Denis transfused the blood from a sheep to a 15-year old boy and later to a labourer, both of whom survived the transfusions. In 1818, British obstetrician James Blundell successfully transfused human blood to a patient who had hemorrhaged during childbirth. In 1901, Karl Landsteiner, an Austrian physician discovered the first human blood groups, which helped transfusion to become a safer practice.
The modeled risk for HIV infection from transfusion of blood products in the United States declined from one in 450,000--600,000 donations in 1995 to one in 2,135,000 donations from 1995 to 2001 after the introduction of NAT in 1999 (8) and was recently updated to one in 1,467,000 based on data from 2007--2008, which incorporates the increased incidence of HIV among blood donors (2).
