title: Why HIV-1 has diffused so much more rapidly in Sub-Saharan Africa than in North America.
abstract: AIDS was first identified in Sub-Saharan Africa and North America in the early 1980s. Over the past twenty years, however, HIV-1 has diffused much more rapidly in the former continent than in latter. This appears to be because the virus cannot diffuse well in local populations that have an adequate dietary intake of selenium.
