Resurgent threat in a changing climate: A 20-year bibliometric analysis of global Chikungunya research evolution and pandemic preparedness.
Article in PLoS neglected tropical diseases, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundDriven by climate change and urbanization, chikungunya virus (CHIKV) has evolved from being a localized pathogen to being a global pandemic threat. This bibliometric analysis maps 20 years (2004-2025) of global CHIKV research to identify priorities and gaps in pandemic preparedness.
methodsWe analyzed 8,125 publications from the Web of Science using bibliometrix (R) and VOSviewer, examining output trends, collaboration networks, thematic evolution (keyword co-occurrence), and alignment with containment needs.
resultsAnnual publications surged 7-fold after 2013, peaking during epidemics (e.g., Caribbean 2013-2014, Réunion 2024). Research was dominated by the USA, Brazil, France, and India, which formed distinct regional hubs. Thematic clusters revealed rising priorities: vaccine development (proportional growth: +7.1% during 2020-2025; candidates such as VLA1553 emerged) and climate-driven transmission ("environmental health" became central after 2022). Persistent gaps included diagnostic overlap with dengue/Zika and reactive outbreak responses (emergency-focused keywords, e.g., "emergency response and crisis management", declined from 15.5% to 7.2%). International collaborations favored high-income/endemic nations, with limited equity.
conclusionWhile CHIKV research increasingly addresses vaccines and climate drivers, critical weaknesses remain in terms of equitable collaboration, climate-adaptive surveillance, and integrated interventions. We advocate for predictive modeling, rapid-response vaccine platforms, and embedding CHIKV preparedness within climate-resilient health policies to transform reactive efforts into sustained pandemic resilience.
