Comment: based on previous years' observations, an increase in reported H5N1 influenza events in poultry is expected for this time of year. Sporadic human cases reported this month [December 2012] in countries with known influenza A(H5N1) virus activity in poultry are within the expected range. No onward sustained human to human transmission was reported.

Public health risk assessment of avian influenza A(H5N1) viruses: the public health risk remains unchanged.
