  26. From: Pattarakulwanich S, Thai Ministry of Public Health

  27. Thailand prevented millions of AIDS death

  28. From: Pattarakulwanich S, Thai Ministry of Public Health

  29. Outline: Use the HIV/AIDS epidemic to demonstrate how RESEARCH help form EVIDENCE-BASED PUBLIC HEALTH POLICY in Thailand The Thai epidemic in relation to the world’s Thailand’s success from the beginning of the epidemic until 2551 Commercial sex workers PMTCT Access to HAART Thailand’s remaining problem areas: IDU, MSM, Youth (and low usage of VCT) LESSONS LEARNED for กรมควบคุมโรค

  30. Injecting drug use in Thailand The actual number of users who inject drugs is not known Estimates range from 100,000 to 250,000 addicts Most of them are males (around 90 percent) and mostly aged between 20-24 years From: Khondkar L, Tackling HIV/AIDS among Thai IDU (www.aids2006.org/Web/TUAE0103.ppt)

  31. HIV/AIDS among IDUs About one quarter of all new infections is occurring through unsafe injecting drug use Median HIV prevalence among IDUs is as high as 50% HIV is a major killer of IDUs in Thailand The situation has remained consistent for nearly 15 years The high prevalence is due to the frequency of injecting, widespread sharing of needles, and imprisonment of IDUs From: Khondkar L, Tackling HIV/AIDS among Thai IDU (www.aids2006.org/Web/TUAE0103.ppt)

  32. Limitations in addressing HIV/AIDS among IDUs Little collaboration between drug control programs and HIV/AIDS response Narcotic Control legislation does not pay attention to the prevention of HIV among IDUs Lack of communication between AIDS control authorities, Office of Narcotics Control Board, and those working in drug treatment Technical skills are not very high in addressing HIV/AIDS among drug users From: Khondkar L, Tackling HIV/AIDS among Thai IDU (www.aids2006.org/Web/TUAE0103.ppt)

  33. Summarizing the challenges Criminal justice approach taken by government Non-availability of harm reduction programs Limited prevention coverage Ineffective treatment interventions Discriminatory practices in society and health care facilities Lack of opportunity for IDUs to take part in decision making process affecting them From: Khondkar L, Tackling HIV/AIDS among Thai IDU (www.aids2006.org/Web/TUAE0103.ppt)

  34. HIV prevalence among MSM – Bangkok From: Thai MOPH, U.S. CDC, Thai Red Cross, Family Health International, and Purple Sky

  35. HIV in Thai teenagers 2001 HIV positive 7.1 % 2002 HIV positive 7.9 % 2003 HIV positive 13.6 % Anonymous clinic : Thai Red Cross, Bangkok

  36. Casual sex For male group, the value changed from 5% in 1996 to 20% in 2004 For the female, the value changed from 2% in 1996 to 10% in 2004 From: Peerapatanapokin W, Thai MOPH

  37. Outline: Use the HIV/AIDS epidemic to demonstrate how RESEARCH help form EVIDENCE-BASED PUBLIC HEALTH POLICY in Thailand The Thai epidemic in relation to the world’s Thailand’s success from the beginning of the epidemic until 2551 Commercial sex workers PMTCT Access to HAART Thailand’s remaining problem areas: IDU, MSM, Youth (and low usage of VCT) LESSONS LEARNED for กรมควบคุมโรค

  38. Lessons learned for กรมควบคุมโรค (1): Use past success as a guidance,even in the new role as an “academic” Department Many “facts/evidences” have already been published Identify specific “gaps” that the Department has to do research to guide MOPH policies

  39. Lessons learned for กรมควบคุมโรค (2) : Research should be “need-driven” NOT “investigator-driven” The Department needs “block grant” NOT grant for individual proposaland needs to set specific themes and objectives identified as MOPH priorities

  40. Thank you
