Mortality is high, especially in the early childhood years. Since the introduction of widespread penicillin prophylaxis and pneumococcal vaccination, a marked reduction has been observed in childhood deaths. The leading cause of death is acute chest syndrome. Children have a higher incidence of acute chest syndrome but a lower mortality rate than adults; the overall death rate from acute chest syndrome is 1.8% and 4 times higher in adults than in children. Causes of death are pulmonary embolism and infection.
