The United States confirmed nearly 45,000 new cases of coronavirus on Wednesday, as the official U.S. death toll rapidly approaches 180,000. On Wednesday, the White House defended a decision by the Centers for Disease Control and Prevention to recommend against coronavirus testing for people who lack symptoms of COVID-19 — even if they’ve been exposed to an infected person. The CDC also quietly dropped its recommendation that people quarantine for 14 days after traveling from an area with a high rate of infection. Public health experts say the moves will undermine efforts to control the spread of the disease. The New York Times cited two federal health officials who said the changes were ordered by higher-ups at the Department of Health and Human Services and the White House. The decision was reportedly made at an August 20 meeting of the White House Coronavirus Task Force, while top public health expert Dr. Anthony Fauci was not present because he was undergoing surgery. The changes were backed by the task force’s newest member, Dr. Scott Atlas — a Fox News contributor and radiologist with no expertise in infectious diseases.
