In a press conference, Wuhan's mayor Zhou Xianwang confirmed that five million people had travelled out of Wuhan, before January 23, when large-scale travel restrictions were placed on the city, South China Morning Post reported.

Why did people travel out of Wuhan in such large numbers?

One of the reasons is to avert being infected by the deadly novel coronavirus (2019-nCoV) that has caused havoc in the city, since December.

Another reason is China's annual Lunar New Year Holiday, from January 24-30, in which millions of Chinese travel both domestically and abroad. For many workers, it's the only time when they get to go home, explaining the desperation to travel in the face of an impending quarantine.

Taking into account the mounting cases, the government has extended the holidays till February 2. Almost all the cases confirmed outside Wuhan are of persons who had recently arrived from Wuhan or had come in direct contact with them.

As on Tuesday, 106 persons have lost their lives and over 4,500 cases have been confirmed by China. About 50 cases have been reported outside China, with cases being reported as far away in North America, Australia and Europe.
