I'm Carl Azuz at the CNN Center.

Today's show starts with the number 780 million.

That's almost half the population of China.

It's more than twice the population of the United States, and 780 million is the number of Chinese under some form of travel restriction as their government tries to stop the spread of the Wuhan coronavirus.

As we've reported its spread around the world, but China has been hardest hit: 70,000 people there have been infected with the virus, 1,770 have died there from it.

That's about 2.5 percent of those who catch the disease in China.

Deaths have also been reported in Hong Kong, the Philippines, Japan, and France, and cases have been reported in more than 24 countries on almost every continent.

There's no vaccine or cure for the new coronavirus.

Some people get severe symptoms and develop pneumonia.

Some people have almost no symptoms at all, and quarantines have been put in place in China and abroad in an effort to protect those who don't have it from those who do.

Aboard the Diamond Princess—that's a cruise ship that's been docked in Japan for two weeks—at least 456 people have tested positive for the corona virus.

There were roughly 3,700 people aboard in total.

More than 300 Americans who were on the ship have been allowed to travel back to the U.S., but they'll reportedly be quarantined again on American soil for another 14 days.

The World Health Organization, which is part of the United Nations, is not officially classifying the new coronavirus as a pandemic, a disease epidemic that spreads throughout the world.

Officials there say they're not seeing the virus spread widely in individual communities outside of China, but for those inside China, the scenes are eerie and the economic impact is growing.

You're looking at the post Lunar New Year holiday rush on the streets of Beijing.

Most years you'd see millions of migrant workers pouring back into China's capital, but this year a much slower pace and thin crowds.

The normally bustling shopping districts, desolate on the outside at least.

And think you'd find more life indoors?

Health checkpoints like this one screen people at every entrance of this shopping mall.

Sanitized only to enter a sterile and near empty space.

On any other given Sunday, especially in winter, malls like this one would be packed with people; instead, we're pretty much the only ones here.

Popular Beijing restaurants like this one known for their Sichuan cuisine have no need to change out the white table cloths for weeks.

Many are scared to even talk face to face to others let alone share a meal with them.

But there's still a need to make money, and there's still a demand for fresh produce.

Instead of wasting their supplies, the restaurant staff has set up tables outside their storefront creating a makeshift farmer's market of sorts.

They can't operate because of the epidemic so they need to sell out the stocks.

It's convenient for customers like Zhang Rui.

He's been working remotely in IT for about a week.

His company like many here in Beijing encouraging their employees to work from home, but he's noticed a slump in company productivity.

It's not as efficient as working in the office because it's not very convenient if colleagues are not physically together.

Zhang is still among the fortunate ones.

The outbreak's left many without jobs to clock into.

Huang Keyun video chatted with us from Anhui in Central China.

She, like many migrant workers, had expected to travel back to Beijing to return to her job as a nanny.

My boss told me that he would leave for America.

I asked him when he would come back, but he said he might not return.

Now jobless, she's living off the two months of extra pay her former employer provided her, but that's draining with each passing day.

I just stay at home, don't go out.

And the government asks us not to go out as well.

I just stay at home with my family.

And even if she wanted to return to Beijing immediately, she would be expected to self-quarantine for two weeks.

That's two more weeks without pay.

Many migrant workers facing similar financial struggles as the government's efforts to stop the spread of the virus intensify.

For now, at least, there is no containing the growing economic uncertainty.

10 Second Trivia.

What animal would you find in the family Acrididae?

Aphid, marmot, sea horse, or locust.

In the family acrididae you'll find grasshoppers and locusts.

Imagine seeing an approaching cloud that's massive, 37 miles long and 25 miles wide, and instead of water or dust, it's a cloud of locusts.

That's the size of just one of the swarms that's descended this year on Eastern Africa.

Specifically, these are desert locusts, the most destructive type of locusts that eats food and that's terrible news in a region that's food insecure, meaning there are already problems with people getting enough to eat.

The United Nations says this is the worst invasion of desert locusts in 25 years.

What might have made it so bad was a cyclone, a major storm that hit parts of Somalia and Ethiopia last December.

That brought a lot of rain to the region, and that creates the best conditions for these pests to breed.

The United Nations wants the world to contribute more than 75 million USD so pesticides can be sprayed to kill the insects.

Ravenous and ruthless, locusts have been known and feared by the world's most ancient civilizations, but their biblical infamy is all too real today.

Right now, millions of these insects are sweeping across the farm lands of East Africa.

Some reports say there are billions, destroying crops and threatening livelihoods.

For farmers across the region this is the sound of danger.

We depend a lot on this season, and we worry that the locusts will destroy our harvest, and we will end up remaining hungry throughout the rest of the year, waiting for October when we have the next cropping season.

This years locust's invasion is so bad that the UN is warning of a serious food crisis in Ethiopia, Kenya, Uganda, Tanzania, and Somalia.

The UN's Food and Agriculture Organization says massive food assistance now maybe needed.

There's already 13 million people in that region that are in acute food insecurity.

This is just one level below famine.

75 percent of those people live in areas that are now currently infested with desert locust.

Somalia has already declared a national emergency, and the UN warms this could become the most devastating plague of locusts in living memory if the world doesn't step up against the onslaught.

We have a very small window in order to achieve this before the next planting season.

If we don't get the help that we're appealing for or for some reason the control operations are not successful, the locust they just continue to breed.

And between now and June there could be a 400-fold increase of locust.

Climate experts are blaming unusual heavy rainfall and cyclones, which provide ideal environments for rapid breeding for this year's massive swarms.

And with wetter and hotter weather than usual forecast until May, they warn the worst is yet to come.

A long-lost purse found in an Ohio school wall is like a time capsule from the 1950s.

It was found in May of 2019 by a custodian repairing wall trim at North Canton Middle School.

It belonged to Patti Rumfola, a former student who lost it in 1957.

Rumfola died in 2013, but the purse's contents gave her family a glimpse of her life as a teen.

The clutch contained several black and white photos, presumably of family and friends.

Inside were also makeup items, a comb, school supplies and a football game schedule.

(The purse also held 26 cents, which became special mementos for her children).

The school said each of her five children kept one of the pennies.

10 out of 10.

Well even though this happened in February, it was time to own the night like the 4th of July because baby it's a firework.

The Guinness World Record for the biggest one ever.

Its shell was more than five feet in diameter, and it weighed 2,800 pounds, as much as a compact car.

It took explosives to get the thing off the ground, but once it did, it lifted almost a mile high before onlookers in Colorado were left in awe, awe, awe.

It was even brighter than the moon, moon, moon, and it's no wonder why when the colors burst viewers got such a "charge" out of it.

Critics might have called it a waste of space, but when its makers ignited the light and let it shine it would be "okatie" to say it was "perry impressive".

If you're not familiar with that song, those puns are a total dud.

But our viewers in Sioux Falls, South Dakota aren't.
