Bolivia's Chikungunya Outbreak Accelerates in 2025

Like many countries in South America, the Plurinational State of Bolivia has been confronted with a multi-year outbreak of Chikungunya.

To alert international travelers visiting Bolivia, the U.S. Centers for Disease Control and Prevention (CDC) issued a Level 2 Travel Health Advisory on June 26, 2025, stating that this year's Chikungunya outbreak is centered in Bolivia's Santa Cruz department.

According to recent data, Bolivia welcomed around 984,000 international tourists in 2024.

Data released at the end of June 2025 indicates Bolivia has reported 3,863 Chikungunya cases this year and 505 cases in 2024.

So far in 2025, about 38 people have returned to the U.S. infected with the Chikungunya virus.

The CDC advises that if you are pregnant, you should reconsider travel to the affected areas, especially if you are nearing the time of delivery. Mothers infected around the time of delivery can pass the virus to their baby before or during delivery.

Newborns infected in this way or by a mosquito bite are at risk for severe illness, including poor long-term outcomes.

Furthermore, vaccination is recommended for most travelers who are visiting an area with a Chikungunya outbreak.

As of June 30, 2025, Chikungunya vaccines are approved for use by the CDC and are commercially available at travel clinics and pharmacies in the United States.
