Animal and human health care services could not be well coordinated owing to the lack of integrated preparation and planning. Because the sentinel surveillance of influenza infections in Turkey was based on the confirmation of the cases diagnosed at the training and research hospitals in selected provinces, detection of possible human avian influenza cases at the primary health care level was hindered and trace-back investigation was precluded. To evaluate the spread of the avian influenza outbreak accurately, evaluation and follow-up of influenza cases needs to be done in all health care centers. Such evaluation also necessitates integrated human and animal surveillance and control measures.
