There have been many predictions, mostly based on guesswork, that India's AIDS problem will explode -- as it did in southern Africa -- but we now have direct evidence of something positive. The good news is that HIV in young adults appears to be declining in the south -- most likely or perhaps only due to men keeping away from (sex workers) or using condoms more often when they do. The not-so-good news is that trends in the north remain uncertain and poorly studied.
