WebAs the sickle cells clog the blood vessel, they can block blood flow to various parts of the body, causing painful episodes (known as sickle cell crises) and raise the risk of infection. In addition, sickle cells die earlier than healthy cells, causing a contant shortage of red blood cells, also known as anemia. SCD is diagnosed by a blood test. WebThis reduces the elasticity of red blood cells, causing extreme pain, extensive tissue destruction and anemia. The allele is maintained at a high level in large swaths of African populations because, in the heterozygous state, it affords some protection against the malaria parasite, which replicates in red blood cells (Aidoo et al., 2002).
