 AB    OBJECTIVE: To describe the AIDS epidemic in Portugal and the major
       trends and features, in terms of the most relevant epidemiological and
       demographic data. METHODS: Review of notifications from all reported
       cases fulfilling the European AIDS surveillance case definition, send to
       the National Committee on AIDS for a 10 year period (1983-1993).
       RESULTS: By 31st December 1993, 1641 cases of AIDS had been reported in
       Portugal. The distribution according to the type of virus showed 1470
       (90.9%) cases infected by HIV1 and 146 (9.0%) infected by HIV2. Eighteen
       cases reported coinfection with both viruses, and 7 were undetermined at
       the time of notification. The transmission categories show homosexual
       and bisexual males representing 605 (38.5%) of reported cases,
       heterosexual transmission 455 (28.9%), and IVDU 364 (23.1%) cases; race
       (caucasians 79.6%, black 7.5%), residence in pattern II countries
       (20.3%) and partner's origin were analyzed. CONCLUSIONS: The patterns of
       spread of HIV1 and HIV2 and the resulting AIDS epidemic have shown
       consistency from 1983 to 1993, with the country reporting the highest
       number of AIDS cases due to HIV2 in Europe. Trends in transmission
       categories, type of human immunodeficiency virus, the sex ratio and
       other demographic features have been similar throughout the first ten
       years of the epidemic but a reversal of the proportions of these
       features is occurring, with a epidemiological pattern still different
       from other european countries.
