2004 Update Thailand Page - 2 Thailand HIV/AIDS estimates In 2003 and during the first quarter of 2004, UNAIDS and WHO worked closely with national governments and UNAIDS/WHO Working Group on Global research institutions to recalculate current estimates on people living with HIV/AIDS. These calculations are based on the previously published estimates for 1999 and 2001 and recent trends in HIV/AIDS surveillance in HIV/AIDS and STI Surveillance various populations. A methodology developed in collaboration with an international group of Global Surveillance of HIV/AIDS and sexually experts was used to calculate the new estimates on prevalence and incidence of HIV and AIDS deaths, as well transmitted infections (STIs) is a joint effort of as the number of children infected through mother-to-child transmission of HIV. Different approaches were WHO and UNAIDS. The UNAIDS/WHO Working Group on used to estimate HIV prevalence in countries with low-level, concentrated or generalised epidemics. The Global HIV/AIDS and STI Surveillance, initiated in November current estimates do not claim to be an exact count of infections. Rather, they use a methodology that has thus 1996, guides respective activities. The primary objective of the far proved accurate in producing estimates that give a good indication of the magnitude of the epidemic in Working Group is to strengthen national, regional and global individual countries. However, these estimates are constantly being revised as countries improve their structures and networks for improved monitoring and surveillance systems and collect more information. surveillance of HIV/AIDS and STIs. For this purpose, the Working Group collaborates closely with national AIDS Adults in this report are defined as women and men aged 15 to 49. This age range covers people in their most programmes and a number of national and international experts sexually active years. While the risk of HIV infection obviously continues beyond the age of 50, the vast and institutions. The goal of this collaboration is to compile the majority of those who engage in substantial risk behaviours are likely to be infected by this age. The 15 to 49 best information available and to improve the quality of data range was used as the denominator in calculating adult HIV prevalence. needed for informed decision-making and planning at national, regional, and global levels. The Epidemiological Fact Sheets are Estimated number of adults and children living with HIV/AIDS, end of 2003 one of the products of this close and fruitful collaboration across the globe. These estimates include all people with HIV infection, whether or not they have developed symptoms of AIDS, alive at the end of 2003: Within this framework, the Fact Sheets collate the most recent country-specific data on HIV/AIDS prevalence and incidence, Adults and children 570,000 together with information on behaviours (e.g. casual sex and Low estimate 310,000 High estimate 1,000,000 condom use) which can spur or stem the transmission of HIV.

Therefore, the Working Group Deaths in 2003 58,000 Low estimate 34,000 would like to encourage all programme managers as well as High estimate 97,000 national and international experts to communicate additional information to them whenever such information becomes Estimated number of orphans available.

While the early AIDS cases were reported predominantly among Thai homosexual males, subsequently, the virus spread rapidly to injecting drug users, and to sex workers and their clients. As of January 2004, 231,712 AIDS cases have been reported, of whom nearly 80% were in the age group 20-39 years. The male-to-female ratio of reported AIDS cases is 2.8:1. Of the AIDS cases reported to date with a known route of transmission, heterosexual mode accounts for the highest proportion of cases (88%), followed by injecting drug use (6%) and perinatal transmission (5%). Data from a comprehensive sentinel surveillance system indicate that the HIV prevalence among pregnant women, after reaching a peak of 2.35% in 1995, has consistently declined in the past five years to reach 1.18% in 2003. Nationally, HIV prevalence among military conscripts decreased markedly from 4% in 1993 to 0.5% in 2003. Among commercial sex workers, HIV prevalence peaked in the mid-nineties and has constantly declined since then. The HIV prevalence among injecting drug users, however, remains high at 33% in 2003 and poses a major challenges to HIV control in Thailand. The HIV prevalence among the other high risk groups in 2003 was: female direct sex workers (10.87%); male sex workers (7.90%), fishermen (6.86%); male STD clients (4.00%); female indirect sex workers (3.67%); and blood donors (0.27%). At the end of 2003, an estimated 1.7% of the adult Thai population aged 15-49 years was infected with HIV. The estimated number of PLWHAs at the end of 2003 was 570,000. Although Thailand has achieved substantial success in HIV control with the annual number of new HIV infections dropping from 142,819 in 1991 to 21,260 in 2003, the AIDS crisis will continue to grow as the large number of PLWHAs who were infected during the past 10 years or earlier will develop AIDS in the coming years. According to projections for the next five years, nearly 50,000 new AIDS cases will occur in Thailand every year. To address the needs of the PLWHAs, the Thai government has been expanding its antiretroviral programme since 2000. Currently, approximately 13,000 PLWHAs are on antiretroviral therapy. The government has committed to the goal of universal access to care and has allocated 25 million US dollars in fiscal year 2004 to scale up access to ARV to 50,000 PLWHAs.
