Dr. Daniel Del Portal says they've been prepared as COVID-19 cases are going up by 10% each day.
They've converted an 8-story building on campus for COVID-19 treatment and put up a tent hospital just outside of the ER.
"We'll get to a point where everyone knows somebody who has been infected and gotten sick from it. This feels like a mass casualty event in slow motion. Anyone that comes in, we're treating them as if they have the virus," said Del Portal.

At times he's seen patients rapidly decline.
"When I say distress, it's to the point to where you are gasping for air," said Desrochers,

So does social distancing.
"I know it's tough for people but in the grand scale, staying home for a couple of weeks is small in order to flatten this epidemic," Del Portal sys.
