I used to know a guy who worked in Zimbabwe before our government finally fell out with Mugabe. He told how HIV was non existant there until the Health Minister died from Aids.
I used to find Indian culture very 'Victorian' it all happened but no one ever spoke about it or acknowledged it wqas happening. The problem is that they are people just like us and do the very same things we do. It used to be the case that you could not get a work permit without an aids test, but tourist visas were sold to any one who wanted one and certain parts of India are very popular with tourists, and of course the locals will provide the required facilities for these tourists to help them spend their hard currency. So th original Indian idea of a 'fortress against aids was doomed.
The real problem is that endemic aids in India will make Africa look like a minor outbreak, remeber the Indian population currently is the same as China give or take the odd million.
