China: Avian Flu Stirring





For nearly a year now, getting timely information out of China on human avian flu infections has been nearly impossible, with most provinces only providing a summary total buried in a spreadsheet submitted with their EOM epidemiological report.  


A few provinces (Guangdong in particular) have continued to post official notices, and we’ll see an occasional media report, but for the most part we only hear about cases weeks or months after the fact. 


Today Sharon Sanders of FluTrackers has picked up the latest such summary (see  China - NHFPC announces 2 bird flu cases (excluding H7N9) and 1 death for November 2015 - H5N1, H5N6, H10N8 ?) which lists 2 `Bird Flu Cases’ and 2 H7N9 cases in November.

Although avian flu doesn’t rate a mention in the text summary, there are two entries buried among the 42 other infectious diseases included in the attached annex.   No details regarding subtypes, locations, or epidemiology are included.

Equally vague, but indicative of increasing activity, is the following news item (repeated across several media streams) indicating additional avian flu cases in Zhejiang province.   Exactly when, where, and how many cases, is less than clear.
