The number of H5N1 fatalities = 280; the number of H5N1 survivors = 151; the number of H7N9 fatalities = 265; and the of H7N9 survivors = 391. (A) Days from illness onset to laboratory confirmation of influenza A H7N9 or H5N1 virus fatalities and survivors. (B) Days from illness onset to antiviral treatment of influenza A H7N9 or H5N1 virus fatalities and survivors. (C) Days from illness onset to final outcome of infection (fatality or survival) with influenza A H7N9 or H5N1 viruses. (D) Days of hospitalization for A H7N9 or H5N1 fatalities and survivors. (E) Days from illness onset to hospitalization for A H7N9 or H5N1 fatalities and survivors.
