Sickle Cell Anemia Sickle cell anemia is an inherited blood disease. The word anemia is defined as meaning that the blood does not have the required number of red blood cells. These cells take on a crescent shape‚ which is where the disease takes its name from the abnormal sickle shapes of the cells. It is commonly found in people from Africa‚ the Mediterranean region‚ southern India and the Middle East. “This disease of the blood was first discovered in 1910 in a black college student from the
