Seroprevalence and trends of transfusion transmitted infections at Harar blood bank in Harari regional state, Eastern Ethiopia: eight years retrospective study.

The magnitude of transfusion transmitted infections was lower than the previous studies conducted in Ethiopia. However, the decline in trends of transfusion transmitted infections has not been significant for some pathogens. Therefore, strict adherence with the criteria of preliminary blood donor selection should be implemented to reduce the amount of blood being withdrawn from transfusion after collection and screening.
