Three new laboratory-confirmed human cases of avian influenza A(H5N1) virus infection were reported to the World Health Organization (WHO).
A 2-year-old male resident of Cairo Governorate, Egypt, had onset of influenza-like illness (ILI) symptoms on 30 May 2016, and a sample collected as part of ILI surveillance tested positive for influenza A(H5N1). The case was hospitalized, treated with antivirals for pneumonia and recovered. Prior to his illness, the case had visited a family member who raised birds.
In addition, a 30-year-old woman from Menia Governorate had onset of illness on 11 June and an 8- year-old girl from Cairo Governorate had onset of illness on 18 June. Both cases had exposure to poultry or poultry-related environments prior to illness, were hospitalized with pneumonia, received antiviral therapy and have recovered.
Investigation and follow up of contacts of the three cases took place for 14 days with no further cases reported. Avian influenza A(H5N1) viruses are enzootic in poultry in Egypt.
Since 2003, a total of 854 laboratory-confirmed cases of human infection with avian influenza A(H5N1) virus, including 450 deaths, have been reported to WHO from 16 countries.
