Data from 23 European countries show that the annual number of HIV diagnoses in men who have sex with men (MSM) increased by 86% between 2000 and 2006. This paper reports the main preliminary results of a bio-behavioural survey in MSM with a specific focus on HIV prevalence and use of United Nations General Assembly Special Session (UNGASS) indicators in six cities in Southern and Eastern Europe. Time-location sampling (TLS) was used. A total number of 2,356 questionnaires and 2,241 oral fluid samples were collected (invalid samples 4.1%). The data show different socio-demographic patterns across countries regarding age, level of education, living conditions, living area and self-identity. Southern European cities had the highest percentage of people who had tested for HIV and collected the result. More than 50% of respondents in the sample from Barcelona reported having used a condom last time they had anal sex (57.2%), whilst in all other cities this proportion was below 50%. The cities with the highest HIV prevalence in MSM were Barcelona (17.0%) and Verona (11.8%) whilst lower percentages were reported in Bratislava (6.1%), Bucharest (4.6%), Ljubljana (5.1%) and Prague (2.6%). The low prevalence in Eastern European cities is encouraging. However, with the level of high-risk sexual behaviour documented and the lower frequency of HIV test seeking behaviour, there is a clear risk of an increase in HIV transmission.

Aim. Of the study is to assess HIV prevalence in the vulnerable groups namely injecting drug users (IDU), sex workers (SW), and men who have sex with men (MSM) in some of the largest Russian regiоnal capitals mostly affected by HIV infection. Materials and methods. The study involved 3744 persons from vulnerable groups enrolled by respondent-driven sampling (RDS) or time-location sampling (TLS). The study was undertaken in seven regions of the Russian Federation: Moscow, St.-Petersburg, Yekaterinburg, Krasnoyarsk, Kemerovo, Tomsk and Perm. All participants were interviewed using specially designed questionnaire and then tested for HIV. The retrospective cohort method was applied to evaluate the number of new HIV cases among respondents. Results. HIV prevalence in IDUs ranged from 48.10% [95% confidence interval (CI)=42.20.54.10%] in Krasnoyarsk and 75.20% [95%CI=69.90.80.60%] in Kemerovo. HIV prevalence among sex workers varied from 2.32% [95%CI=0.49.4.17%] in St. Petersburg to 15.01% [95%CI=11.46.18.56%] in Perm. HIV prevalence among MSM ranged from 7.10% [95%CI=4.10.10.10%] in Moscow to 22.80% [95%CI=17.90.27.70%] in St.-Petersburg. Conclusion. The number of new HIV infections estimated by the retrospective cohort method indicated rapid spread of HIV infection among IDUs in all cities except St.-Petersburg, relatively high HIV growth rates among MSM ranging from 1.6% per year [95%CI=0.1... 3.1%] to 4.6% per year [95%CI=0.0... 11%] and 12.3% annual HIV growth rate [95%CI=0.0... 28.3%] among sex workers. Generally, the situation in the studied groups remained adverse and called for more intensive prevention activities in vulnerable populations.

In examining the strikingly high prevalence rates of HIV in many parts of Africa, reaching as high as 5% in some areas, how does the discourse promoted by the predominant religions across the continent, Islam and Christianity, affect the outlook of their followers on the epidemic? This question becomes even more intriguing after discovering the dramatic difference in rate of HIV prevalence between Muslims and Christians in Africa, confirmed by studies that have found a negative relationship to exist between HIV prevalence and being Muslim in Africa, even in Sub-Saharan African nations. Why does this gap in prevalence rates exist? Does Islam advocate participating in less risky behavior more so than Christianity? By comparing the social construction, epidemiological understanding and public responses among Muslim populations in Africa with Christian ones, it becomes apparent that many similarities exist between the two regarding discourse and that, rather than religious discourse itself, other social factors, such as circumcision practices, contribute more to the disparity in HIV prevalence than originally thought.
