The ecological factors contributing to the chikungunya outbreak in Ruili, a border city in Yunnan Province, China.

ABSTRACT:

Background

Chikungunya virus (CHIKV), an arthropod-borne pathogen, has caused recurrent epidemics in tropical and subtropical regions, as well as sporadic outbreaks in certain temperate areas, posing significant public health challenges. The globalization-driven increase in international tourism and trade has facilitated the spread of the virus, leading to several outbreak events in China triggered by imported cases, including the 2019 outbreak in Ruili City, Yunnan Province.

Methods

This study conducts a quantitative analysis of the spatiotemporal patterns of outbreak in Ruili City and investigates the impact of ecological factors on the occurrence of local chikungunya cases and the extent of its autochthonous transmission, using panel logistic regression and Poisson regres
