Abstract Oropouche fever is caused by the Oropouche virus (OROV; Bunyaviridae , Orthobunyavirus), one of the most frequent arboviruses that infect humans in the Brazilian Amazon . This year, an OROV outbreak was identified in Brazil , and its vertical transmission was reported, which was associated with fetal death and microcephaly. We describe the clinical manifestations identified in three cases of congenital OROV infection with confirmed serology (OROV-IgM) in the mother-newborn binomial . One of the newborns died , and post-mortem molecular analysis using real-time RT-qPCR identified the OROV genome in several tissues . All three newborns were born in the Amazon region in Brazil , and the mothers reported fever, rash, headache, myalgia, and/or retro-orbital pain during pregnancy . The newborns presented with severe microcephaly secondary to brain damage and arthrogryposis , suggestive of an embryo/fetal disruptive process at birth . Brain and spinal images identified overlapping su...

We conducted a systematic review examining 30 reported cases of avian influenza in pregnant women . We found high mortality rates for mothers (90.0%, 27/30) and their babies (86.7%, 26/30) when women were infected with avian influenza virus during pregnancy. Despite being a high-risk population and having worse health outcomes across multiple pandemics , pregnant women are often excluded from vaccine trials . However, as the risk for a new pandemic increases and human vaccines against avian influenza are developed, early inclusion of pregnant women in clinical trials can inform the risk-benefit analysis for both the mother and their newborn infant. Early inclusion of pregnan...
