Detection of Zika Virus in Aedes aegypti and Aedes albopictus Mosquitoes Collected in Urban Forest Fragments in the Brazilian Amazon

Abstract: Zika virus (ZIKV) is an RNA flavivirus (Flaviviridae family) endemic in tropical and subtropical regions that is transmitted to humans by Aedes (Stegomyia) species mosquitoes. The two main urban vectors of ZIKV are Aedes aegypti and Aedes albopictus, which can be found throughout Brazil. This study investigated ZIKV infection in mosquito species sampled from urban forest fragments in Manaus (Brazilian Amazon). A total of 905 non-engorged female Ae. aegypti (22 specimens) and Ae. albopictus (883 specimens) were… Show more

“…In addition to JE vectors, filariasis vectors such as M. annulifera, M. indiana, and M. uniformis (Rojanapanus et al 2019), along with A. albopictus-a known vector for chikungunya and Zika (Vega-Rúa et al 2022;Gomes et al 2023) were detected in the area, albeit at relatively low prevalences. Our study found a limited number of Aedes mosquitoes, including the absence of A. aegypti, the primary vector for dengue.…”

“…Brazil continues to see human cases, including some acute ZIKV disease, suggesting that the virus continues to have low-level circulation 11 . However, the full picture of ZIKV's maintenance and circulation in Brazil remains to be elucidated as non-human primate and mosquito surveillance has sometimes shown discordant results (i.e., evidence of Zika infection or maintenance in either non-human primates or mosquitos, but not both populations in the same time or space) and is largely incomplete in many states [12][13][14] . More research is needed to explain ZIKV's maintenance and circulation across many geographical regions.…”
