Indonesia's National AIDS Prevention Commission says 12 children it found living with HIV/AIDS in the Jayapura district of Papua, are just the tip of the iceberg.
The results of a survey conducted in Sentani in Jayapura last year have just been made public.
The Commission's secretary Purnomo says the children contracted HIV from their mothers during childbirth and breastfeeding.
He says preventive measures need to be taken by the community to stop the spread of the disease.
The survey showed the total number of reported cases of people with HIV in Jayapura regency reached 609 in 2010, with 367 of these being women.
