The Oropouche virus outbreak in 2023 drew attention in Brazil and other Latin American countries not only because of its scale—with more than 30,000 cases recorded nationwide—but also because of the first confirmed death in the country caused by the disease and its rapid spread to all states, extending beyond the Amazon region. In light of this situation, the World Health Organization (WHO) expressed concern earlier this year and called for the accelerated development of prevention and control tools against this pathogen, which was virtually unknown until then.
