From a story on a “floating hospital” set up off the coast of Haiti, with Haitian-Creole interpreters onboard:

“Doctors said the translators play a critical role, putting the patients at ease and providing the doctors with medical history.”

‘This is a foreign land, they don’t know anybody, it’s all strange to them,’ translator Geordany Avescat, 42, said of the patients who are airlifted via helicopter to the giant ship in the Port-au-Prince harbor. Avescat, who has a brother in Port-au-Prince, also put his name in to serve on the Comfort and said the translators also serve as advocates for the patients.”
