Infectious Disease Burden in the Aftermath of War: Insights from Historical and Contemporary Perspectives

Abstract

Introduction: Armed conflicts have long been catalysts for infectious disease outbreaks, from typhus during the Napoleonic wars to cholera in modern-day Yemen. These outbreaks are often driven by mass displacement, the collapse of health systems, and the breakdown of sanitation infrastructure. Methods: This minireview examined literature from 1800 to 2023 to explore the link between   armed conflict and infectious disease outbreaks. Using sources like PubMed, JSTOR, WHO, and ICRC reports, the study focused on major conflicts with significant epidemiological impact and reliable disease data. It analysed the types of diseases reported, contributing factors (such as displacement and health system collapse), and public health responses. The aim was to identify recurring patterns and insights to guide future humanitarian and health strategies in conflict zones. Results: Outbreaks of cholera, malaria, tuberculosis, and typhus were consistently reported during and after major conflicts. Common contributing factors included healthcare system disruption, population displacement, interrupted vaccination programs, and ecological changes. Recent conflicts in Syria, Yemen, Tigray, Myanmar, and Gaza demonstrate similar epidemiological patterns, despite advances in medical technology. Conclusion: Infectious disease outbreaks are a predictable and recurring consequence of armed conflict. Strengthening health system resilience, enhancing early disease surveillance, and ensuring humanitarian access must be prioritized in modern conflict response strategies.
