Dr. Anthony Fauci, the nation's leading infectious disease expert, told "CBS Evening News" anchor and managing editor Norah O'Donnell that the United States needs to redouble its efforts to contain the coronavirus as we enter the fall and winter months…. He noted that coronavirus cases are surging in 37 states, a concerning rise affecting over three-quarters of the country.…. The surge could be made worse as families across the country travel and gather for the holiday season. Fauci said some beloved traditions, like big Thanksgiving gatherings, may need to be avoided this year to keep people safe…."You may have to bite the bullet and sacrifice that social gathering, unless you're pretty certain that the people that you're dealing with are not infected."
