AI Insight
This scoping review analyzed 10 studies examining how climate-related stressors and infectious diseases interact to affect worker health across healthcare, agriculture, construction, and emergency response sectors. The research found that these combined hazards disproportionately impact vulnerable populations including migrant workers, informal laborers, and low-income groups, while current policy responses remain fragmented and address climate and infection risks separately. The evidence base consists primarily of descriptive and qualitative studies with limited longitudinal or predictive modeling approaches.
Why it matters
The findings reveal critical gaps in occupational health protections during compound crises and suggest that integrated multi-hazard strategies combining climate adaptation, infection prevention, and psychosocial support could strengthen workforce resilience. This is particularly relevant for protecting vulnerable worker populations who face overlapping environmental and health risks but have limited access to healthcare and legal protections.

Objective
This scoping review examines how climate-related stressors and infectious-disease conditions, including pandemic-related workplace disruptions, interact to influence worker health, vulnerability, and occupational resilience. The review focuses on shared exposure pathways, vulnerable worker populations, methodological patterns, policy gaps, and strategies for strengthening worker safety under compound hazards. Rather than treating pandemics as isolated events, the review uses pandemic conditions as a lens to understand broader, recurring occupational risks and to inform strategies for building safer and more resilient workplaces under compound hazards.
Methods
Following PRISMA-ScR guidelines, a structured literature search was conducted in PubMed, Scopus, Web of Science, and Google Scholar for English-language peer-reviewed and formally structured evidence sources published primarily between January 2020 and April 2025, with one pre-2020 policy study retained for foundational context. Out of 612 records initially identified, 10 studies or sources met the inclusion criteria across healthcare, agriculture, construction, emergency response, and other high-exposure sectors after systematic screening and eligibility assessment. Data were charted and synthesized by occupational sector, geographic region, exposure type, worker vulnerability, and methodological approach.
Results
The evidence indicates that climate-related and infectious-disease stressors frequently converge, amplifying physical, environmental, and psychosocial pressures on workers. Disproportionate risks were observed among migrant workers, informal laborers, low-income populations, older adults, women, and seasonal or cross-border agricultural workers, particularly where access to healthcare, legal protections, or adaptive infrastructure was limited. Most studies relied on descriptive, qualitative, cross-sectional, conceptual, or review-based designs, with limited use of predictive modeling, geospatial analysis, longitudinal evidence, or integrated datasets. Policy responses were often fragmented, with climate adaptation and infection-control measures addressed separately despite overlapping benefits.
Conclusions
Climate-related and infectious-disease stressors interact to reinforce occupational health inequities and expose persistent gaps in worker protection. The findings highlight the need for integrated, multi-hazard occupational health strategies that align climate adaptation, infection prevention, and psychosocial support. Embedding data-driven early-warning systems, equitable protections for vulnerable workers, and cross-sector coordination into occupational policies may help strengthen workforce resilience during routine operations as well as future climate extremes and public health crises. However, the findings should be interpreted with caution because of the limited number of available studies combining climate-related and infectious-disease occupational risks, heterogeneous study designs, and the emerging nature of the evidence base. Furthermore, since this scoping review maps evidence rather than formally grading evidence strength or testing causal relationships, recommendations should be interpreted as evidence-informed directions for future occupational-health planning and research.
