[Editorial] Sickle cell disease: a neglected health priority

September is National Sickle Cell Awareness Month in the USA, designated by Congress to help focus attention on the need for research and treatment of sickle cell disease. The Sickle Cell Disease Association of America (SCDAA)'s theme for this year is “Sickle Cell Matters 2025” and calls for Americans to donate blood, raise awareness, and dispel myths surrounding the disease. Sickle cell disease affects over 100 000 individuals in the USA, and there are about 7·7 million people living with the disease worldwide, with prevalence growing globally.
