[|AI|]  Hi, Thank you for posting your query. Unfortunately your query does not give out most of the details, which could enable us to give you a good answer. What do you mean by EBS? Generally, after bone marrow transplant, patients are more prone to develop infections, as their immunity is lowered due to use of immunosuppressant Chat Doctor. If you can upload some more details, it would be helpful. I hope it helps. Please get back if you require any additional information. Wishing you good health,
