Abstract: In the last decade, Flaviviruses such as yellow fever (YFV) and Zika (ZIKV) have expanded their transmission areas. These viruses originated in Africa, where they exhibit both sylvatic and interhuman transmission cycles. In Brazil, the risk of YFV urbanization has grown, with the sylvatic transmission approaching the most densely populated metropolis, while concern about ZIKV spillback to a sylvatic cycle has risen. To investigate these health threats, we carried out extensive collections and arbovirus screeni… Show more

“…Recently, some of these same monkey and mosquito species have been shown to be susceptible to experimental infection with ZIKV 10 13 , and ZIKV has been isolated from monkeys in suburban neighborhoods in Brazil 14 , 15 . However, the virus has not been isolated from free-living forest mosquitoes, although at present, only low-numbers of the most likely sylvatic vector species have been screened 16 , 17 .…”

“…5 , 6 Thus, human infections in this outbreak were typically acquired in the zoonotic sylvatic transmission cycle where non-human primates (NHPs) are the amplification vertebrate hosts and Haemagogus and Sabethes mosquitoes the primary and secondary vectors, respectively. 1 , 7 , 8 …”

“…The low infection rates in people, although likely to be a gross underestimate [ 62 ], suggest low infection rates in mosquitoes, decreasing the chances of arboviral detection in them. It would also mean fewer opportunities for infected urban mosquitoes to feed on peridomestic AGMs (‘spillback’ infection from people to NHPs) and in the process provide a source of virus for a sylvatic cycle as has been similarly investigated in Brazil [ 63 67 ].…”
