Timeline: How China's new coronavirus spread

The World Health Organization (WHO) has declared a global health emergency over a new coronavirus that has killed at least 425 people in mainland China and infected thousands of others, with cases confirmed in the Asia-Pacific region, Europe, North America, and the Middle East.

Below is a timeline.

On December 31 last year, China alerted the WHO to several cases of pneumonia in Wuhan, a port city of 11 million people in the central Hubei province. The virus is unknown.

Several of those infected worked at the city's Huanan Seafood Wholesale Market, which was shut down on January 1.

As health experts worked to identify the virus amid growing alarm, the number of infections exceeded 40.

On January 5, Chinese officials ruled out the possibility that this was a recurrence of the severe acute respiratory syndrome (SARS) virus - an illness that originated in China and killed more than 770 people worldwide in 2002-2003.

On January 7, they announced they had identified a new virus, according to the WHO. The novel virus was named 2019-nCoV and was identified as belonging to the coronavirus family, which includes SARS and the common cold. Coronaviruses are common and spread through being in proximity to an infected person and inhaling droplets generated when they cough or sneeze or touching a surface where these droplets landed and then touching one's face or nose.

On January 11, China announced its first death from the virus, a 61-year-old man who had purchased goods from the seafood market. Treatment did not improve his symptoms after he was admitted to hospital and he died on the evening of January 9 when his heart failed. 

On January 13, the WHO reported a case in Thailand, the first outside of China, a woman who had arrived from Wuhan.

Meanwhile, a Chinese expert on infectious diseases confirmed human-to-human transmission to state broadcaster CCTV, raising fears of a major outbreak as millions travel for the Lunar New Year holiday.

Asian countries ramped up measures to block the spread of the virus, introducing mandatory screenings at airports of all arrivals from high-risk areas of China.

On January 22, the death toll in China jumped to 17 with more than 550 infections. Many European airports stepped up checks on flights from Wuhan.

Wuhan was placed under effective quarantine on January 23 as air and rail departures were suspended.

The same measures were announced for two more cities in Hubei province: Xiantao and Chibi.

Beijing cancelled events for the Lunar New Year, starting on January 25, while officials reported the first death outside of Hubei.

The WHO said later on January 23 that the outbreak does not yet constitute a public emergency of international concern and there is "no evidence" at the moment of the virus spreading between humans outside of China.

By January 24, the death toll in China stood at 26, with the government reporting more than 830 infections.

The number of cities under lockdown in Hubei rose to 13, affecting 41 million people.
