Estimated Current Risk Of Transfusion-Transmitted Infection From A Unit Of Screened Blood (1997)

HEPATITIS
(Schreiber et al.)		 B: 1 in 63,000 *range: 1 in 31,000-147,000
C: 1 in 103,000 *range: 1 in 26,000-288,000
AIDS/HIV** Lackritz et al. 1 in 700,000 *range: 562,000-825,000
Schreiber et al. 1 in 676,000 *range: 277,000-3,800,000
HTLV-I/II*** Schreiber et al. 1 in 641,000 *range: 256,000-2,000,000

* - 95% confidence interval

** - Projected to account for reduced risk expected after introduction of HIV antigen screening (March, 1996)

*** - Human T-lymphotropic viruses, types I and II (NOT HIV)
