In the department of Tolima, 28 cases were identified among travelers during 2025–2026, including 14 deaths, highlighting the role of travel-related transmission in the ongoing outbreak.
Between 2024 and 17 May 2026, Colombia reported 192 confirmed yellow fever cases and 85 deaths across ten departments.
Vaccine hesitancy remains a challenge, with local health officials noting similarities to resistance seen during the COVID-19 pandemic.
Yellow fever is endemic in most parts of Colombia with increasing numbers of cases in previously not affected regions. Vaccination against yellow fever is highly recommended for all travellers. In addition, it is mandatory for the following conditions:
- Anyone traveling by land or water within Colombian territory must carry a yellow fever vaccination card or certificate. This measure applies to everyone and covers all types of transport, including cars, buses, and boats.
- Visitors to enter any Natural National Parks in Colombia (enforced at entry gates).
