A study of 130 middle-aged and older African-American men found that many engaged in high-risk sexual practices without using condoms. The research also showed that men who were single and displayed fewer HIV symptoms were least likely to use condoms during sex, with 78% able to answer questions about HIV and AIDS correctly.
A new study suggests that a lack of HIV prevention dollars for male sex workers in the Caribbean is fuelling the region's AIDS epidemic. The study found that bisexual behaviour among these men can significantly contribute to the spread of HIV.

Researchers propose that host/virus co-adaptation enables monkeys to limit T cell immune activation and apoptosis, a mechanism that contributes to disease progression.
A study of HIV-infected women found that pregnancy can actually slow disease progression, not accelerate it. The use of HAART during pregnancy significantly reduces the risk of transmitting the virus to the child, and pregnant women tend to have lower risks of disease progression before and after pregnancy.
Dr. Anthony S. Fauci has been recognized for his role in developing the President’s Emergency Plan for AIDS Relief (PEPFAR) and Project Bioshield, two major U.S. public health programs. He has made significant contributions to understanding AIDS pathogenesis and has advised several administrations on global HIV/AIDS issues.
