In February 2026, the U.S. Centers for Disease Control and Prevention (CDC) issued an urgent travel alert for Bolivia due to an outbreak of the chikungunya virus. The affected regions, primarily Santa Cruz and Cochabamba Departments, prompted the CDC to classify the alert as Level 2. This designation indicates that travelers should take enhanced precautions to safeguard their health while visiting these areas plagued by the virus. The chikungunya virus, transmitted by infected mosquitoes, can cause a range of symptoms including fever and severe joint pain that typically manifest three to seven days post-infection. While most individuals recover from the virus within a week, some may experience prolonged joint pain lasting for months or even years. The CDC has stressed that fatalities from chikungunya are rare, which can provide some reassurance for travelers. Nonetheless, the agency is recommending that all travelers to the affected regions receive the chikungunya vaccine and follow preventative measures against mosquito bites. This includes using insect repellent, wearing long-sleeved clothing, and opting for accommodations equipped with air conditioning or screened windows and doors. As the chikungunya outbreak unfolds, it is essential for travelers to remain vigilant and aware of the health risks associated with visiting Bolivia. The CDC's recent advisories highlight a growing concern over viral outbreaks in various international destinations, such as recent alerts for other regions like the Seychelles, Cuba, Bangladesh, and Sri Lanka. This escalating trend of diseases impacting popular tourist locales has necessitated increased public health efforts to communicate risks effectively to potential travelers. In addition to the chikungunya outbreak, Bolivia is also under a Level 1 alert for measles, which has been on the rise globally. The CDC recommends visitors ensure they are fully vaccinated with the measles-mumps-rubella (MMR) vaccine before undertaking international travel. The implications of these health concerns, combined with the recent decrease in international tourist arrivals due to the pandemic, call for a careful evaluation of travel plans to Bolivia. Travelers should stay informed about both chikungunya and measles outbreaks in order to protect their health and the health of others while traveling abroad.
