[Absence of delta agent infection in high risk male subjects infected with B virus and human immunodeficiency virus].

Positive contacts to DV were investigated among 50 males, 48 homosexuals and 2 heterosexuals intravenously drug-addicts. None shown presence of anti-VD antibodies, while 98% and 50% from the total group demonstrated confirmed reactivity to HIV and HBV respectively. Further, 19 subjects who notified 5 or more sexual partners per year, shown one or more positive HBV markers, finding only observed in 6 subjects from 31 who notified less than 5 partners per year (p less than 0.001). The absence of DV positive contacts suggest that epidemiologically the DV seems to be loss of non-influenced by the sexual condition of the exposed population.
