The Taiwan Centers for Disease Control (CDC) announced on April 2, 2026, the detection of the nation’s first indigenous human case of H7 subtype avian influenza. The patient, a male in his 70s residing in central Taiwan, is a poultry farmer with a history of chronic medical conditions.
According to official reports, the patient began experiencing respiratory symptoms, including a runny nose, cough, and myalgia, on March 20. Following the onset of a fever on March 22, he was hospitalized and diagnosed with pneumonia. Subsequent genetic sequencing confirmed the presence of an H7N7 influenza A virus belonging to the Eurasian lineage. Notably, this strain is distinct from the H7N9 virus that caused significant outbreaks in mainland China between 2013 and 2019; instead, it closely matches low-pathogenic avian influenza viruses previously monitored in Taiwan’s wild bird populations.
Contact tracing identified 33 individuals who had been in close proximity to the patient. While all six family members have tested negative for the virus, three other contacts have been placed on prophylactic medication as a precautionary measure. Furthermore, inspections at the patient’s poultry farm have thus far yielded negative results for the virus.
