HIV evolving 'into milder form'

The BBC News site is reporting a study by virologists at Oxford University which suggests that the HIV virus is evolving to become less deadly and less infectious.

To paraphrase an article, which itself paraphrases a much larger study, every so often HIV infects someone with a particularly effective immune system and has to adapt if it is to survive, which it does so at a cost to its ability to replicate.

Whilst this is far from a sign that HIV is about to become ineffective yet, it's good news, particularly given the additional factor that retro-viral drugs are forcing HIV to become milder and take longer to develop into AIDS.
