Molecular Epidemiology of Oropouche Virus, Ceará State, Brazil, 2024

Emerging Infectious Diseases
During May–December 2024, we detected Oropouche virus (OROV) in 13.9% (263/1,890) of febrile patients in Ceará state, Brazil. Genomic sequencing revealed those cases were caused by a novel OROV reassortant previously identified in the Amazon region. Our
