Increased risk of epidemics - With over 65% of outbreaks of international importance originating in conflict settings. Increased duration of epidemics - Due to delays in detection, poor access to healthcare and drugs. Rapid emergence of drug resistance - Due to disruption of treatment and poor compliance and the use of outdated or inappropriate drugs regimens. Emerging diseases (Marburg & Ebola) and eradication projects (Guinea Worm & polio) both pose their own threats.
