Oropouche virus (OROV), a member of the Peribunyaviridae family, has emerged as a significant arboviral threat, particularly in South and Central America. Traditionally causing mild febrile illness, recent outbreaks have revealed severe clinical outcomes, including aseptic meningitis, encephalitis, and, more recently, vertical transmission leading to congenital anomalies and fatalities. Environmental changes, including deforestation and climate shifts, have expanded the virus's geographic range, as seen in Brazil, where over 8000 cases were reported by August 2024, compared to fewer than 831 in 2023. For the first time, vertical transmission has been confirmed, with cases of fetal deaths and congenital anomalies such as microcephaly and agenesis of the corpus callosum, drawing parallels to the Zika virus outbreak in 2015-2016. Despite these alarming trends, key mechanisms of placental transmission, maternal immunity, and fetal susceptibility remain poorly understood. This perspective highlights the urgent need for a coordinated global response, focusing on enhanced surveillance in newly affected regions, vector control strategies, and research into the factors driving severe clinical outcomes. Strengthening global efforts will be crucial in mitigating the public health threat posed by OROV, particularly in light of its potential for further geographic expansion and severe clinical manifestations.
