A man who travelled to Japan from Wuhan, China was infected with a mysterious pneumonia-causing virus
The Japan Times reported that the man is a Chinese national who lives in the Kanagawa prefecture. He developed a fever on 3 January during his visit to Wuhan and he returned to Japan three days later.
In a statement by the Japan Ministry of Health, Labour, and Welfare, they explained that he was hospitalised last Friday, 10 January but was discharged on Wednesday after his condition improved.
Similar to another case in Thailand, the man had not visited the now-closed seafood market associated with the outbreak
It is possible that he came in close contact with a person infected with the virus while in Wuhan, the ministry said.
Initially, authorities linked the mysterious illness to the Huanan Seafood Wholesale Market where some of the viral pneumonia cases originated.
However, these new cases have raised the possibility that the pathogen is lurking more widely in the city. This is a pressing matter as the city of Wuhan is expected to be bustling with people visiting markets to prepare for Chinese New Year.
According to The Straits Times, the outbreak in China has hospitalised dozens of people, killing one.
