Background: Second generation surveillance is a central feature of HIV/AIDS policy in Switzerland. Behavioural surveys in the general population, men having sex with men (MSM) and injecting drug users (IDU) have been regularly conducted since the early nineties. After peaking at 2144 cases in 1991, the number of new HIV cases notified to the Ministry of Health decreased in each subpopulation until 2000 (n=578) and then rose again to 735 in 2006. The recent increase is mainly due to MSM.
Methods: In the general population, representative cross-sectional telephone surveys have been conducted 11 times since 1987. Surveys in convenience samples of MSM, recruited through gay newspapers and gay organisations, have been conducted 5 times since 1992. Surveys among IDU's attending needle exchange programmes have been conducted 5 times since 1993. Condom statistics, available since 1986, are included in the behavioural surveillance system.
Results: In the general population aged 17-30, systematic condom use with casual partners in the last six months increased from 8.0% in 1987 to 75.8% in 2007. The proportion of MSM reporting anal intercourse with casual partners in the last 12 months increased from 61% in 1992 to 79% in 2007 (lowest value 56% in 1994) and unprotected anal intercourse with these partners increased from 14 % in 1992 to 24% in 2007 (lowest value 9% in 1994). The proportion of IDUs reporting borrowing used injection equipment decreased from 16.5% in 1993 to 8.9% in 2006. The ratio condoms released to retail/population aged 15-65 increased from 1.68 in 1986 to 3.8 in 2006.
Conclusions: It has been possible to maintain a coherent behavioural surveillance system on a long-term basis, allowing for the monitoring of HIV prevention policy outcome and forseeing the development and distribution of new HIV cases in the population.
