All blood donations in the United States are screened for human
immunodeficiency virus (HIV), the virus that causes AIDS; in spite of
this, potentially infectious donations are still made by donors who are
infectious but have not yet developed detectable HIV antibodies. A
steady-state model for blood donations is used to calculate the expected
number of potentially infectious blood donations made by repeat blood
donors in a specified time interval. The expected number of potentially
infectious donations made by each infectious blood donor who
subsequently becomes HIV positive is calculated, and estimators of this
quantity are presented. The relative risks due to donations from repeat
and first-time donors is discussed. Estimates of the proportion of all
blood donations made at 19 American Red Cross regional blood centers
that are potentially infectious are presented.
