What the end of the Covid-19 pandemic could look like

Covid-19 is here to stay.

It's highly unlikely that the United States, let alone the world, will be able to completely eliminate the coronavirus that causes Covid-19.

But there will come a day when it's no longer a pandemic, when cases are no longer out of control and hospitals aren't at great risk of overflowing with patients. Many experts predict the spread of coronavirus will look and feel more like seasonal influenza.

What's less clear is how and when that will happen.

"There's not even a measurement to say that something is an epidemic or pandemic. All of this is in the eye of the beholder -- and that's part of the issue," Dr. Arnold Monto, a professor of epidemiology at the University of Michigan and acting chair of the US Food and Drug Administration's Vaccines and Related Biological Products Advisory Committee, told CNN.
