The Wuhan coronavirus has spread throughout the world since the first cases were detected in central China in December. At least 427 people have died and more than 20,600 people have been infected, and the World Health Organization (WHO) has declared the outbreak a public health emergency of international concern.
China's National Health Commission has confirmed the virus can be transmitted from person to person through "droplet transmission" -- where a virus is passed on due to an infected person sneezing or coughing -- as well as by direct contact.
There are more than 200 confirmed cases of Wuhan coronavirus in more than 25 countries and territories outside mainland China. Two people have died outside of mainland China from the virus -- a 44-year-old Chinese man in the Philippines, and a 39-year-old man in Hong Kong.
A number of countries, such as the United States and Japan, have evacuated their nationals on flights from Wuhan, capital of Hubei province.
This is a full list of places outside mainland China with confirmed cases of the Wuhan coronavirus.

She started having symptoms on January 24 and was assessed and tested that same day, the Ministry said.
The woman initially tested negative at the laboratory, where an original test was done. A second test performed several days later, in response to a new pathogen, came back weakly positive, and the switch from negative to positive was made on a precautionary level, according to Dr. David Williams, Chief Medical Officer of Health in Ontario.
A Canadian couple tested positive in Ontario -- both the man and woman had visited Wuhan before getting ill.
The Canadian government has warned its citizens against all travel to Hubei province. It said the risk of the new coronavirus spreading within Canada remained low.

On Saturday, CNN reported that the father -- aged 33 -- is an employee at a company in the district of Starnberg, where six other employees previously tested positive with the deadly virus.
Hong Kong (at least 17 cases, 1 death)
The semi-autonomous city of Hong Kong, which borders mainland China, has reported its first death from the coronavirus.
The 39-year-old man died Tuesday at Princess Margaret Hospital and had an underlying illness. The patient took the high-speed train from Hong Kong to Wuhan on January 21 and returned to the city from Changshanan on January 23. He was said to have never visited any health care facilities, wet market or seafood market, or had any exposure to wild animals during the incubation period.
Hong Kong has temporarily closed some of its borders with China and stopped issuing travel permits to mainland tourists.
West Kowloon Station, where high-speed rail runs between the city and mainland China, is closed until further notice. Half of all incoming flights from China have been canceled. Residents of Hubei province, where the virus was first reported, are also being denied entry to the city.
Most government offices, except those involved in emergency and essential services, will be closed for the rest of the week. All schools will also be shut until at least March 2.
This comes as Hong Kong recalls painful memories from the severe acute respiratory syndrome (SARS) outbreak in 2003, a pandemic that killed more than 280 people in the city.
India (at least 3 cases)
India confirmed its third case of coronavirus on Monday in Kerala.
The third case is a student who tested positive for the virus after returning from Wuhan, according to a Facebook post from Kerala Health Minister KK Shailaja. The student has been admitted to a district hospital in Kerala and is in stable condition.
Italy (at least 2 cases)
Italy has confirmed two cases of coronavirus, Italian Prime Minister Giuseppe Conte said at a news conference in Rome on Thursday.
The individuals affected are two Chinese tourists who had arrived in Rome a couple of days previously, Conte said.
"We have already prepared all the precautionary measures to isolate these two cases," Conte said.
Italy's Health Minister Roberto Speranza said the government would try to trace the tourists' journeys while in Italy, adding that the situation was serious, but under control.
"The timeliness of the intervention makes us think that there are no other people exposed," Ippolito said.
Japan (at least 20 cases)
Japan's Health Ministry confirmed three additional infections with the new coronavirus on Saturday, raising the total domestic tally to 20.
The new cases are among the 565 Japanese nationals who returned from Wuhan on government-chartered flights earlier in the week. Among the confirmed cases is a man aged in his 30s who has been diagnosed as a disease carrier without symptoms.
At least two people with the coronavirus in Japan have no travel history to Wuhan. One, a man in his 60s, is a bus driver who drove tour groups from Wuhan for nine days before getting ill. His is the first case of suspected human-to-human transmission in Japan.
A third plane carrying Japanese evacuees from Wuhan arrived in Tokyo on Friday.
Notably, the Japanese flights also carried medical supplies for the Chinese government. They included thousands of surgical masks, safety goggles and 50 sets of protective suits.
Macao (at least 10 cases)
Macao has confirmed at least 10 cases of the Wuhan coronavirus.
The semi-autonomous city in southern China will suspend operations of gambling and related industries for half a month, Chief Executive Ho Iat Seng said at a news conference on Tuesday.
Macao officials told CNN it has not been decided yet when this suspension will start as the chief executive will meet with gambling companies Tuesday.
The outbreak has had a devastating impact on tourism in the gambling enclave, which relies heavily on mainland Chinese visitors. Gambling is illegal on the mainland and Lunar New Year is usually a particularly busy time for Macao's casinos. But not this year -- tourism to the city has dropped 73.6% year-on-year, the Macao government announced on January 29.

The patient is part of a group of five people that health officials on the island say are "under observation" after being in contact with a person in Germany who has been diagnosed with the virus, the release stated.
Sri Lanka (at least 1 case)
There is one case of the Wuhan coronavirus in Sri Lanka.

Two of the Thai nationals are a married couple who recently traveled to Japan and the other two Thais are "hired car drivers" who have transported Chinese passengers.
Five out of the six cases are in stable condition, but the sixth case -- who is 70 years old and also suffers from tuberculosis -- is in critical condition according to Dr. Wattanayingcharoen.
Thai airports are now screening all Chinese visitors for symptoms. Thai citizens are also being asked to report anyone who seems to have fallen ill after recently traveling from China.

The patients are receiving specialist NHS (National Health Service) care, and we are using tried and tested infection control procedures to prevent further spread of the virus," Chris Whitty said.
"The NHS is extremely well-prepared and used to managing infections and we are already working rapidly to identify any contacts the patients had, to prevent further spread.
"We have been preparing for UK cases of novel coronavirus and we have robust infection control measures in place to respond immediately. We are continuing to work closely with the World Health Organization and the international community as the outbreak in China develops to ensure we are ready for all eventualities."
United States (at least 11 cases)
There are now 11 cases of the novel coronavirus in the United States.
Two cases have been confirmed in San Benito County, California according to a statement provided by San Benito County Public Health Services.
The confirmed cases in San Benito County are related -- the individuals are husband and wife, both 57 years of age, according to the statement. The husband recently traveled from Wuhan, China, and the wife did not -- therefore, there has been person-to-person transmission.
Six confirmed cases are in California, one in Massachusetts, one in Washington state, one in Arizona, and two in Illinois.
The State Department is telling US citizens not to travel to China amid the outbreak. In an advisory posted on the State Department website Friday, the agency elevated its travel warning to "Do Not Travel" and warned of possible "travel restrictions to be put into effect with little or no advance notice."
The advisory said US citizens currently in China should consider leaving using commercial means.
The US Centers for Disease Control and Prevention on Wednesday confirmed that 195 passengers who have been evacuated from Wuhan arrived at March Air Reserve Base in Riverside County, California, Wednesday.
