Dave, you are right in stating that I am no expert, but there are very many viruses for which there are no cure, not just HIV.
HIV/AIDS is a very serious illness causing death or at best, lifetime medication and health care; as this is the case, we need to concentrate on curtailing transmission rates until a "cure" may be found.

There is no cure for cancer, so we enforce rules to stop the disease developing. like the anti smoking laws etc.

I think Jack may have a point, in that these things should be self evident, and you keep asking questions which are not really relevant to the issue.

It is not my job to work out ways of enforcing responsible behaviour in male homosexuals.....but there is certainly a need to do so.
