CNN News:钻石公主号游轮新冠病毒感染人数达456人

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 corona virus. As we've reported it's spread around the world but China has been hardest hit, 70,000 people there have been infected with the virus, 1,070 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 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 corona virus. 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 corona virus 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.
