TTIs are caused by different viral, bacteria and parasitic agents. Of these agents HBV, HCV, HIV, T.Pallidum and malaria are of great clinical significance. Pakistan is facing the problem of having high prevalence of TTIs. Here blood and its components transfusion caused known cases of HIV, HBV, HCV, T. Pallidum and Malarial Parasites infections.
