People concerned about getting Covid can still protect themselves by properly wearing masks, like an N95 or KN95, even if nobody else around is, Dr. Scott Gottlieb told CNBC on Wednesday.

Gottlieb's comments come two days after a federal judge in Florida nullified the Biden administration's Covid mask mandate for public transportation, including airlines. Many mask rules for other settings have already been relaxed.
