Rapporteur report

Track C report by Anne BUVÉ

In this session, six presentations were done to describe the epidemiology and trends of HIV infection among high-risk populations as well as in young people. In the Philippines (TUC0201), behavioural and serological surveys have been conducted in 2005, 2007 and 2009 among female sex workers, MSM and IDU in 10 sentinel sites nationwide. This study showed high level of knowledge, increasing condom use while at the same time rising trends in HIV prevalence. This trend is of major concern and indicates the importance of effective interventions targeted at these populations. Similarly, data from Thailand show increasing incidence of HIV among royal Thai army conscripts between 2005 and 2009 ((TUAC0202) and among MSM between 2003 and 2009, particularly those below 22 years of age (TUAC0203). In Brazil, a national survey conducted to provide baseline HIV prevalence among MSM reported HIV prevalence of 12.6% (TUAC0206), although 75% of men in this study perceived themselves to be at low risk of HIV. These studies highlight the importance of targeting high-risk groups in the prevention programmes in these countries. Results from a UNAIDS study conducted to analyse changes in HIV prevelance and sexual behaviors among young people (15-24 years) in 21 countries in Africa and the Caribbean provided more encouraging news (TUAC0204). HIV prevalence among young people has been declining in the majority of countries, accompanied by adoption of safer sexual behaviors. This is possibly associated with declining HIV incidence as a result of prevention programmes. In another study which involved a meta-analysis involving more than 13,000 discordant couples in sub-Saharan Africa (TUAC0205), it was reported that females were as likely as men to be the index clients in a relationship, suggesting that the likelihood of being firstly infected by HIV was the same between men and women in stable relationships.
