Avian Influenza in Humans

China (LPAI H7N9). Chinese health officials confirmed an outbreak of H7N9 in the Anhui province on April 29. The victim, a 55-year-old man from Lu’an city, was hospitalized on April 26. His current condition is unknown at this time. This most recent outbreak brings the total number of H7N9 cases to 433 within the last year.

Taiwan (LPAI H7N9 ex China). Taiwan’s Centers for Disease Control (CDC) confirmed on April 25 the fourth imported case of H7N9 avian flu since last April. The victim, a 39-year-old Taiwanese man, had recently visited Beijing and Jiangsu province, and showed flu-like symptoms after returning back to the island. He is currently being treated in an intensive care unit and no one that he has had close contact with have shown symptoms of the virus.

Spanish flu (H1N1) research. A new study led by the University of Arizona may answer the question as to why the 1918 flu pandemic killed so many young adults. Their studies show that “a human H1 virus that had been circulating among humans since around 1900 picked up genetic material from a bird flu virus just before 1918 and this became the deadly pandemic strain.” Additionally, this research may help “explain differences in patterns of mortality between seasonal flu and the deadly H5N1 and H7N9 bird flu viruses.” More information about this study can be found in the Proceedings of the National Academy of Science.
