(Reuters) - The coronavirus outbreak that began in the central Chinese city of Wuhan has killed 56 people in China and infected more than 2,000 globally, most of them in China.

The virus has caused alarm because it is still too early to know how dangerous it is and how easily it spreads between people. And because it is new, humans have not been able to build any immunity to it.

Here is what we know so far:
