The cohort study records the number of the included patients, the number of patients on ART (approximately
85% of all patients on ART in Austria are included in the cohort), the number of “late“ presenters and finally
the number of the patients who died with or without AIDS. We estimate that there are currently about 7500 -
8500 HIV infected persons living in Austria.
The median age at the diagnosis lies between 30 and 40 years since 1990. 27.8% of the patents with a
follow-up in the last 12 months are female. The rate is highest in Upper Austria (35.5%) and Vorarlberg
(33.3%). In the subgroup of the heterosexually infected, the rate of the women is 51.5%. It is highest in
Upper Austria (56.6%), Vienna (52.4%) and Vorarlberg (52.2%). Among patients newly diagnosed in 2012,
34.6% have been infected through heterosexual contacts. Since 2000, 41.4% of newly diagnosed HIV infections
were transmitted through heterosexual contacts.
