Abstract:
The aim of our study was to determine human immunodeficiency virus 1 subtypes in Scottish blood donors. We were able to document virus subtypes present in this population over a period of 19 years and examine associated risk factors where available. Subtype B was found to be the predominant cause of human immunodeficiency virus 1 infection in Scottish blood donors with subtype C increasing in this population after 2002. Non-B subtypes were found mainly in heterosexuals but also in all other risk categories with the exception of men having sex with men (MSM). Within Scotland there is an increase in transmission via heterosexual contact and the consequential introduction of non-B subtypes.
