The objective was to assess the risk factors of arbovirus outbreaks, including vector-borne infection status within representative regions of the country. Aedes aegypti mosquitoes were collected at the larval stage from their natural rearing habitats in four study sites when estimating the main larval index, then reared until adult stage and kept in RNAlater for the detection of arbovirus RNA. In the laboratory, mosquito samples were tested for dengue virus (DENV) and Chikungunya virus (CHIKV) using a real-time qRT-PCR stage. A DENV-2 positive pool was detected in Ouagadougou with a minimum infection rate (MIR) of 16.67 and other six CHIKV-positive pools with a MIR of 66.67 in Ouagadougou, Banfora, and Boromo. This qRT-PCR approach, if validated with various samples also comprising wild blood-fed adults, is a useful tool for arbovirus circulation and disease monitoring in Burkina Faso. specialized BURKINA FASO OUAGADOUGOU 052 050 3 920224 [10 ] 2022 2673-7515 https://www.documentation.ird.fr/hor/fdi:010093321 10.3389/fitd.2022.920224 2673-7515 [F B010093321] https://www.documentation.ird.fr/hor/fdi:010093321 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2025-05/010093321.pdf IRD - Base Horizon / Pleins textes 2025-04-07 2025-05-16 fdi:010093321 fre
