The World Health Organization has posted a list of 11 recent H7N9 cases reported to them by the Chinese government as of December 16th.  Of particular note: All 11 had onset dates between November 14th and December 1st, 8 of the 11 are male, and the youngest patient was 27.


While there are open questions regarding the actual incidence of mild, or even asymptomatic infection, among those sick enough to be hospitalized (and therefore tested), cases are continue to run overwhelmingly male and older.
