U.

S President Donald Trump delivered a speech from the Oval Office this week.

His goal was to discuss what the United States government was doing to protect Americans from the new Corona virus and to reassure them that it would eventually pass.

We have been in frequent contact with our allies, and we're marshalling the full power of the federal government and the private sector to protect the American people.

This is the most aggressive and comprehensive effort to confront a foreign virus in modern history.

I am confident that by counting and continuing to take these tough measures, we will significantly reduce the threat to our citizens, and we will ultimately and expeditiously defeat this virus.

So what are some key parts of that effort?

The president says with some exceptions, travel from Europe to the United States will be suspended for a month.

Health industry executives have agreed to make Corona virus treatments cheaper and easier to get.

Tax relief is ahead for some businesses that are losing revenue because of the pandemic.

The president says no nation is more prepared or resilient than the United States.

But some Democrats and Republicans on Capitol Hill were questioning that prepared this yesterday.

One issue they had was with Corona virus testing.

They say it's not as widely available in America as it is in some other countries, like South Korea, and that that's a problem.

As the disease spreads, its effects are spreading as well.

The U.

S capital is now closed to visitors.

The Metropolitan Museum of Art has closed.

The National Basketball League has suspended all of its games.

The National Hockey League announced the same thing yesterday.

Major League Baseball has suspended spring training.

March madness has been cancelled.

Disneyland is closed.

Around the world, there have been cancellations.

Enclosures like these, sometimes including country's borders and international stock markets, have seen dramatic swings and losses because of this week's drops in U.

S.

Stocks, wall Street is now said to be in bear market territory.

So we talk about being in a band market.

People would panic.

The market is not functioning properly.

What exactly is a bear market?

It's when stocks dropped 20% from recent highs.

When we talk about the overall stock market, we usually look at a broad index like the S and P 500.

But individual stocks or commodities can also fall into a bear market if they decline 20% now.

A bear market is different from a correction.

That's a 10% decline.

So if the S and P falls into a bear market, it's already had a correction and then fall in another 10%.

Since World War two, there have been 13 bear markets for the S and P 500.

A bear market doesn't always signal a severe economic downturn.

In the last 40 years, four bear markets have occurred without a recession, but the drops that coincide with recessions tend to be worse.

The good news is bear markets don't tend to last a long as bull markets.

The average lasted 362 days and declined nearly 32% but history shows it takes about a year for stocks to fully bounce back.

Second trivia.

Geographically.

Which of these nations is closest to Japan, China, North Korea, South Korea or Philippines?

The Korean Peninsula became independent from Japan in 1945 and South Korea is its closest neighbor, getting medical supplies to hospitals and people who need them.

Developing vaccines.

These air some actions being paid for by an $8.3 billion funding bill that President Trump recently signed into law.

Other countries are also spending millions to come up with a Corona virus vaccine.

And though one of those doesn't exist yet, testing kits do.

And as you heard earlier, South Korea has been seen as a model for Corona virus testing.

How can the efforts of a nation that's about the size of Indiana potentially benefit larger countries?

Since the start of the Corona virus outbreak, South Korea has aggressively tested for the disease with the help of DR through testing facilities that speed up the process.

South Korea has already tested more than 220,000 people.

Quick rollout made possible thanks to fast work by Korean biotech companies like See Jeanne, which gave CNN exclusive access to its research facilities.

This is the laboratory where a team of scientists came up with the test kit for diagnosing Corona virus, and they did it in under three weeks.

When we starting, we didn't expected this kind of the pandemic will operate happened in Korea.

Nobody expected at all.

Change on June is the founder and CEO of See Gene, a company that designs and sells test kits to identify at least 160 different kinds of diseases.

In mid January, Chun says, he first instructed his researchers to invent a new test for Corona virus, which was then starting its deadly spread across China.

So you guys were already working on Corona virus before the first confirmed case of the illness in South Korea.

Yeah, just hearing the news from the China, we thought it will be impacted on the Korean Peninsula.

So so today is emergent cases.

The molecular microbiologists got to work without ever having a physical sample of the virus.

Instead, they relied on a genetic blueprint of the new virus distributed by the World Health Organization and health officials in China, highlighting three specific genes.

See, Jane's scientists then had to come up with a way of spotting those Corona virus genes in future samples taken from patients.

Was there more pressure than usual?

Yeah, because it's an emergency case regularly spread in the corner of eyes into our countries.

Not long ago, it would have taken See Jean two months to a year to come up with the test.

But using artificial intelligence, you were able to come up with a test in less than two weeks, right?

That's pretty quick, Chun says.

On February 12th the Korean government fast tracked approval of the new Corona virus test kit less than a month after see James started working on it.

These six vials, some of which only contained a teardrop worth of solution or what you need to conduct tests on 100 patients for Corona virus and that could be completed in just four hours.

See, Gene is now working overtime, even drafting scientists with PhDs toe work on the assembly line.

That's how much demand there is right now.

You see, it's crazy event not only for the domestic market, so you know from the overseas market the demand is urgent because identifying Corona virus is one of the best ways to stop the spread of this disease.

Riveting Rescue of rock star Freddie.

Of course, it's worth 10 at a 10 Rock star.

Freddie is a teddy.

It belongs to a kindergartener in Florida.

But for some reason ah first grader threw it onto the roof of the school and the teddy Bear's owner was crushed.

But that's when the Cape Coral Fire Department got involved.

They were probably relieved.

Rock star Freddie wasn't the cat, and they pulled out all the stops to pull the teddy off the roof so they didn't need to raise the roof to save the stranded Teddy.

You, Betty, that they're ready when there's a bear need for Freddy.

They held steady and they didn't blush, even if the thing was plush.

Bet you that it's still a rush saving something stuffed.

Call it fluff.

Call it guff, but don't ever say they bluffed because Freddy is now home safe.

And for his owner, that's enough.

Pun wraps unbearable y'all of Carla Zeus, and today's show goes out to Palestinian Wheatley High School.

It's in Palestinian Arkansas.
