The coronavirus outbreak that began in the central Chinese city of Wuhan, in the province of Hubei, has killed 106 people in China so far and infected more than 4,520 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. Also because it is new, humans have not been able to build immunity to it.
Here is what we know so far:
* As of Jan. 27 the death toll in China had risen to 106, with 100 in Hubei province, authorities reported. Another 4,515 people in China had been infected. There were 2,714 confirmed cases in Hubei province, up from 1,423 on Jan. 26.
