HIV TESTING• Reduce HIV-related
morbidity and mortality
• May minimize high-risk behaviour
• Provide linkages to HIV treatment and care services

BARRIERS TO HIV TESTING IN THAILAND• Uptake of HIV testing <20% among IDU in Asia-Pacific
• 2003 “War on Drugs” campaign
• Fear of HIV-positive test result
• Stigma and discrimination
• Breaches of patient confidentiality

MITSAMPAN COMMUNITY RESEARCH PROJECT• A collaborative research effort involving:
• Peer researchers involved in all stages of the project• Former/active drug users trained as peer researchers
Interviewers Outreach workers
• Three completed cycles to date (2008, 2009, 2011)

DISCUSSION• Substantial proportion willing to get peer-delivered VCT
at a drug user-run drop-in centre
• Peer-delivered VCT could reach key groups who may be missed through traditional public health methods IDU who were previously incarcerated IDU engaged in high intensity drug use
• Need for HIV prevention education efforts for IDU Increase awareness of HIV risks and transmission Target IDU with lower education and those who avoid HIV tests

CONCLUSION• Current HIV testing approaches in Thailand are
limited• Need for ongoing HIV prevention education efforts• Potential of novel approaches to VCT for IDU
