When hotness of body is accompanied by jaundice anorexia and anaemia recurring a week after blood transfusion what might be the diagnosis?

The symptoms of hotness of the body, jaundice, anorexia, and anemia occurring a week after a blood transfusion suggest the possibility of a delayed hemolytic reaction, particularly due to an immune response against donor red blood cells. This condition can occur if the recipient has antibodies that were not detected before the transfusion. The recurring anemia and jaundice indicate hemolysis, where the body is breaking down the transfused red blood cells. It is essential to perform further testing, including blood typing and cross-matching, to confirm the diagnosis and manage the condition appropriately.
