Previous evidence has suggested that Northern Ireland is a low seropre
valence area for HIV infection. The Unlinked Anonymous HIV Prevalence
Monitoring Programme initiated in England; and Wales in 1990 was exten
ded to Northern Ireland in 1992. Patients attending the Genitourinary
Medicine Clinic at the Royal Victoria Hospital have, with informed con
sent, been tested anonymously for HIV infection since that time. The r
esults of the survey between 1992 and 1995 have shown an overall serop
revalence rate of 3.01% for homosexual/bisexual men, 0.08% for heteros
exual men, and 0.05% for heterosexual women. These results confirm the
previous impression of low HIV seroprevalence in Northern Ireland and
the survey provides an excellent longitudinal study by which changes
may be monitored.
