WHO/UNAIDS/UNODC comprehensive package includes:
There are effective interventions to prevent HIV and HCV among people who inject drugs WHO/UNAIDS/UNODC comprehensive package includes: Needle and syringe programs (NSP) Opioid substitution therapy (OST) HIV counselling and testing HIV antiretroviral therapy Condom distribution programs

2010: Systematic review reports very poor coverage of these interventions globally

Updated estimates of intervention coverage are needed
Advocacy Policy development Service delivery Aim: to estimate coverage of HIV/HCV prevention interventions for people who inject drugs
8
Approach: Systematic review of published and unpublished literature, with expert consultation
9
Key findings
10
Coverage of NSP has improved, but remains low in most countries
11
Regional and global coverage of NSP
12
Coverage of OST has improved, but remains low in most countries
13
Regional and global coverage of OST
14
Combination high coverage NSP and OST is rare
15
Low coverage of both is most frequent
16
<1% of PWID live in countries with high coverage of both NSP and OST
17
5% of PWID live in countries with either moderate or high coverage of NSP and OST
18
Implications
19
NSP and OST are increasingly implemented
But access to interventions remains poor Coverage insufficient to prevent, halt or reverse HIV and HCV epidemics among people who inject drugs Scale-up of prevention is needed in most countries
20
Better data on program implementation and population sizes are needed
Numerator data not reported in many settings PWID population sizes (denominator) not available in many settings or are very uncertain Other interventions: HCV testing and treatment
