Kevin will turn 12 in July, but he seems older when he speaks clearly about the illness he has been suffering from for a few months. Last February, he was diagnosed with aplastic anemia, a rare condition in which red bone marrow disappears and red blood cells, white blood cells, and platelets are no longer produced. He needs a bone marrow transplant. So far, they haven't found a donor, and the child has started treatment at Vall d'Hebron Hospital, although they will still have to wait a few weeks to see how he responds.
