This is very sad indeed.  It is so awful that the blood is not safe for some thalassemia patients.  I don't know if all blood banks throughout the world are equipped to deal with blood bourne illness in the blood.  My heart goes out to the children and their parents.  
However, I am appalled that they are referring to the existence of thalassemia patients as 'a joke'.  Needing blood for survival is no different than anyone else with a chronic illness requiring either medicine or other products for survival.  Whether it be asthma, diabetes, immune deficiencies, hypothyroid, lupus, organ failure requiring transplant etc etc.  People with thalassemia borrow blood - hopefully the blood is safe - and they are capable of living very productive lives.  The existence of anyone here is NOT a joke!!  I am sorry that the newspaper refers to it that way.
