Why this research matters now
The review identified surveillance and early-warning systems, water and sanitation improvements, oral cholera vaccination, community engagement, and climate-informed planning as recommended control strategies. It also identified a need for stronger time-series studies, intervention evaluations, and improved integration of climate and health surveillance data.
Structured evidence summary
Research question
What evidence exists on climate-related drivers of cholera transmission, epidemiological patterns, and control strategies in Nigeria?
Study design
This was a scoping review using the Arksey and O’Malley framework and PRISMA-ScR guidance. The authors searched three databases and reference lists for studies published from January 2000 to November 2024, with independent screening by two reviewers and narrative synthesis.
Population and setting
The review covered studies examining climate–cholera relationships in Nigeria. Thirty-two studies met the inclusion criteria from 187 identified records.
Main findings
Rainfall variability was the most commonly examined climate factor, followed by temperature and flooding. Most included studies reported a positive association between heavy rainfall and cholera outbreaks, while temperature results varied; the rainy season was described as the period of highest reported risk, with peaks commonly occurring from June to August.
Public-health relevance
The review identified surveillance and early-warning systems, water and sanitation improvements, oral cholera vaccination, community engagement, and climate-informed planning as recommended control strategies. It also identified a need for stronger time-series studies, intervention evaluations, and improved integration of climate and health surveillance data.
Important limitations
The review reports inconsistent temperature findings and identifies seasonal confounding between temperature and rainfall as a possible explanation. It also notes gaps in long-term, higher-resolution analyses and evaluations of climate-responsive interventions; this summary is additionally limited to the supplied single-article abstract and metadata and requires the original paper for decision-grade interpretation.
GIDS interpretation
The article is discoverable in the supplied metadata under cholera, climate and environment, surveillance, transmission dynamics, and vaccination, with Nigeria listed as a country context. It provides literature context on reported climate–cholera relationships in Nigeria and should not be interpreted as confirmation of a current surveillance signal.
Related GIDS surveillance
Literature context does not validate, explain, or change a surveillance signal. Exact and contextual relationships are shown separately.
Evidence relationships
This article has 10 auditable classifier relationships to diseases, places, topics, and study design.
