Blood transfusion and AIDS in the USA

We have examined data for 3518 cases of transfusion-acquired AIDS (TA-AIDS) onsets as reported to the USA Centers for Disease Control (CDC) through 30 June 1990. We discarded 1077 of these records because of missing or uncertain date of infection. We present here infection and onset data on the remaining 2441 cases in a Rees Plot of year of onset vs. year of infection. This is probably the only class of AIDS patients for whom the date of infection is reasonably ascertainable. Also the large number of cases which we present, by cohorts of year of infection, should be useful for epidemiology and for public health planning purposes.
