Applicability of available methods for incidence estimation among blood donors

Abstract Incidence rates of major transfusion transmissible viral infections have been estimated threugh widely used sereconversion approaches and recently developed methods.A quality database for blood donors and donations with the capacity to track donation history of each donor is the basis for incidence estimation and many other epidemiological studies.Depending on available data,difierent ways have been used to determine incidence rates based on conversion from uninfected to infected status among repeat donors.
