Chikungunya virus (CHIKV) is primarily associated with non-human-primates (NHPs) in Africa, which also infect humans. Since its introduction to Brazil 2014, CHIKV has predominantly thrived urban cycles, involving Aedes aegypti mosquitoes. Limited knowledge exists regarding occurrence and implications rural sylvatic cycles where neotropical NHPs are potential hosts, from we highlight Leontopithecus chrysomelas (Kuhl, 1820), the golden-headed lion tamarin (GHLT), an endangered species endemic Atlantic Forest (AF) Southern Bahia State, Brazil. The present study investigated wild GHLT groups across two municipalities, Ilhéus Una, Bahia. Surveys were conducted three within cocoa agroforests ( cabrucas ) Ilhéus, four anthropized forest agroforestry fragments between 2021 2022. Thirty-two specimens captured chemically immobilized, examined submitted blood sample collection; nine later recaptured 2022, totaling 41 samples. viremia was not detected any (as assayed by RT-qPCR).

All samples seronegative for Mayaro Virus. Eight mosquito Culicidae family collected, identified genomes, showing negative results. This provides first evidence exposure among free-living GHLTs Brazil, emphasizing their susceptibility role as reservoirs. These findings underscore possible consequences anthropic disturbances Brazilian AF, without seroprevalence difference non-protected formations, agroforest various mosaic farming landscapes South Bahia, importance conservation efforts this primate species.
