Occupational Health Governance and Workforce Productivity in Nigeria: Addressing the Burden of Microbial Infections

Abstract

Microbial infections impose substantial burdens on workforce productivity in Nigeria, with profound implications for economic growth, household welfare, and national development. This comprehensive review examines the mechanisms through which infectious diseases affect worker performance, labour supply, and economic output across formal and informal sectors. Drawing on recent epidemiological evidence, occupational health studies, and economic analyses, the findings reveal that prevalent infections including malaria, respiratory tract infections, and antimicrobial-resistant pathogens significantly compromise workforce efficiency. Experimental evidence demonstrates that workplace-based malaria treatment programmes increase worker earnings substantially, underscoring the direct productivity benefits of infection control. Occupational exposure studies among waste handlers reveal that the vast majority of workers experience health-related complaints, with respiratory and skin infections predominating, yet only a small fraction seek hospital care while most resort to self-medication. Antimicrobial resistance threatens to exacerbate these productivity losses, with experts warning of billions in annual economic costs and potential global GDP decline, with Nigeria facing disproportionate impacts. Informal sector workers, constituting the overwhelming majority of Nigeria's workforce, face particular vulnerabilities due to poor working conditions, absence of occupational health protections, and limited access to health insurance. The poverty-disease cycle operates powerfully in working communities, as infection-related productivity losses reduce earnings, limit healthcare access, and perpetuate economic hardship. Policy recommendations emphasise strengthening occupational health regulations, expanding health insurance coverage for informal workers, implementing workplace infection control measures, and investing in antimicrobial stewardship to preserve workforce productivity and advance sustainable development.
