. “You will see things often that they have been scientifically formulated or other words like that, that make it sound like this is super cool, but they haven't necessarily been rigorously tested to see if they actually prevent the virus.”He points to antibacterial soaps that were all the rage for a while. The Food and Drug Administration later said they're no more effective than regular soap and water.He says instead of paying extra for what companies say is extra protection, focus on what we know works – wash your hands and wear a mask. 1783

WASHINGTON (AP) — President Donald Trump wore a mask during a visit to a military hospital on Saturday.It's the first time the president has been seen in public with the type of facial covering recommended by health officials as a precaution against spreading or becoming infected by the novel coronavirus.Trump flew by helicopter to Walter Reed National Military Medical Center in suburban Washington to meet wounded service members and health care providers caring for COVID-19 patients.As he left the White House, he told reporters: “When you’re in a hospital, especially ... I think it’s expected to wear a mask.”Back in May, a photo surfaced on social media of President Trump wearing a mask during a tour of a Ford plant in Michigan. President Trump, however, did not wear a mask during the public part of the tour.WFTS' Jonathan Lemire and the Associated Press first reported this story. 902

  

WASHINGTON (AP) — Vice President Mike Pence has called off campaign events in Florida and Arizona for this coming week as the states experience a surge in new coronavirus cases. The White House says Pence will still travel to those states to meet with their governors and health teams. Florida and Arizona have set records for new confirmed infections in recent days. Pence is traveling to Dallas on Sunday to attend a “Celebrate Freedom Rally” at First Baptist Church Dallas before meeting with Texas Gov. Greg Abbott. But political events in Arizona on Tuesday and Florida on Thursday have been pushed off. 616

  

WASHINGTON (AP) — The two most senior officials in the U.S. Department of Homeland Security were improperly appointed to the posts under federal law by the Trump administration, a nonpartisan congressional watchdog said Friday.The Government Accountability Office says acting DHS Secretary Chad Wolf and acting deputy Ken Cuccinelli are ineligible to run the agency under the Vacancy Reform Act. The GAO says it has asked the DHS inspector general to review their status and decide whether the apparent violation of the Vacancy Reform Act has any effect on actions they took while holding the post. The report does not carry the force of law, though it could be a factor in lawsuits challenging administration policies or influence members of Congress.For its part, DHS rejected the finding.“We wholeheartedly disagree with the GAO’s baseless report and plan to issue a formal response to this shortly,” the agency said in a written response to The Associated Press.Democrats in Congress called on Wolf to resign. 1021
