[HIV seropositivity in promiscuous heterosexual, homosexual and bisexual men and patients voluntarily reporting for screening in Hungary between 1 January 1986 and 31 December 1989].

The cumulative seroprevalence was 5.21% among the homo/bisexual men in the four years. As well as in Budapest, we experienced the increase of seroprevalence in the country, too, after a decrease in 1988. The cumulative seroprevalence was 0.44% with men and 0.04% with women in the group of the voluntary reporters in the mentioned period. The same indexes were 0.07% for men and 0.019% for women in the group of the STD patients. Seroprevalence with men increased significantly in the last year. Hungary belongs to the low-incidence area among the European countries, even though the group of homosexuals can be considered moderately infected, seroprevalence is increasing in Budapest as well as in the country and heterosexuals are also affected.
