The Chinese city of Wuhan, with eleven million people, has temporarily shut public transport as it tries to halt the outbreak of a new strain of virus.
Trains, planes and all public transport have been suspended and all public gatherings cancelled as number of infections rises to 571 with 17 deaths so far.
Those living in the city have been advised not to leave.
The respiratory illness has spread to other parts of China, with some cases in other countries including the US.
But the World Health Organisation is yet to declare the Wuhan Coronavirus a public health emergency of international concern.
