Avian influenza A(H9N2) viruses
Current situation:
Since the last update10, two laboratory-confirmed human cases of A(H9N2) virus infection were reported to WHO from China. No abnormalities were observed among close contacts of these cases at the time of reporting.
In addition, four other cases were identified in China over the past six months, including one retrospectively diagnosed case from 2015. For more details on these cases, see Table 2 below.
The outcome of a previously reported case, a 57-year-old woman with underlying conditions from Sichuan province in China, was recently reported as fatal. This would be the first fatality associated with influenza A(H9N2) virus infections in humans. Avian influenza A(H9N2) viruses are enzootic in poultry in China.
