For the first time, the Oropouche virus has been reported in Europe, affecting travelers returning from the Americas. Detected in Spain, Italy, and Germany, this virus is carried by midges, a type of biting fly, and mosquitoes. It causes symptoms similar to Zika virus, such as fever, muscle aches, and rash. In about 4% of cases, it can lead to nervous system inflammation. Despite recent reports linking the virus to poor pregnancy outcomes in Brazil, including pregnancy loss and microcephaly, there is currently no confirmed connection.The Oropouche virus was first identified in Trinidad and Tobago in 1955 and has since caused outbreaks in South America, Central America, and the Caribbean. Recent outbreaks have been reported in Brazil, Bolivia, Colombia, Peru, and Cuba. The virus spreads primarily through midges of the species Culicoides paraensis and some mosquitoes. European midges and mosquitoes are not known to carry the virus, making local transmission in Europe unlikely.Travelers to areas where the virus is prevalent should use insect repellent, wear long-sleeved clothing, and use insecticide-treated bed nets. There is no vaccine for Oropouche virus, so preventative measures are essential. Although the link between Oropouche virus and poor pregnancy outcomes is still under review, similar precautionary measures for Zika virus should be followed in affected regions.
