Voluntary outreach counselling and testing for HIV and STI among men who have sex with men in Antwerp.
BACKGROUND
High risk settings for transmission of HIV and sexually transmitted infections (STI) offer an opportunity for screening of difficult to reach risk groups.


METHODS
Free, anonymous counselling and testing for HIV, syphilis, Chlamydia and hepatitis B/C were offered to visitors in two selected gay venues in Antwerp, by a multidisciplinary team. Participants completed an anonymous questionnaire. The STI-test results were communicated by cell phone using standardised text messages.


RESULTS
In total, 137 MSM were tested. Facilitators of risky sexual behaviour (alcohol and drug use) were reported by 34 and 21%, respectively. Four men (3%) were newly diagnosed with HIV; 25 men (18%) had an active, transmittable STI. Infected MSM were significantly less often registered with a fixed general practitioner (GP).


CONCLUSIONS
Outreach testing in gay venues is a suitable method to detect MSM at risk for HIV/STI. Although the outreach approach is very labour intensive, it shows a high yield of new STI-diagnoses that are not detected in the regular health system.
