Health officials warn Americans not to let their guard down

(AP) — Top U.S. health officials are warning Americans not to let their guard down against the coronavirus just because a vaccine could be on its way in a matter of days.

With an epic, coast-to-coast surge under way, authorities are urging people anew to wear masks, practice social distancing and follow other basic measures.

Most of California, meanwhile, is heading back into lockdown Sunday night.
