Administrative and Policy Dimensions of Microbial Infections in Nigeria’s Public Health System

Abstract

Microbial infections remain a significant public health challenge in Nigeria, imposing substantial burdens on an already strained health system and impeding progress toward universal health coverage. This comprehensive analysis examines the complex interplay between microbial infections and developmental challenges within Nigerian public health systems. Drawing on recent epidemiological data and health systems research, the study reveals that Nigeria faces a quadruple burden of persistent communicable diseases, emerging and re-emerging infections, antimicrobial resistance, and health system deficiencies. Key findings indicate that zoonotic infections affect approximately one-third of at-risk populations, antimicrobial resistance imposes costs equivalent to 2.4% of GDP, and about 80% of public health infrastructure remains dysfunctional. The COVID-19 pandemic has further exacerbated existing vulnerabilities, as evidenced by the resurgence of vaccine-preventable diseases including a diphtheria outbreak affecting over 18,000 individuals. Through analysis of health infrastructure, workforce capacity, surveillance systems, and financing mechanisms, this study identifies critical intervention points for strengthening health system resilience. The findings underscore the imperative of adopting One Health approaches, strengthening primary healthcare, and implementing sustainable health financing reforms to address the developmental challenges posed by microbial infections in Nigeria.
