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

ABSTRACT:

Background

As 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.

Methods

We 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 comparison
