The simultaneous transmission of chikungunya virus (CHIKV) and dengue viruses (DENV) has been a major public health concern because of their sympatric distribution and shared mosquito vectors. Groups of Aedes aegypti (L.) and Aedes albopictus (Skuse) were orally infected with 1.5 × 10(5) PFU/ml of CHIKV and 3.2 × 10(6) FFU/ml of DENV-2 simultaneously or separately in inverse orders and evaluated for dissemination and transmission by qRT-PCR. Simultaneous dissemination of both viruses was detected for all groups in Ae. aegypti and Ae. albopictus while cotransmission of CHIKV and DENV-2 only occurred at low rates after sequential but not simultaneous infection.
由于基孔肯雅病毒(CHIKV)和登革病毒(DENV)的同域分布以及共享蚊媒,它们的同时传播一直是一个主要的公共卫生问题。埃及伊蚊(Aedes aegypti (L.))和白纹伊蚊(Aedes albopictus (Skuse))群体分别以1.5×10⁵ PFU/ml的CHIKV和3.2×10⁶ FFU/ml的DENV-2同时或按相反顺序分别经口感染,并通过qRT-PCR评估其传播和扩散情况。在埃及伊蚊和白纹伊蚊的所有群体中均检测到两种病毒的同时传播,而CHIKV和DENV-2的共同传播仅在顺序感染而非同时感染后以低发生率出现。
