Risk factors to increase morbidity and mortality include breakdown of health services, movement to new ecological zones, malnutrition, and crowding and poor sanitation in relief camps. Highest mortalities are recorded in children below 5 years, the principal causes being measles, gastro-enteritis, chest infections and malaria. The greatest morbidity and mortality occurs after arrival in relief camps, and could be reduced by epidemiologicaly based, selective health programs.-from Authors
