Objective To investigate the prevalence of zika virus (ZIKV), dengue virus (DENV) and chikungunya virus (CHIKV) infections in blood donors in Kunming, China. Methods A total of 10 662 samples from blood donors in Kunming from August 2022 to October 2023 were randomly collected, and ZIKV RNA, DENV RNA and CHIKV RNA were detected by real-time fluorescence quantitative reverse transcription polymerase chain reaction(RT-qPCR). Results Effective test results were obtained from 10 554 samples, and no positive case of ZIKV RNA, DENV RNA and CHIKV RNA was found in this investigation. Conclusion The risk of ZIKV, DENV and CHIKV infections among blood donors in Kunming is low, and there is no immediate need for routine screening for these viruses among blood donors in this region.
