Well Steve, I also gave you MY solution, which happens to also be the solution being "looked at" by HPA and CDC.

The only problem is they cannot say what they mean directly because of "rights/anti discrimination legislation."

In the developed countries, hiv/ aids has become mainly a disease of one "at risk" group,   MSM.

All other demographics have very low rates of infection and these rates are falling, while infection rates in MSM are very high and rising steadily.....this is not homophobia, but incontravertible fact.

I would first instigate a public enquiry to determine why infection rates are so high in this particular demographic, then start compulsory testing and contact tracing in at risk groups with high infection rates.
To test everyone in a given geographical area, regardless of their demographic is almost unworkable, too expensive and unlikely to be effective.

I would also ensure that the full facts regarding hiv was presented to the public. This is a serious issue and concealment....as seems to be favoured by most people will serve no one well....especially male homosexuals
