Hi Vijeta,

to the site.
Thal. Major is
not caused by ANYTHING. Patients are BORN with it. So, there is no chance that you can GET this condition. It is not a contagious disease. It is a genetically inherited condition caused by inheriting affected genes from the parents.
If you are sure that his father is Thal.
Major and has been on blood transfusions since childhood then your finance has to be Thal.
Minor.
I would strongly recommend you to get yourself tested for Thal. trait. You
must be normal i.e no Thal Trait/carrier for further considering him for your partner.
I wish you all the luck and I hope that you are normal so that you don't have any risk of having a Thal. Major child with your partner being Thal. Minor
Take care, Peace!
