- We all learned in medical school that hemoglobinopathies are prevalent, at least in part, because carriers benefit from protection against malaria it is well established that both sickle cell trait and α+-thalassemia alter red cell physiology to put the parasite at a disadvantage sickle cell trait may attenuate malarial infection by reducing.
