title: Different distribution of HIV type 1 genetic variants in European patients with distinct risk practices.
abstract: The use of two genetic markers has permitted the analysis of the distribution of two different human immunodeficiency virus type 1 (HIV-1) variants in patients of the homosexual (HO) and intravenous drug user (IDU) groups in distinct European countries. In Germany, Holland, and Italy the variants circulating in each risk group of HO and IDU patients were genetically distinguishable according to the genetic markers used. In contrast, in France and Spain, the same variant has been recovered from patients with different risk practices. These data highlight the diversity of the HIV-1 epidemic in Europe and the different patterns of HIV-1 variant distribution in European countries.
