CNN/As spring break travel picks up and states increasingly drop Covid-19 restrictions, Dr. Francis Collins, the National Institutes of Health director, is pleading with people to keep using masks regardless of prevailing rules.
“If there ever was a time to put on the mask, this is it,” Collins told MSNBC’s Ali Velshi on Saturday.
Collins’ comments to MSNBC come as encouraging signs — falling case counts, rising vaccinations — converge with public health experts’ concerns that more-transmissible variants are gaining ground.
