Indonesia's first case of HIV was reported in 1987 and between then and 2009, 3,492 people died from the disease. Of the 11,856 cases reported in 2008, 6,962 of them were people under 30 years of age, including 55 infants under 1 year old. There were a high number of concentrated cases among Indonesia's most at risk including
injection drug users (IDUs),
sex workers their partners and clients, homosexual men and infants who contract the disease through the womb or from being breast fed. UNAIDS has also estimated there were 110,000 orphans due to AIDS aged 0 to 17 in 2015. According to 2016 data from the
Ministry of Health, risky heterosexual sex is attributed to 47% of new HIV infections, MSM accounted for 25% and the cohort 'under 4 years old' accounted for 2%. When these three are combined it equals almost 75% of all new HIV infections. Historically the highest concentration areas have been
Papua,
Jakarta,
East Java,
West Java,
Bali and
Riau. The island of Java, which includes the capital Jakarta, is now home to the highest concentration of HIV cases in Indonesia. Of the 34 provinces spread across the vast territories of Indonesia, two provinces represent more than a quarter (28%) of the national total of people living with HIV – DKI Jakarta and Papua. A generalised epidemic was already under way in the provinces of
Papua and
West Papua, where a population-based survey found an adult-prevalence rate of 2.4% in 2006. When surveyed, 48% of Papuans were unaware of HIV/AIDS, and the number of AIDS cases per 100,000 people in the two provinces was almost 20 times the national average. The percentage of people who reported being unaware of HIV/AIDS increases to 74% among un
educated populations in the region. The
epidemic in Indonesia is one of the fastest growing among
HIV/AIDS in Asia. In 2006 it was considered that injecting drug use was the primary mode of transmission, not heterosexual sex. Injecting drug users accounted for 59% of HIV infections, and heterosexual transmission accounted for 41% . According to the Indonesian Ministry of Health, surveys reported that more than 40% of injecting drug users in
Jakarta tested positive for HIV, and about 13% tested positive in West Java. In 2005, 25% of IDUs in
Bandung, Jakarta, and
Medan said they had unprotected paid sex in the last 12 months. This shows there were an estimated 697,000 people living with HIV in Indonesia in 2016. This is projected to increase by 11.6% to almost 778,000 in 2019. This increase is far above the anticipated natural population growth rate of 3.6% over the same period (World Bank 2016). This modelling also highlights that the largest key population when measured by total projected new infections, and by the total number living with HIV, is low risk women. HIV-positive men aged over 15 years (420,000) outnumber women in the same age cohort (247,000) at a ratio of almost 2 to 1 according to PEPFAR (2016). According to the National AIDS Commission of Indonesia "the annual number of new ART initiators continues to fall short of the estimated annual number of new HIV infections, and insufficient treatment retention rates limits both the prevention and mortality impact of resources being spent on HIV treatment. The strategies being employed to contain HIV in Indonesia are by and large appropriate given the stage of the HIV epidemic, but have not been realizing their full impact due to insufficient scale and program implementation issues". ==Challenges of addressing HIV/AIDS in Indonesia==
