Abstract

Objectives

Our study targets the potential of the local urban mosquito Aedes aegypti to experimentally transmit chikungunya virus (CHIKV), dengue virus (DENV), yellow fever virus (YFV), and Zika virus (ZIKV).

Methods

We collected eggs and adults of Ae. aegypti in Medellín, Colombia (from February to March 2020) for mosquito experimental infections with DENV, CHIKV, YFV and ZIKV and viral detection using the BioMark Dynamic arrays system.

Results

We show that Ae. aegypti from Medellín was more prone to become infected, to disseminate and transmit CHIKV and ZIKV than DENV and YFV.

Conclusions

Thus, in Colombia, chikungunya is the most serious threat to public health based on our vector competence data.

哥伦比亚埃及伊蚊造成的城市虫媒病毒疾病威胁加剧

目的我们的研究针对当地城市埃及伊蚊实验性传播基孔肯雅病毒（CHIKV）、登革热病毒（DENV）、黄热病病毒（YFV）和寨卡病毒（ZIKV）的潜力。方法我们在哥伦比亚麦德林（2020 年 2 月至 3 月）收集了埃及蚁的卵和成虫，用 DENV、CHIKV、YFV 和 ZIKV 进行蚊子实验感染，并使用 BioMark 动态阵列系统进行病毒检测。结果我们发现，与 DENV 和 YFV 相比，麦德林的埃及蝇更容易感染、传播和传播 CHIKV 和 ZIKV。
