Brain Drain can also be defined as an emigration of trained and talented individuals from other nations or jurisdictions, due to conflict, lack of opportunity or health hazards where they are currently working and living. Few countries in the world are unaffected by brain drain of healthcare staff as destination or source countries.  Destination countries receive net flows of professionals while source countries lose their professionals, and as we will see in acute Brain Drain in Iraq, at a precipitous cost to the Public Health of Iraqis.
