The Netherlands Drug Situation 2010 - Trimbos-instituut

In 2009, 692 new HIV diagnoses were reported in the treatment centres. In 1 maleand 0 women (0.1%) injecting drug use was the most likely route of transmission(table 6.1) (Vriend et al., 2010).Up to December 2009 a cumulative total of 16,555 HIV-infected individuals were registeredby the treatment centres and the HIV Monitoring Foundation (Vriend et al.,2010). The percentage of patients infected with HIV through injecting drug use is 4%(675 patients). The main route of HIV-transmission in the Netherlands is sexual:through MSM contact in 55% of cases and through heterosexual contact in 32%.42% of all injecting drug users were diagnosed with HIV at an age between 30 and39 years. IDUs were on average younger than MSM and heterosexuals: the diagnosiswas made before 39 years of age in 78% of IDUs, against only 63% of the diagnosesin MSM and 72% of heterosexuals diagnosed before this age (Vriend et al., 2010)(Figure 6.1).Of the registered HIV positive injecting drug users, almost three quarters originatedfrom the Netherlands and 22% from other Western European countries. This is insharp contrast to HIV-positives infected through heterosexual contact, of whom onlyone third had a Dutch origin and almost half originated from Sub-Saharan Africa (table6.1) (Vriend et al., 2010).Table 6.1.1: Number and characteristics of recorded HIV infections by route of transmissionTransmissiongroupNumber andpercentage ofHIV casesdiagnosed in2009Cumulativenumber andpercentage ofHIV casesGender: percentagemales (ofcumulativenumber intransmissiongroup)Region of origin:percentagefrom the Netherlands(of cumulativenumber)MSM 534 (66%) 9,132 (55%) 100% 84%Heterosexual223 (28%) 5,294 (32%)contact43%34%Injecting drug1 (0.1%) 675 (4%)use73%72%Blood (products)*2 (0.2%) 229 (1%) 64% 56%Mother to child4 (0.5%) 183 (1%) 52% 57%Other/ unknown48 (6%) 1,042 (6%) 83% 54%Total 812(100%) 16,555 (100%) 79% 65%* Including needle stick injuries.
