From the newsroom of the Washington Post.

Hi there, is the Mayor, Marissa Lang with the Washington Post.

Hey, it's Dossie, order to pick your brain on the truck.

Hi, Wayne's, Janet Johnson.

This is Post Reports.

I'm Martine Powers.

It's Wednesday, April 29th.

Today, the lingering questions about coronavirus, the pressure on schools to reopen.

And North Korea is missing later.

So, Lenny, despite the fact that it seems like all we're doing every day is thinking and reading about coronavirus,

there are still a lot of things that we don't know about this outbreak and about how the virus works.

Or things that we thought that we knew a month ago or two months ago that now seem not quite so clear.

Yeah, it's a brand new disease, it's a brand new virus.

This is Lenny Bernstein. He covers health and medicine for the post.

And with the CDC adding six new symptoms to look out for, we wanted to ask Lenny some of the questions we've had about coronavirus.

What we're learning now and what we still don't know.

As we go through the pandemic, remember the pandemic?

Well, it seems like a century to all of us is maybe a month and a half old, depending on where you want to begin.

And it is showing itself to have characteristics that we're not expected and to have characteristics that are pretty dangerous to us.

So what are some of the surprising things that doctors have seen in recent weeks in terms of how this virus affects people's bodies?

I think one of the most surprising things is that some people appear to be able to walk around or to be hospitalized with relatively mild symptoms,
