Those cases followed a report on Jan 7, also from the WHO, of another laboratory-confirmed case of human infection from H7N9, reported by Taipei Centers for Disease Control. That case, which was initially reported to the WHO on Dec 31, 2013, was in an 86-year-old man from Jiangsu, China who traveled to Taiwan with a tourist group from Dec 17-24.
The man felt uncomfortable on Dec 19, but was not admitted until Dec 24 after being diagnosed with bilateral pneumonia and acute respiratory distress syndrome. As of Jan 7, the man is currently intubated and supported by extracorporeal membrane oxygenation. The other members of the group returned home with no symptoms; the man’s two daughters remained in Taiwan but have also shown no symptoms.
