the already existing legal framework is sufficient to cover all cases of malevolent transmission of HIV/AIDS, and an additional, HIV specific law is unnecessary.

As I was reading, that is what I was wondering - was it HIV specific laws or general laws being used to prosecute?  I too don't see the need for specific legislation on the transmission of HIV for that reason, any deliberate act of harm to another person is already covered by criminal law.

To further stigmatise HIV with separate legislation is as you say so counterproductive.  People can't seek help and advice when they are afraid to be checked or to discuss the issue with anyone.

Thanks for the diary, Nomad - it is always good to raise the profile of issues like this.
