The child was brought to a health provider with swollen hands and feet, labored breathing, and red urine. Tests found low blood oxygen and red blood cell count. Additional testing confirmed sickle cell anemia through detection of hemoglobin S, SS, SB, or SC. Sickle cell anemia is caused by a genetic mutation that substitutes valine for glutamic acid in the hemoglobin protein, weakening red blood cells and reducing their lifespan to around 20 days. Treatments aim to supplement proteins, vitamins, antibiotics to prevent infection, and blood transfusions, but there is currently no cure.
