Resumo: We report results of the entomo-virological surveillance system in Aedes aegypti local populations performed by the Ministry of Health of Guerrero. Indoor-adult Ae. aegypti collected at Acapulco, Zihuatanejo, Coyuca de Benitez - Atoyac de Alvarez (dry season, 2015) were processed for dengue virus (DENV) - chikungunya virus (CHIKV) using RT-PCR. We identified different seroptypes of DENV (2, 3 - 4), CHIKV - their co-circulation in field-caught mosquitoes across a significant geographic area. Pools of males were positive for CHIKV - DENV 3 - 4 suggesting vertical transmission. Entomo-virological surveillance in Guerrero has identified early circulation of CHIKV - DENV - provided a trigger for timely - focalized vector control actions.
