A2 - Novelli, Enrico M. PY - 2021 T2 - Sickle Cell Disease AB - Jamaica is an island in the Caribbean approximately 140 km south of Cuba. Maximum dimensions are 235 km long and 84 km wide, with a land mass of 10,911 km2 and an estimated population of 2.9 million in 2018. The people are predominantly of West African origin, with smaller groups from India, China, the Mediterranean, and northern Europe, especially the United Kingdom. This diversity results in a population where 10% have the sickle cell trait, 3.5% have the HbC trait, and 0.9% have the β thalassemia trait. Although Jamaica is in many ways a developing society, it has excellent public health and medical facilities and is malaria free. Furthermore, some sophistication results from its closeness geographically to the United States and culturally to the United Kingdom, which also means that these countries are home to a large Jamaican diaspora. Within Jamaica, despite a shift of the population toward urban centers, nearly half the people reside in rural areas where they maintain stable households. This population structure is invaluable for long-term follow-up of patients and, hence, ideal for studies of the natural history of disease generally and has provided a unique “island laboratory” for studies of sickle cell disease.
