Exploring the challenge of diagnosing and tracking Oropouche virus during Brazil's largest recorded dengue epidemic in 2024.

ABSTRACT:

Background

In 2024, Brazil experienced its largest dengue virus (DENV) epidemic alongside the widest spread of Oropouche virus (OROV) to date. This scenario may have strongly impacted public health surveillance efforts, as DENV and OROV infections often lead to similar clinical signs and symptoms, making clinical differential diagnosis challenging. Herein, we investigated whether the co-circulation of DENV and OROV in Brazil in 2024 may have hampered OROV detection and tracking, potentially contributing to possible underdiagnosis.

Methods

The number of confirmed cases of dengue and Oropouche in 2024, as well as the probable states of infection, were collected on June 9, 2025, from the Brazilian Ministry of Health database. For dengue, cases were analyzed according to the dia
