A SARS-like virus that has claimed 41 lives since emerging in a market in the Chinese city of Wuhan has spread around the world.
Here are the places that have confirmed cases of 2019 Novel Coronavirus:
As of Saturday, almost 1,300 people have been infected across China, the bulk of them in and around Wuhan.
Nearly all of those who died were in the Wuhan region, but officials have confirmed two deaths elsewhere.
The city of Macau, a gambling hub hugely popular with mainland tourists, has confirmed two cases.
In Hong Kong, five people are known to have the disease. Three of those cases were confirmed in the 24 hours to Saturday morning.
There are three known cases of the coronavirus in France, the first European country to be affected by the outbreak.
One person is sick in Bordeaux and another is ill in Paris. A third person, who is a close relative of one of the other two, has also been confirmed to have the virus.
All three had recently travelled to China and had now been placed in isolation.
Japan's health authorities confirmed a second case on Friday. Local media said the patient was a man in his 40s who was originally from Wuhan and on a trip to Japan.
The country's first case was reported by the health ministry last week: a man who had visited Wuhan and was hospitalised on January 10, four days after his return to Japan.
Australia on Saturday confirmed its first case of the virus, a man who arrived in Melbourne from China a week ago.
Authorities said they were contacting people who had travelled on the same plane from China and offering advice.
Malaysia confirmed its first three cases on Saturday. All are Chinese nationals on holiday from Wuhan who arrived in the country from Singapore two days earlier.
A 66-year-old woman and two boys, aged two and 11, are in a stable condition and are being kept in an isolation ward at a public hospital, Malaysia's health minister said.
Nepal said a 32-year-old man arriving from Wuhan had the deadly disease.
The patient, who was initially quarantined, recovered and was discharged. The government said that surveillance has been increased at the airport "and suspicious patients entering Nepal are being monitored".
Singapore has announced at least three cases -- a 66-year-old man and his 37-year-old son, who arrived in Singapore on Monday from Wuhan, and a 52-year-old Wuhan woman, who arrived in the city-state on Tuesday.
South Korea confirmed its second case of the virus on Friday.
The health ministry said a South Korean man in his 50s started experiencing symptoms while working in Wuhan on Jan 10. He was tested after his return earlier this week, and the virus was confirmed.
The country reported its first case on January 20 -- a 35-year-old woman who flew in from Wuhan.
Both remain in treatment and are in stable conditions.
Taiwan has uncovered three cases so far. It has since advised against travel to Wuhan and Hubei province and on Friday said any arrivals from Wuhan would be rejected by immigration.
All arrivals from the rest of China -- including Hong Kong and Macau -- must fill out health declaration forms on arrival.
It has also banned the export of face masks for a month to ensure domestic supplies.
Thailand has detected five cases so far -- four Chinese nationals from Wuhan and a 73-year-old Thai woman who came back from the Chinese city this month.
Two of the Chinese patients were treated, and have since recovered and travelled back to China, the Thai health ministry said this week.
On Tuesday US health officials announced the country's first case, a man in his 30s living near Seattle. On Friday a second case was announced -- a woman in her 60s living in Chicago.
Both were treated and are recovering.
Vietnam confirmed two cases of the virus on Thursday. An infected man from Wuhan travelled to Ho Chi Minh City earlier this month and passed the virus on to his son.
Both are being treated in hospital and are stable, Vietnam health officials said.
