The chair of Papua New Guinea's parliamentary HIV/AIDS committee, Dr Banare Bun, says young people intending to marry should undergo compulsory blood tests.
The Post Courier newspaper reports Dr Bun saying those with the highest infection rate are in the 13 to 31 age group and compusory tests would help reduce the predicted rise in infection.
That rise could see 20 per cent of the population infected in the next ten years.
Dr Bun says a lot of young people are running around with the disease and could pass it on to their partners when they marry.
He also called on young people to avoid pre-marital sex.
