Disease Control in Humanitarian Emergencies

Field epidemiology

Setting up early warning surveillance and response systems

Delay in the detection of outbreaks and inadequate preparedness and response aggravates the impact of communicable diseases, leading to increased numbers of cases, increased duration of epidemics, excess mortality and the potential for spread to other areas nationally, regionally, or globally.

Setting up early warning surveillance systems, preparing for, investigating and responding to priority communicable diseases is critical in reducing morbidity and mortality in vulnerable populations affected by humanitarian emergencies, but also in protecting global health security.

Other methods of data collection in humanitarian emergencies such as surveys, as well as monitoring and evaluation of programmes are vital to prioritization and the efficient allocation of resources as well as strengthening interventions.
