Impact of climate change on the global circulation of chikungunya virus: current evidence, future projections, and adaptation strategies.
Review in Infectious diseases of poverty, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundClimate change is accelerating the circulation of the chikungunya virus (CHIKV), posing a significant threat to both endemic areas and immunologically naive temperate regions. This study aims to synthesize empirical climatic drivers, future transmission projections, and global adaptation strategies to evaluate current evidence and identify key research gaps.
methodsThis scoping review completed protocol registration on the Open Science Framework prior to literature retrieval, with systematic searches conducted across PubMed, Web of Science, Scopus and EBSCOhost to collect all relevant English peer-reviewed papers published between Jan 1, 2000 and Nov 1, 2025. Multi-level screening filtered out unqualified literature, and unified datasets related to epidemiological parameters, predictive models and adaptation measures were extracted from 104 eligible studies.
resultsThe results indicate that: (1) Current evidence reveals post-2014 research favors Europe and South America, disproportionately focusing on temperature (n = 38) and precipitation (n = 32). CHIKV transmission exhibits a non-linear thermal optimum (23-30 °C) and a 1-to-4-week lag following extreme precipitation. (2) Future projections (n = 24) consistently indicate transboundary vector expansion into higher latitudes and altitudes. (3) Regarding adaptation strategies, we conceptualized a three-tiered intervention framework. However, a stark socioeconomic-climatic gap emerged: while 43% of the research centers on mid-tier early warning systems in high and upper-middle-income nations, evidence for the foundational infrastructural resilience in low-income regions is limited.
conclusionThis global climate-CHIKV synthesis reveals structurally imbalanced preparedness. To mitigate escalating transboundary risks, international health policies must pivot from solely reactive surveillance. Future priorities should include proactive, climate-resilient urban infrastructure and equitable cross-border coalitions in neglected low-resource settings.
