There is a risk of Oropouche fever in Peru, with the risk of infection highest January-March. Health authorities reported 94 Oropouche fever cases in six departments (Madre de Dios, Cusco, San Martin, Cajamarca, Loreto, and Ayacucho) between 2016, and 2022, and two cases in 2023.

More severe cases may result in meningitis.
