Epidemiological characteristics and transmission dynamics of the early stage Chikungunya fever outbreak in Foshan City, Guangdong Province, China in 2025.

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
backgroundAs of July 22, 2025, the chikungunya virus transmission has been documented across 119 countries and territories of the world. In 2025, an outbreak of chikungunya fever (CF) occurred in Foshan, Guangdong Province, China. We aimed to analyze the epidemiological characteristics and transmission dynamics during the early stage of this outbreak.
methodsWe collected the data of CF cases in Foshan from July 8 to July 26, 2025. Case data were extracted from the National Notifiable Infectious Disease Reporting System. Demographics and tempo-spatial distributions of cases, incidence rates and the onset-to-report interval times were analyzed. Global spatial autocorrelation (Moran's I) to assess township-level clustering; Kruskal-Wallis tests with Dunn's post-hoc comparisons (Bonferroni-corrected) to analyze onset-to-report intervals across four epidemic phases. The basic reproduction number (R
resultsA total of 4,754 local cases were reported during the study period. Persons aged 65 years or above had the highest incidence (116.57 per 100,000 population). Most cases were business/service workers, homemakers, and retirees. The median onset-to-report interval decreased from 4 days to 1 day after outbreak control measures were implemented. The outbreak, initially detected in Shunde District, spread rapidly to other districts of Foshan, forming a significant spatial cluster (Moran's I = 0.152, P = 0.029). The estimated R
conclusionsThis outbreak was characterized by high transmissibility, with older persons being a primary high-risk group. The rapid reduction in case reporting delay highlights the effectiveness of response interventions. Sustained, integrated and prompt response has been essential to control the outbreak.
