Taiwan's health authorities on Saturday reported this year's first case of a human infected by avian influenza (H7N9) and are actively tracking the health of as many as 108 people who came in contact with the patient over the past two weeks.
Beijing on Saturday reported a human H7N9 avian flu case, the first human infection in the capital city in 2017, authorities said.
The Centres for Disease Control (CDC) announced that a Taiwanese businessman in mainland China was confirmed to have been infected with the H7N9 virus several days after returning from the mainland on Jan. 25.
The 69-year-old man, a Kaohsiung native, is now under intensive care and remains unresponsive.
The man developed a fever on Jan. 23 while working in China's Guangdong province and had sought medical treatment there, said Lo Yi-chun, deputy director general of the CDC.
He returned to Taiwan on Jan. 25 and went to a local hospital the following day.
He was suspected to have been infected with avian influenza A. At the hospital, he tested negative for the H7N9 virus, said Lo. But on Jan. 29, the patient showed signs of a fever and coughing with phlegm and went to the hospital again, at which time doctors suspected that he had pneumonia.
