Sickle Cell Disease Statistics

Sickle cell disease turns into a race against time and access, with fewer than 50% of children surviving to age 5 in low and middle income settings, and a median US age at death of 42. For people living with SCD in the US and beyond, the burden is measurable in ways that change care choices, from vaso occlusive pain and acute chest syndrome rates to stroke risk, kidney disease, and gene and cell therapy costs.

Sickle cell disease affects about 5.0 million people worldwide, yet the outcomes can diverge dramatically depending on access to care. In low and middle income settings, fewer than 50% of children with SCD survive to age 5 without adequate treatment, while in the US the median age at death is 42 years. Even in places with advanced treatment, adults can still face yearly vaso occlusive pain events and substantial hospital and healthcare costs.
