Public health authorities in Bolivia and Brazil continue to report cases of Oropouche fever.
In Bolivia, Irupana, Cajuata and Chulumani municipalities in La Paz have reported 74 confirmed and suspected cases. Beni region has reported 53 cases.
In Brazil, there have been 9 cases in Valença and Laje, Bahia State.
Oropouche fever is caused by Oropouche virus (OROV) which is transmitted by midges and mosquitoes. Large outbreaks of oropouche fever can occur.
Symptoms typically start 4–8 days after being bitten, and can include fever, chills, headache, muscle and joint pain, dizziness, stomach pain, vomiting, rash, or sensitivity to light.
Most people recover after a week without long-term effects. Severe illness is very rare, but can result in meningitis.
Treatment is supportive. There is no vaccine for Oropouche fever.
All travellers to endemic regions are potentially at risk of Oropouche fever and should be aware of this infection.
Travellers developing a fever and/or flu-like symptoms either during or on return home from travel to outbreak areas are advised to seek medical attention as soon as possible.
