The Arbovirus (ArBoViruses = arthropod-transmitted viruses) represents an ecological grouping based on transmission by arthropods. Arboviruses are biologically transmitted between vertebrates (hosts) and hematophagous arthropods (vector) such as mosquitoes, simulids, sandflies and ticks. Arboviruses have great impact on public health, because causing sporadic and epidemic outbreaks that affect to human and animal populations. Yellow Fever virus is a member of Flavivirus genus, which affects about 200,000 people each year and 30,000 people die each year in unvaccinated populations. During 2016- 2018 an outbreak of Yellow Fever virus (YFV) affect Brazil, producing an alert in the North of Argentina. In this sense, we performed mosquito captures in thenortheast part of Corrientes province during April of 2019, in areas where black and gold howler monkeys (Alouatta caraya) populations were present and where there were reported epizootics from 2009. The objective of the present study was to investigate the circulation of YFV in mosquitoes that could be implicated in the sylvatic transmission of YFV in Argentina. Mosquitoes were captured manually using entomology nets at ground level during day light.
