DENVER (AP) – Colorado Gov. Jared Polis joined the nation’s top infectious disease expert and urged people to wear masks and socially distance to prevent stay-at-home orders and overwhelmed hospitals as cases of the coronavirus surge during the holidays. Dr. Anthony Fauci warned Tuesday that Colorado isn’t alone in seeing a spike in cases. He pleaded with people not to travel or gather in large groups. He said the country will likely see “a surge upon a surge” of cases, based on the number of people who traveled for Thanksgiving. About one in 41 Colorado residents is believed to be contagious with the virus.
