Detection of Zika virus in Aedes mosquitoes from Mexico

Trans R Soc Trop Med Hyg. 2017 Jul 1;111(7):328-331. doi: 10.1093/trstmh/trx056.

Abstract

Background: We report on the results of an entomovirological surveillance system of Aedes populations performed by the Ministry of Health of the central state of San Luis Potosí, Mexico.

Methods: Indoor adult Aedes aegypti and Aedes albopictus pools collected at San Martín, Tamazunchale, Ciudad Valles, Metlapa, Ebano, Tamuin and Axtla during the dry season of 2016 were examined for the presence of dengue (DENV), chikungunya (CHIKV) and Zika (ZIKV) viruses using real-time PCR.

Results: Both Ae. aegypti and Ae. albopictus were found to be infected with ZIKV in the absence of confirmed symptomatic human cases.

Conclusions: The entomovirological surveillance system analysed here identified both Ae. aegypti and Ae. albopictus infected with ZIKV which triggered an immediate aggressive vector control campaign.

Keywords: Aedes aegypti; Aedes albopictus; Dengue; Mexico; Surveillance; ZIKV.
