Oropouche Outbreaks Continue in April 2025

Last summer, the Pan American Health Organization issued several epidemiological alerts about Oropouche cases, including deaths, in the Americas. Unfortunately, these outbreaks continue today.

To notify international travelers, the U.S. Centers for Disease Control and Prevention (CDC) recently updated its Travel Health Advisory for Oropouche fever outbreaks in several countries across the Region of the Americas.

A Level 1, Practice Usual Precautions advisory was reissued on April 9, 2025, for Barbados, Bolivia, Brazil, Colombia, Cuba, Ecuador, Guyana, Panama, Peru, and Venezuela.

Previously, a Level 2 advisory was issued for Oropouche in some regions of Brazil and Panama (Darién Province).

The CDC says Oropouche is a disease caused by the Oropouche virus and is spread primarily through the bites of infected biting midges and infected mosquitoes.

The CDC is working with other international partners to learn more about the potential risks of Oropouche during pregnancy. Additionally, healthcare providers should inform pregnant women considering travel to areas with reported Oropouche virus transmission of the possible risks to the fetus.

Furthermore, a recent publication described a patient with Oropouche who had the virus and viral RNA detected in bodily fluids, including semen. 

As of April 12, 2025, no Oropouche vaccine is available.
