Gio Benitez is outside the hospital in New York, where doctors first noticed the alarming trend.

Good morning to you.

Hey, Robin, Good morning to you.

The doctor here at Mount Sinai says that some of these patients waited too long to come to the hospital because they were afraid of going in.

Now, this morning, he is sounding the alarm.

This'll morning, a disturbing observation doctor seeing strokes in young patients infected with the novel Corona virus.

What's worse, these were people quarantining at home, most with mild symptoms.

These patients were all in their thirties and forties to had no underlying conditions.

These are not particularly sick patients.

Neurologist Dr Thomas Oxley is behind a case report to be published in the New England Journal of Medicine, which called it an urgent communication on effort to rapidly notify the medical community of these findings.

He and his colleagues at Mount Sinai in New York saw Five Cove in 19 patients over the course of two weeks who were under age 50 presenting with strokes at the hospital.

When did you start noticing that blood clots were an issue?

I did buy these procedures weeks ago, and it was in a young patient with no past history.

Have been at home with Kobe, and so that struck me is unusual.

And then we saw a run of patients in same category.

Strokes are caused by blood clots.

Chinese doctors have reported clotting among Covad patients, and now American doctors to 49 year old Michael Reagan thought he was recovering from Cove in 19.

But scans of his lungs showed multiple blood clots.

So you're feeling pain in your lungs?

Yes, intense pain like I would imagine.

Ah, heart attack would be like I am in my forties.

I have run marathons.

I was a yoga instructor.

Begin.

And if I can get this still from it, anybody now?

Doctors at Mount Sinai making the decision to treat as many patients as they can with high dose blood thinners before they even see evidence of plotting.

Now needless to same or research is needed.

But the doctor says that if you have any symptoms of a stroke, so that's arm weakness.

Facial droop, speech, disturbance, call 911 Right away.

Amy and Michael eso important, Geo.

Thank you.

This is very scary to hear and see.

And so let's check in with Doctor Jennifer Ashton now for some expert opinion about this.

So how concerning are these findings to you, Dr Jen?

Well, Amy, it's painting a picture of some of these critically ill covert patients as being incredibly sick and challenging to take care of their showing features that air perplexing and a typical in viral illness that people are still trying to make sense of.

And remember, it's not just stroke when you talk about neurological effects.

Data out of China suggested there were things like headaches, seizure, dizziness, loss of smell and taste seen in as many as 36% of covert 19 patients presenting to the hospital and Dr Office.

All throughout this pandemic we've hit, we hear that people with underlying conditions fall most seriously ill from Corona virus.

But now there's a study proving it exactly just released last night, Michael in JAMA, the largest US clinical case, Siri's almost 6000 patients in New York state showing and take a look at these numbers.

Those admitted to the hospital.

Definitely more high risk.

57% of them came in with a preexisting diagnosis of high blood pressure hypertension, 41% with obesity and 34% with Type two diabetes, making them much more high risk for complications.

And Dr Jen, it's important to know you have been reporting that Kobe, 19 has the potential of impacting the entire body.

Correct?

That's right.

Literally head to toe Amy.

Brain, heart, lungs, kidneys, intestinal tract skin.

We are seeing head to toe manifestations, and so far, this virus really looking like a bad actor.

All right, Dr John Ashton.

We appreciate.
