The health ministry said Saturday it has confirmed a third case of a new deadly virus that has been rapidly spreading in China and beyond.
The patient is a woman from the central Chinese city of Wuhan, where the outbreak of the mysterious coronavirus began, the ministry said, adding she arrived in Japan on Jan. 18.
The ministry has not disclosed her nationality and from where she entered Japan.
The woman in her 30s, who is in stable condition, is said to have had no symptoms at the time of arrival but developed a fever and started coughing on Tuesday night, according to the ministry.
She visited a Tokyo hospital on Thursday and later tested positive for the virus, which has killed at least 41 people in China.
The number of people with pneumonia caused by the virus topped 1,300 worldwide on Saturday, just as hundreds of millions of Chinese citizens set out on domestic and overseas trips at the start of the Lunar New Year holiday.
