Abstract

We report seven patients with detected o'nyong'nong virus infection, presenting with acute febrile illness at two tertiary hospitals in Nigeria. The clinical presentation mimicked malaria and Lassa fever, highlighting the need for expanded arboviral surveillance and diagnostics to distinguish emerging viral infections in endemic settings.
