Yes Did you are correct. From your reference: Those who have minor degrees of thalassemia, similar to those with sickle-cell trait , have some protection against malaria , explaining why they are more common in regions of the world where malaria exists.
Both diseases have a deformity of the red blood cell. The cause seems different. Confusing to me.

Thank you all for your responses. It is great to know that there is hope for this person.
