The number of known HIV/AIDS cases in Indonesia has almost tripled since 2005, AIDS commission head Nafsiah Mboi said Wednesday.
There were 26,632 HIV/AIDS cases in March, up from 9,565 in 2005, she said.
The actual number of people with the disease was far higher as 85 percent of sufferers did not know they were infected, she said.
"The number of infections is increasing and it's worrying," Mboi added.
Representatives from more than 60 countries from around Asia and the Pacific will gather in Bali in August to discuss joint efforts to prevent the spread of the disease.
