Dr. Anthony Fauci, the U.S. government's top infectious disease expert, warned on Sunday that states without stay at home orders are putting themselves at risk for COVID-19 outbreaks.

"This is going to be a bad week," Fauci explained to CBS News host Margarett Brennan. "We're going to continue to see an escalation. We should also hope that within a week, maybe a little bit more, we should start to see a flattening out of the curve."

The doctor predicted that the death toll would be "shocking to some."

"I will not say we have it under control," he said. "That would be a false statement. We are struggling to get it under control."

Unlike President Donald Trump, Fauci said that he does wear a mask in public.

"If I go out which I really don't do very much because of my life as it is now, I would and do [wear a mask]," he explained. "If you have a situation where you don't have control over that six foot distance, you wear a mask."

Fauci also said that the eight states without stay at home orders are at greater risk for outbreaks.

"It isn't that they're putting the rest of the country at risk as much at much as they're putting themselves at risk," he remarked. "This virus doesn't discriminate whether you're in a small town in a relatively secluded area of the country vs. whether you are in a big city."
