                           What is thalassemia?
                           •	     It is a hereditary blood cell disorder.
                           •	     It may impair the body’s ability to carry oxygen in the blood.
                           •	     It is characterized by a low hemoglobin level and a lower number of red blood cells than

                           What causes thalassemia?
                           It is an inherited blood disease passed by genes from parents to their children.
                           Thalassemia is not contagious. If only one of your parents is a carrier of thalassemia, you 
                           probably won’t have symptoms, but you’ll be a carrier of the disease. If both of your parents 
                           are carriers of thalassemia, you have a greater chance of inheriting a more serious form of the 
                           disease.
