AbstractBackgroundOn March 4, 2012, an arms dump exploded in a densely populated area in Brazzaville, Republic of the Congo. At least 250 people were killed, 2,500 wounded, and 13,800 left homeless, of which 5,000 were relocated to a newly constructed internally displaced person (IDP) camp.AimTo describe the medical complaints of persons presenting to the IDP camp for medical evaluation.Patients and MethodsAll patients seen and treated by the Belgian First Aid and Support Team (B-FAST) in the IDP camp on March 10 and 11, 2012 were included. A unique number, age, gender, and inventory of complaints were registered on standard World Health Organization (WHO) forms.ResultsOut of 245 presenting patients, 242 files were processed. One in two patients were minors (<18 years-old), the male/female ratio was 50/50 in minors and 28/72 in adults; median (range) age in minors was three years (0-17) and for adults was 32.5 years (18-68). Twenty percent of the children were determined to be malnourished. Signs and symptoms related to infectious diseases were present in 75% of minors and 53% of adults. Trauma was present in 12% of minors and 21% of adults.ConclusionsOne week following the disaster event, after people had relocated to IDP camps, infectious diseases became the predominate reason for seeking medical evaluation. Less than one in five people presenting to the medical post had injuries directly related to the event. Demographic data showed that around 50% of people in the IDP camp presenting for medical care were children, of which one in five was malnourished.RoggenI,van BerlaerG,GijsG,HubloueI.Clinical characteristics of the inhabitants of an internally displaced persons camp in Brazzaville, Republic of Congo after the arms dump blast on March 4, 2012.Prehosp Disaster Med.2014;29(5):1-5.
