Microsoft co-founder and philanthropist Bill Gates said Sunday that while the coronavirus pandemic was a “nightmare scenario,” continued social distancing measures would likely flatten the virus’s trajectory by the end of April.

"If we had kept on going to work, traveling like we were, that curve would never bend until you’d had the majority of people infected," Gates said on “Fox News Sunday.”

"We’ve had to use quarantine, which is an old thing back from the days of the plague, as our primary tool," he added. "Fortunately, if we use that well enough, we should by the end of this month start to see those numbers level off."

“It’s very important that those numbers are out there because a lot of people are still thinking, ‘Hey, isn’t life normal?’ not waking up every day to a completely new reality,” he added.

“Things won’t go back to truly normal until we have a vaccine that we’ve gotten to basically the entire world,” he added, noting that, as was the case in China, there would likely first be a “partial opening up.”

“Some jobs will resume, school will partially resume, but we’ll have to be very, very careful not to have the rebound until the vaccine comes,” he added.
