Thanks for watching CNN 10.

With the year of school at work, on the road or at home, you can always find us at youtube dot com slash CNN tent.

We know a number of our viewers are at home today, with certain schools and universities across the world either closed or holding online classes on Lee.

Concerns about the novel or new Corona virus have led to shutdowns of places where people gather parades and concerts have been called off.

Some international soccer games have been played in empty stadiums.

Flights have been canceled with fewer people traveling.

We told you yesterday how the nation of Italy, which has seen the most Corona virus cases in Europe, went on lock down.

Public events there are banned travel is restricted because the virus has been spreading so fast, it's difficult to keep up with all of the country's announcing similar restrictions and attempts to contain the disease.

After Monday's record setting point drop in the U.

S.

Stock market, there was a rebound yesterday after the Trump administration started discussing a payroll tax cut that would be intended to put more money in the hands of working Americans and help ease the economic consequences of the virus.

Other countries governments are also looking for ways to do that.

As of yesterday afternoon, there were at least 849 confirmed cases in America.

They stretched across most states, and the District of Columbia, California, New York and Washington.

Each had more than 100 reported cases.

There's a lot that health officials don't know about this disease, but early data indicates that older people are twice as likely to get seriously sick from it.

Americans are being encouraged to avoid shaking hands and sharing food, to disinfect door knobs to regularly clean utensils and especially to wash your hands.

Since the novel Corona virus first appeared in Wuhan, China, in late 2019 it has spread across the world, leading the thousands of death sadly and tens of thousands of infections.

Limiting transmission between individuals is vital to help contain the outbreak.

So here's what you can do to protect yourself.

Health experts agree that you should wash your hands regularly thoroughly as well, with soap and water for at least 20 seconds.

Don't forget your thumbs.

Don't forget beneath your nails now soap and water or not available.

You can use a hand sanitizer to make sure that it's a least 60% alcohol.

Do avoid close contact with anyone who is coughing or sneezing.

What you're trying to do is avoid the airborne droplets that can spread the disease.

Avoid touching your face at all.

We do this hundreds of times a day.

Avoid touching your face, but especially with unwashed hands as the virus can enter your body through your eyes, your nose and your mouth.

If you do cough or sneeze, don't do it into your hands.

Instead, use the crook of your elbow or use a tissue unless you're already sick.

Don't wear a mask.

This is important.

Wearing a mask can actually increase your risk of getting infected if you wear that mask improperly.

Individuals do have an important role to play here, but society wide measures.

We're also gonna help stem the global spread of this virus.

While affected countries have used a range of responses, containment efforts can be effective here.

The lock down of the entire city of Wuhan is thought to have helped slow the initial spread of the virus, and that bought valuable time for preparations elsewhere.

Since then, large scale quarantines have been used in some of the worst affected areas in the world, including Italy's Lombardy region.

I should point this out that large quarantines have not really been used in the United States for decades.

The world has changed a lot since then, so it is hard to know just how effective these quarantines would be today.

Restricting large gatherings of people may also help prevent the transmission of this virus.

For example, baseball games played in empty stadiums in Japan, Italy ended the Venice carnival early.

At least one fashion show in Milan was held with no audience at all, while France also closed public spaces, including the loot.

Early detection of cases through testing, that's the key, and some countries have taken it to the next level.

For example, in China, they quickly deployed thermal monitoring technology to record temperatures.

And in South Korea they pioneered further innovations like drive thru.

Testing from providing emergency resource is an investment to building infrastructure at speed.

Governments around the world now are working to contain and then mitigate this outbreak, and the vast majority of people who contract the virus do recover So while novel Corona virus and the anxiety about it continue to spread, remember, there are things that can be done to fight back.

Second trivia.

What do Michigan, Mississippi and Missouri all have in common?

Are they all east of the Mississippi River west of the River States prior to 18 50 for part of the Louisiana purchase?

All of these states were admitted to the union before 18 50 and yesterday they were all also part of Super Tuesday to or Super Tuesday.

Two point.

Oh, whatever you call it.

It involved six states and total five.

We're holding primaries.

One was holding caucuses.

It came exactly one week after Super Tuesday and wasn't as big in terms of delegates at stake.

But it was the next big step in the process that will determine which Democrat and which Republican will be listed on the U.

S.

Presidential ballot this November 3rd, while incumbent President Donald Trump is dominating the Republican races over former Massachusetts governor Bill well, there are three Democrats competing for their party's nomination, and the two front runners were very close to each other in terms of the delegates they'd won going into yesterday's contest.

Former Vice President Joe Biden had 635 pledged delegates.

U.

S Senator Bernie Sanders from Vermont had 558.

We didn't have results when we produced this show, but the big prize from Super Tuesday to was Michigan.

In that state, 125 delegates were at stake wrapping up in New York City, which has held a number of superlatives when it comes to height in 1929 the Chrysler Building was the tallest in the world.

Two years later, the Empire State Building took that title from it.

And now one World Trade Center is the tallest in the city, though not the world.

But not every high point is a skyscraper.

Sometimes it's a sky deck.

Oh, you can see the entire city all in one shot, everything from the Statue of Liberty all the way around the Central Park.

And it really is the only place in the city where you get a view of all of the major icons in the whole city.

In one shot in one breath, we're standing on the glass floor, and this is probably one of the best spaces that we have.

If I look down, I can look down over 1100 feet straight down to 10th Avenue.

And this is really a unique view on a unique experience.

You can stand, look around, see the cars going by.

I think a lot of people will lay down, take Selfies from above.

This will become the iconic shot.

Once you get up to the top, we're not going to really be encouraging people to leave.

We're really gonna let people experience of how they want to.

Some people will come up very quick.

We know during sunset time people will stay a bit longer.

But we're gonna really let it feel organic and not try to manage people once they get up to the top.

These are very, very strong glass pieces and structurally designed so that there is no way that we could put enough people on here to be anywhere close to any weight.

So perfectly say we could have everybody all over looking down.

No problems at all.

When you look out, you don't see any railings and bars, anything like that.

Glass itself is the structure that was really designed for a number of reasons.

but the main one is given unobstructed.

You know, we call ourselves edge when you walk out, it really is like you can walk off to the We really don't want people to think of us as an observation that way.

Have a number of experiences that were really trying to be more than that and really give a different type of experience.

This is really about having unique elements that are unique to us.

Here at Hudson Yards and unique Thio Edge and looking down to the city is something that it's the only place you'll be able to do it in New York or New Amsterdam.

The cutting edge may leave thrill seekers glassy eyed, and while some will like it because it's edgy and others will be put on edge, you too might not like people walking all over the edge.

And acrophobic certainly won't want to hit the deck.

They'd rather stay below deck and keepem or grounded altitude about the viewing party above.

Even if the edge is the height of observation post, it's great to have Trinity Lutheran school watching today.

It's an Aberdeen, South Dakota, the one place CNN is looking for The schools we mentioned is on our YouTube channel.
