Abstract：Chikungunya fever is an acute mosquito-borne infectious disease caused by chikungunya virus(CHIKV),characterized by fever,rash,and joint pain.It is widely prevalent in tropical and subtropical regions.Phylogenetic analysis divides CHIKV into three geographically associated genotypes:West African genotype(WAf),East/Central/South African genotype(ECSA),and Asian genotype.At least 16 provinces in China have detected imported cases of chikungunya fever,among which Yunnan,Zhejiang,and Guangdong have also experienced local epidemics caused by imported cases.The cases are mostly imported from Southeast Asia and South Asia,and the incidence has obvious clustering.The epidemic strains are mainly East/Central/South African Indian Ocean evolutionary lineages and Asian genotypes.The laboratory testing of chikungunya fever mainly relies on serological testing and molecular biology testing,and the comprehensive use can improve diagnostic accuracy.Since July 2025,there has been an outbreak of chikungunya fever caused by imported cases in Guangdong Province,China.As of July 22,there were 3 195 confirmed cases.In order to strengthen epidemic prevention and control measures,this article summarizes the diagnostic techniques and control strategies for chikungunya fever,providing reference for epidemic prevention and control.
