After late December's announcement of a human infection with another avian influenza subtype, H5N6. The tally of human infections by this subtype of FluA stands at 2 - that are reported anyway.

The ever vigilant @FluTrackers (and their line lists, news posts and commentary) and the always alert @Fla_Medic (and his Avian Flu Diary blog) have these cases well covered.

I just wanted to make a summary here for my own reference in making some slides for a talk next month.
  1. ~23-April-2014. [1,4,5] 49-year old male (49M) from Nanchong City, Sichuan Province.
    Acute severe pneumonia, died 5-May-2014
    Exposed to dead poultry
  2. 3-December 2014. [2] 58M from Guangzhou City in Guangdong province.
    Critical condition in hospital since 9-Dec-2014
    Exposed to live poultry but not ill contacts [3]
There have also been plenty of lethal animal infections by this and other highly pathogenic avian influenza (HPAI; referring specifically to the bird's outcome) subtypes and strains [7], including:

No sign of anything like sustained human-to-human transmission of this viral subtype to date. But another for the influenza virus Rubik's cube.
