In the southern part of the Philippines, specifically in the Sulu Sea, lies the island of Culion. This small island, which is part of the Calamian Islands in the province of Palawan, has a significant place in the country's history, particularly in the history of public health. Culion is famously known as the site of a former leper colony, and the term "Culioneros" translates to "those from Culion."
