Oropouche fever is endemic to the Amazon Basin. The risk of Oropouche fever infection is highest during Brazil’s rainy season, especially in rural areas. Oropouche fever is a disease caused by Oropouche virus (OROV) and is primarily transmitted to humans through the bite of midges (small flies) or mosquitoes. Symptoms typically appear 4 to 8 days after being bitten but can develop up to 12 days after. Symptoms include headache, fever, muscle aches, stiff joints, chills, nausea, and vomiting. More severe cases may result in meningitis.
