Abstract

Oropouche virus (OROV) is an emerging arbovirus that has shown rapid geographic expansion across the Americas. In Cuba, the first cases were confirmed in 2024. This study describes OROV positivity in municipalities of Camagüey Province between June and October 2025 and characterizes its distribution by sex and geographic area. An observational, descriptive, cross-sectional study was conducted. A total of 103 suspected cases reported in thirteen municipalities were included. Confirmation was performed by real-time RT-PCR at the reference laboratory of the "Pedro Kourí" Institute of Tropical Medicine (IPK) in Havana. Twenty-seven cases were confirmed (26.2 % positivity): thirteen women (48.1 %) and fourteen men (51.9 %). Viral circulation was detected in five municipalities (38.5 %): Camagüey, Florida, Minas, Céspedes, and Vertientes. Positivity reached 100 % in some subgroups (Florida, men, June; Céspedes, both sexes, July). Circulation of OROV was corroborated in Camagüey Province, with a balanced distribution by sex. Strengthening entomological and clinical surveillance is recommended, especially during periods of high arbovirus transmission.
