Fatal yellow fever among captive non-human primates in southern Colombia, 2025.

ABSTRACT:

Background

Yellow fever virus (YFV) remains a re-emerging zoonotic threat in South America. While epizootics in free-ranging Alouatta spp. are well-documented, little is known about YFV infection in other Neotropical non-human primates (NHPs), particularly in captive settings. Here, we report eight NHP fatalities associated with YFV occurring in early 2025, in the Colombian department of Putumayo, a known endemic area.

Cases description

Between February and May 2025, eight fatal YFV cases were confirmed via RT-PCR in four NHP genera-Cebus albifrons, Ateles fusciceps (IUCN-endangered), Lagothrix lagotricha (vulnerable), and Aotus spp.-housed at wildlife centers or found nearby. Clinical signs included jaundice, lethargy, dyspnea, and mucosal
