No Specific Treatment or Vaccine Approved for Oropouche

During the summer and fall of 2024, the Pan American Health Organization (PAHO) issued several epidemiological alerts about Oropouche cases, including deaths, in the Region of the Americas.

Significant outbreaks have been reported in Brazil and Cuba.

On October 25, 2024, the U.S. CDC reaffirmed it is working with PAHO and other international partners to learn more about the potential risks of Oropouche.

The CDC's Level 1 - Practice Usual Precautions, Travel Health Advisory, says Oropouche is spread primarily by the bite of infected midges and mosquitoes.

Oropouche symptoms include headache, fever, muscle aches, stiff joints, nausea, vomiting, chills, and sensitivity to light. They typically start 3–10 days after being bitten and last 3–6 days, and most people recover without long-term effects.

The CDC says there is no specific treatment or vaccine for Oropouche.
