New Scientist;3/5/2005, Vol. 185 Issue 2489, p20
The article focuses on the new research findings in HIV infection. Different variants of HIV are passed from men to women than those that go from women to men, according to researcher Oliver Laeyendecker of the U.S. National Institute of Allergy and Infectious Diseases in Bethesda, Maryland. Laeyendecker team's finding is based on a small study of 10 couples in Uganda. The team compared the HIV variants in each partner to determine which were passed on. During sexual transmission, the virus goes through an evolutionary bottleneck.
