Resumo: The simultaneous transmission of chikungunya virus (CHIKV) - dengue viruses (DENV) has been a major public health concern because of their sympatric distribution - shared mosquito vectors. Groups of Aedes aegypti (L.) - Aedes albopictus (Skuse) were orally infected with 1.5 × 10(5) PFU/ml of CHIKV - 3.2 × 10(6) FFU/ml of DENV-2 simultaneously or separately in inverse orders - evaluated for dissemination - transmission by qRT-PCR. Simultaneous dissemination of both viruses was detected for all groups in Ae. aegypti - Ae. albopictus while cotransmission of CHIKV - DENV-2 only occurred at low rates after sequential but not simultaneous infection.
