Dr. Michelle Barron, an infectious disease specialist at UCHealth University of Colorado Hospital, on Wednesday likened preparing for the spread of the new strain of coronavirus within the United States to preparing for a hefty winter snowstorm. “It’s appropriate to say we will probably see more cases in the U.S. and throughout the world, but I don’t think that should set off an alarm,” said Barron, the medical director of infection control and prevention at UCHealth University of Colorado Hospital.
