CNN News:时值中国春节 武汉爆发冠状病毒

On the Chinese calendar the year 4717 begins in two days. It's known as Chinese New Year, Lunar New Year, Spring Festival — the celebration will last just over two weeks and it's the reason for the largest annual human migration on Earth. But it's coming with an additional concern this year that's having effects far beyond China. When we first reported on the Wuhan coronavirus earlier this week, the mysterious illness had sickened more than 40 people and killed two. Now health officials say 17 people have died from the disease and at least 540 cases have been confirmed in China. But that's not the whole story. Additional cases have been reported in South Korea, Thailand and Japan. There are suspected cases in Australia and at least one case has reached America with a virus patient in Washington State.
But several other cases are being tested in the United States and they involve people who either traveled to Wuhan or had close contact with someone else who might have the virus. It's named for a province of central eastern China where the disease was first detected in mid-December.

Most of the initial patients had been to a large seafood and animal market in Wuhan. A coronavirus can cause breathing problems and the Wuhan coronavirus has been causing pneumonia. And because it's spread across oceans international medical officials are trying to figure out what they need to do to stop it.
This could involve screening people who traveled to other countries, monitoring travelers more closely for symptoms of the virus and coming up with plans for treating the disease. It's timing is particularly bad for China. Hundreds of millions of people are traveling right now for Lunar New Year and they're often in close contact with others on trains and planes. In fact, Chinese officials have stopped transportation moving out of Wuhan for the time being.
