Assessment of Risk Factors Associated with Malaria Infection Among Adult Populations in Selected Internally Displaced Camps in Goma, North Kivu Province, Dr. Congo

Abstract : Malaria remains a significant public health concern in many parts of the world, particularly in Africa. The Democratic Republic of the Congo (DRC) is one of the countries most heavily affected by malaria, with millions of cases reported annually. In the Eastern region of the DRC, ongoing conflict has resulted in large numbers of people living in precarious conditions within IDP camps, where the risk of malaria transmission is heightened due to unsuitable housing conditions, lack of bed net, overcrowded and unsanitary conditions with limited access to essential healthcare services. This study aims to assess the risk factors associated with malaria infection among adult populations in the Kashaka and Shabindu IDP camps in Goma, North Kivu Province. The study employed a cross-sectional design using a mixed-method approach. Data were collected from 371 households through interviews and medical record reviews. Chi-square tests were performed for bivariate analysis, and then logistic regression to evaluate the impact of multiple variables simultaneously. All participants pointed to mosquitoes as the causal agent. Around 97.8% confirmed that fever is the main symptom followed by chills (75.2%), headache (54.5%), and sweating (10.2%). Bed net was identified as a preventive measure at (100%), mosquito repellents (71.7%), and Indoor residual spraying (68;2%). Approximately 43.9% of households had at least one case of malaria with an increasing incidence in April (26.7%) and October (35.9%). The most significant factors affecting the spread of malaria were gender (OR: 1.73; p-value < 0.001), lack of bed net (OR: 5.231; p-value < 0.001), outdoor activities at night (OR: 0.661; p-value = 0.0364), and being close to sanitation facilities (OR: 2.458; p-value = 0.0013). These underscore the critical need for targeted malaria prevention measures, including increased bed net availability and usage, enhanced sanitation infrastructure, and heightened awareness about the dangers of outdoor nighttime activities.
