Although the SARS-CoV-2 pandemic primarily affected human population, virus has also been detected in various animal species worldwide, raising concerns about its potential to establish new reservoirs. This study aimed investigate presence of non-human primates (NHPs) and synanthropic small mammals (SSMs) Jequitinhonha Valley Northern Minas Gerais, Brazil. Between October 2021 2023, 119 animals were sampled, 82 NHPs 37 SSMs, across 22 municipalities. A total 342 biological samples-including oral nasal swabs, lungs, livers, spleens, blood, feces-were collected analyzed using RT-qPCR, while serum samples submitted neutralization tests. Despite diversity sampled species, habitats, materials, no evidence infection or specific antibodies was any individuals tested. The results suggest that SSMs these regions did not act as reservoirs for during period. finding is particularly relevant given high synanthropy such Callithrix penicillata (black-tufted marmoset) Rattus rattus (black rat), which frequently interact with populations. Our underscores importance integrating animal, human, environmental health perspectives under a One Health framework monitor emerging zoonotic threats. By providing baseline data on dynamics wildlife, we emphasize need ongoing ecological epidemiological surveillance assess spillover events their implications biodiversity public
