Assessing the relationship between armed conflict and infectious disease incidence in Six Sub-Saharan Countries: Implications for Emergency Departments in conflict areas.

Introduction: This study aimed to update and expand on prior ecological analyses by examining within-country and cross-national correlations between conflict deaths and infectious disease incidence in six neighboring sub-Saharan African countries. Methods: We analyzed six countries including Uganda, Rwanda, the Democratic Republic of the Congo, Central African Republic, South Sudan, and Burundi using conflict death data from the Uppsala Conflict Data Program and disease incidence data from the World Health Organization databases. Data were analyzed for the maximum period covered in the UCDP for each country, in general from 1990 to the present. Seven diseases were examined: malaria, tuberculosis, human immunodeficiency virus, tetanus, pertussis, measles, and yellow fever. We assembled matrices of regressions between conflict deaths and disease incidence within and across countries. The approach of this study was hypothesis-generating, with the intent to flag associations worthy of further consideration. Results: Within-country analyses identified strong positive associations in Burundi (e.g., tuberculosis: R² = 0.81, Conclusion: We confirm prior reports of malaria incidence association with armed conflict while introducing potential new associations involving tetanus and measles. Our hypothesis-generating approach supports further research. Emergency physicians and health systems in conflict-affected and adjacent regions should anticipate shifts in disease burden and consider preparedness strategies.
