Answer

The human immunodeficiency virus (HIV), a member of the Lentivirus family of retroviruses, is the causative agent of acquired immunodeficiency syndrome (AIDS). In the United States, more than 1.2 million people are living with HIV, and 1 in 8 of them don't know it. Individuals who engage in male-male sexual behavior accounted for 82% (26,375) of HIV diagnoses in men and 67% of all diagnoses in 2015. [17] Less than 1% of HIV cases are attributed to blood or blood product transfusions. Note:  The risk of transmission of HIV through blood products is as follows [18, 19, 20]

  • United States - 1 in 2 million units (2,135,000)

  • Canada - 1 in 7.8-10 million units in Canada

  • Parts of Europe - 1 in 1 million to 1 in 5 million units
