title: A new method for evaluating the hepatitis risk of the multiply-implicated donor.
abstract: The usual method of estimating probability of infectivity for donors implicated in more than one case of post-transfusion hepatitis fails to take adequate account of the donor's past history and underestimates the risk of infectivity. A corrected method of calculation is presented and shown to give substantially different results.
