Oropouche fever outbreak in Brazil: an emerging concern in Latin America

The current outbreak of Oropouche virus (OROV) infection in the Amazonas and Acre states of Brazil presents considerable public health concerns, including the risk to travellers visiting these regions. Given the endemic nature of OROV infection in these areas, the US Centers for Disease Control and Prevention has recently elevated Brazil to a level 1 Travel Health Alert. Oropouche fever, resulting from OROV infection, is an emerging zoonotic disease transmitted primarily via the bites of infected Culicoides paraensis, commonly known as biting midges, and sometimes via mosquitoes.
