Sickle cell anaemia is an inherited genetic disease that affects the hemoglobin chains of red blood cell hemoglobin, carrying oxygen less well through the body. It is a rare disease, however, it is the most widespread genetic disease in the world and especially widespread in sub-Saharan Africa. It causes anemia, painful seizures that affect several organs, it is also called sickle cell anemia, this disease results in a deformation of red blood cells in the form of sickle or a crescent moon, which prevents normal circulation in the blood vessels. This will cause blood flow to be blocked. It is a disease that is geographically concentrated in certain areas such as Africa, India, Brazil, the Mediterranean Basin, but it is currently found everywhere because of mass migration and has been considered since 2008 by United Nations as a public health priority. Sickle cell disease affects black people and accounts for 50% of deaths in childhood.
