Regular screening of infectious diseases among drug users in treatment settings andcollecting these data for surveillance practices is not common practice in the Netherlands. In Amsterdam, the Municipal Health Services (GGD) runs most of the methadonetreatment locations. As part of the treatment, patients are tested regularly for drugrelated infectious diseases. For the methodology used, see Standard Table 09 (ST09).In 2009, 46 IDUs were tested for HIV antibodies; none had a positive test result. In Rotterdam the project “Active Testing” was piloted in 2007 and 2008. The projectaims to offer and actively support the whole chain from counselling and testing totreatment completion for problematic drug users and homeless people. In 2009 theproject was in a transitional phase towards regular imbedding in addiction care facilitiesin Rotterdam. Due to this transition, there are no new data available for the year2009.6.1.2 AIDSUntil 2001, AIDS cases meeting WHO criteria were registered in the national InformationSystem on AIDS Statistics, maintained by the Health Care Inspectorate (IGZ). In 2002this AIDS registration was replaced by the HIV/ AIDS registration of the SHM mentionedabove. As the IGZ data appeared to be incomplete since 2000, the data below are basedon the IGZ registration until 1999 and the SHM data from 2000 onwards. The year ofAIDS diagnosis refers to the date of the first CDC-C diagnosis (classification C accordingto the Centres for Disease Control). Up to December 2009, the cumulative total of reported AIDS diagnoses was 8,059and 4,947 HIV infected individuals had died (Vriend et al., 2010). The annual numberof new AIDS diagnoses peaked in the first half of the nineties (around 500 cases peryear) and then gradually dropped, to 168 cases in 2009 (Vriend et al., 2010). The observeddecrease since 1996 is related to the availability of HAART, which slowed progressionfrom HIV to AIDS.83
