For weeks after the first reports of a mysterious new virus in Wuhan, people poured out of the central Chinese city, cramming onto buses, trains and airplanes as the first wave of China's great Lunar New Year migration broke across the nation. Some carried with them a new virus that has claimed over 560 lives and sickened more than 28,000 people.
