I would also add East Asia (China, Japan, South Korea, Taiwan, Hongkong, Macao) to that list. The rate of HIV positive ("seropositive") status is still incredibly low. Ignore China for a moment because it is hard to believe any of their official gov't stats! These countries are definitely much more sexually active (more lifetime partners) than more socially conservative neighbors in South Asia (Indian subcontinent).

Interestingly, in these countries, there is still ready access to sex workers in any medium-sized city and above, yet infection rates are still very low.

I must confess: I wrote the above post strictly about heterosexuals. I have never read anything seropositive rates for gay men in these regions. (I write the last sentence with the assumption that gay women have a tiny risk to contract and spread HIV.)
