An article on the BBC website offers 10 maps and graphics designed to explain the coronavirus outbreak.
Across China, tens of thousands of people have been infected with the coronavirus, which causes pneumonia-like symptoms. Thousands more are under medical observation.
The virus has killed more than 2,000 so far - more than the 774 killed in the 2003 Sars epidemic.
There was also a significant increase in the number of cases reported on Feb.13 . This increase is mostly due to a change in the way patients are being diagnosed in Hubei province - the center of the outbreak.
