Scientists likely underestimated the “number of asymptomatic cases” of the novel coronavirus, Dr. Deborah Birx said Saturday night.


“I think we’re learning every day about the virus and how it interacts with us as human hosts,” Birx, the White House coronavirus response coordinator, said during an appearance on Fox News’ “Justice with Judge Jeanine.”

“And that’s been very important, to constantly be triangulating data,” she added. “I think we underestimated, very early on, the number of asymptomatic cases. And I think we’re really beginning to understand there are people that get infected — that those symptoms are so low-grade that they don’t even know that they’re infected.
