Document Summary
The scale of asia"s epidemic has more to do with the size of the continent"s population than the explosive spread of the virus. A low prevalence rate in a large country can spell disaster. One or two percent of the indian or chinese populations is an enormous number of people, The major difference when you compare the african and asian epidemic is the speed. There are subnational epidemics at 5% prevalence or more going on, and we"re ignoring this because of low national prevalence overall. Whether the epidemic in asia follows the path chin predicts or one that more closely resembles an african epidemic rests largely on the rate of spread in the general population by heterosexual sex. From all behavioral studies, there"s a big difference in the number of partners that men and women in asia report having, and that"s not true in africa.
