The US accounts for the most cases; Italy the highest death toll.

How did we get here?
At the end of December, 34-year-old ophthalmologist Dr Li Wenliang tried to send a message to other medics warning them about a new virus in Wuhan, in China's Hubei Province.
He was later visited by the police accused of scaremongering.
On 3 January we wrote our first news report about a "mystery virus" in Wuhan. At the time, 44 cases had been confirmed, 11 of which were considered severe. There had been no deaths yet, but many feared we would see a repeat of the 2003 Sars outbreak that killed 774 people. By 18 January the confirmed number of cases had risen to around 60 - but experts estimated the real figure was closer to 1,700.
Just two days later, as millions of people prepared to travel for the lunar new year, the number of cases more than tripled to more than 200 and the virus was detected in Beijing, Shanghai and Shenzhen.
