Following the significant increase in yellow fever cases in 2025 (see EpiNews 13 June 2025), the Swiss Expert Committee for Travel Medicine has adapted the risk areas where yellow fever vaccination is recommended. Notably, in addition to previously identified areas, the revised recommendations now include the following newly designated risk areas:
All countries:
- expansion of risk for stays up to 2’500m elevation in all countries
- vaccination may be considered for regions marked in green on the CDC map
Peru: Machu Picchu and all Inca trails
Colombia: islands of San Andrés and Providencia, stays in all national parcs (new entry requirement!)
For details, see yellow fever recommendations and countries’ entry requirements at the respective country page on www.healthytravel.ch and CDC map.
