ReviewInfection2026
Epidemiological and molecular analysis of the Chikungunya virus outbreak in the state of Rondônia.
Review in Infection, 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
purposeThe Chikungunya virus (CHIKV) is an arbovirus transmitted by hematophagous arthropods, widely distributed in tropical and subtropical regionsAQ1. In Brazil, its introduction in 2014 marked the beginning of a significant expansion, becoming a major public health problem.
methodsThis work consists of a cross-sectional study conducted from October 2024 to July 2025, in which 830 samples from patients with acute febrile illness and negative diagnosis for malaria were evaluatedAQ2. The samples were tested for dengue, Zika, and chikungunya and subjected to duplex RT-qPCR to detect Mayaro and Oropouche.
resultsOf the samples analyzed, 5,18% (43/830) tested positive for some arbovirus investigated in this cohort, of which 53,49% (23/43) were detectable for CHIKV. The phylogenetic analysis showed that all samples belonged to the East/Central/South African (ECSA) genotype, demonstrating its circulation in the region.
conclusionsThe findings reinforce the need for continuous molecular surveillance to monitor the circulation of medically important arboviruses in the Amazon region.
