Oropouche Fever Outbreaks Continue in the Americas

The U.S. Centers for Disease Control and Prevention (CDC) reported today that Oropouche fever outbreaks occur in 21 countries, including parts of Brazil, Bolivia, Colombia, Peru, Cuba, Ecuador, Panama, and Peru.

As of June 5, 2024, the CDC's Travel Health Advirosy says travelers should seek medical care if they develop high fever, headache, muscle aches, stiff joints, nausea, vomiting, chills, or sensitivity to light during or after travel.

Since it was first isolated in Trinidad and Tobago in 1955, more than half a million Oropouche cases and at least 30 major outbreaks have been reported. However, these data are difficult to quantify due to the lack of diagnosis.

In 2024, the Pan American Health Organization reported over 5,000 confirmed cases of Oropouche in four countries in the Region of the Americas.

This illness can occur in people of any age and is often mistaken for dengue, which is also impacting these populations.

The CDC says Oropouche fever is spread by the bite of infected midges (small flies) and mosquitoes.

Unfortunately, Oropouche infection treatment is supportive, as no specific medications or vaccines are available.
