Operational Preventive Medicine (PMT 110) Practice Test

Disease surveillance is the essential preventive medicine activity in refugee settings because it provides the ongoing collection, analysis, and interpretation of health data needed to detect outbreaks early, monitor trends, and trigger timely public health actions. When crowds, displacement, and variable living conditions converge, having a reliable surveillance system allows health teams to see what’s happening, where it’s happening, and how severe it is, so interventions can be targeted and evaluated for impact. While medical staffing, vaccination campaigns, and facility construction are important components of a comprehensive response, they depend on accurate surveillance to guide when and where to deploy resources and to assess the effectiveness of measures.
