They've gotten infected with this virus, but never had any symptoms.

New reports are coming out suggesting that maybe a whole lot of people are like this.

Large number of Americans could be walking around with coronavirus and not even know it.

How many asymptomatic cases are out there and how could they spread it?

That's what we're going to dive into today.

And the stakes are high.

If there are a bunch of people like Mark walking around not knowing they're sick, does that mean we've got a swarm of silent spreaders on our hands?

When it comes to this coronavirus, there's a lot of weird.

But then there's science.

Science versus silent spreaders is coming up just after the break.

Today on the show, silent spreaders.

How many people who get infected with this virus don't show any symptoms?

And this question really matters because we're learning that some people can spread this virus even when they don't feel sick.

They have the virus in their nose and throat and they can be shedding it.

So we really need to know how common it is to be asymptomatic.

Because when we hear big numbers in the news suggesting that one in four New Yorkers have had this, it sounds like heaps of people must be walking around with no symptoms.

But is that right?

So these numbers are coming from a new kind of testing that's being rolled out in the US and other parts of the world, and it's getting a lot of buzz.

Antibody testing.
