Estimating HIV Prevalence in Malaysia Method Multi-parameter evidence synthesis methods were applied to combine all available relevant data sources Results An estimated 454,000 (95% [CrI]: 392,000 to 535,000) HCV Ab positive individuals were living in Malaysia in % of the adult population Route of probable transmission - active or a previous history of IDU Females represented 1% (95% CrI: 0.6 to 1.4%) of all HCV infections, 92% (95% CrI: 88 to 95%) were attributable to non-drug injecting routes of transmission SA McDonald, A Kamarulzaman et al.

Multiple Barriers at Multiple Steps of the Continuum of Care Adapted from G. Matthews
Barriers to HCV Treatment in Low/Middle Income Countries Lack of Awareness Late Diagnosis Poor Treatment Literacy Multiple Comorbidities – TB Lack of Access to OST Limited Range of ARVs
Treating HCV in Resource-Poor Settings CID 2012:54 (15 May) d 1465
Lessons from HIV Reducing Cost of Treatment Simplifying Model of Care Service Integration Task Shifting Surveillance, Evaluation and Research Patient & Community Engagement Political and Financial Commitment
Overcoming Provider Barriers Easier assessment of the infection and the liver disease 2 -Dry-blood spots (HCV viral load quantification/genotyping) - Portable Fibroscan (Echosens) - Portable sonography Rapid Testing 1 - Point-of-care tests - Salivary rapid testing 1 Yaari A, J Viral Methods Tuaillon E, Hepatology Mostly unavailable in RLS
