Influenza A (H10N8) virus, the new kid on the block...

Step by step we seem to be getting familiar with the entire influenza spectrum of naming combinations and permutations. When you consider that even 2 influenza viruses with the same common naming scheme (like H7N9) may have completely different evolutionary histories and clinical impact, well, influenza is a tough act to follow epidemiologically.

The latest, called H10N8 was detected in a human (73-year old female) for the first time Dec-6th. H10N8 has been found in the environment in the past.

The woman, who had visited a live bird market, died from respiratory failure following pneumonia, although whether that was due to H10N8 infection is not clear. The woman was treated in hospital in Nanchang, Jiangxi province from Nov-30; she also suffered a heart attack, was immunocompromised, had high blood pressure and a neuromuscular disorder.

Hong Kong's Centre for Health Protection (CHP) urged travellers to stay away from live bird markets and to avoid contact with the birds/poultry and droppings.


As CIDRAP noted, low pathogenicity avian influenza A(H10N7) virus has been reported in 2 Australian adults processing chickens during an outbreak of the virus in 2010 and reported in 2 Egyptian infants (1-year old) possibly linked to market ducks during late April 2004.
