Let's get back to Dr Jen Aston.

Who's with us?

We've been tracking your questions and jen so much attention on the testing in this country.

We know it's far behind.

We have established that by now.

Not only would it help individuals know whether they have it or not put families at ease or know whether they need help, But it would also help us track surveil as it moves across the country.

So important, David, because we need to be able to identify, isolate, diagnose and then treat cases.

So knowing how many people are infected will help us know how many have symptoms.

Hominy don't have symptoms.

We need that data desperately.

It will help us track the hot spots as they move.

In the meantime, so many people tweeting both you and me about underlying health conditions and the real concern people.

And again, that list is growing.

But I want people to take a look at this list.

In general, it's people with preexisting high blood pressure, diabetes, heart, lung, kidney disease or otherwise weakened or compromised immune system.

They are a greater risk, but again we are seeing some cases in previously healthy people.
