Background: Climate change exacerbates infectious disease transmission in Nigeria, a country with a high burden of infectious diseases.
Objective: To conduct a systematic review and meta-analysis examining the relationship between climate variability and infectious disease transmission in Nigeria.
Methods: We systematically searched major databases, identifying 25 studies, with 11 studies meeting the inclusion criteria for meta-analysis using R version 4.4.1.
Results: The meta-analysis revealed significant associations between temperature increases and malaria (pooled effect estimate = 1.034, 95% CI: 1.016-1.052) and Lassa fever (pooled effect estimate = 1.029, 95% CI: 1.015-1.043) transmission. Egger's funnel plot showed no significant publication bias, and sensitivity analysis confirmed the robustness of the findings.
Conclusion: This study provides evidence for the association between climate variability and infectious disease transmission in Nigeria. This underscores the urgent need for targeted interventions to protect vulnerable populations, including children under 5, pregnant women, the elderly, people with comorbidity, and low-income communities.
