NBC medical correspondent Dr. John Torres tells TODAY that a coronavirus saliva test developed by researchers at Yale could be “a bit of a game changer” due to such factors as wide availability and shorter turnaround time for results, but warns that cases could surge once cold weather arrives. NBC investigative and consumer correspondent Vicky Nguyen advises parents to talk to their schools about reopening plans, get flu shots for the family, and practice “mask endurance” with children.
