If you are traveling from outside Costa Rica, please consider that you may require vaccination against some diseases found in other parts of the world. There is currently no risk of yellow fever in Costa Rica, although Costa Rican government requires proof of yellow fever vaccination only if you are arriving from a country with risk of yellow fever. We recommend to ask your doctor what vaccines and medicines you need based on where you are going, how long you are staying, what you will be doing, and if you are traveling from a country other than the US.
