Eiji Hinoshita, an official at the ministry's infectious disease section, told reporters that the man told officials he did not go to the fish market in Wuhan linked to the pneumonia outbreak, but had "close contact" with at least one person with pneumonia symptoms at a place where he stayed during the visit. Ministry officials are checking further the patient's activity and people he had contact in China and in Japan since his return, Hinoshita said.
The news just ahead of the lunar new year when many Chinese tourists are expected to travel. The ministry is urging those visiting or returning from Wuhan to wear masks and promptly go to medical institutions if they have cough and fever. But officials said the virus is not considered highly contagious and just passing by or talking to patients would not be a concern.
China has sought to play down speculation that it could be a reappearance of the SARS epidemic, which killed hundreds in 2002 and 2003.
Coronaviruses are a large family of viruses, some of which cause the common cold. Others found in bats, camels and other animals have evolved to cause more severe illnesses.
Common symptoms include a runny nose, headache, cough and fever. Shortness of breath, chills and body aches are associated with more dangerous kinds of coronaviruses, according to the US Centers for Disease Control and Prevention.
