AIDS Researchers Look to Africa for New Insights

摘要

San Francisco, California—A remarkable shift in emphasis occurred here last week at the largest annual AIDS meeting held in the United States. Instead of reports from North America and Europe once again dominating the meeting, many of the most significant findings came from Africa, where 70% of the world's 33 million HIV-infected people live. As HIV infection rates have plateaued in most developed countries, investigators are increasingly turning to Africa, where the epidemic is still exploding. "When it moves that rapidly, there are many things you can do about it," explains Anthony Fauci, head of the U.S. National Institute of Allergy and Infectious Diseases (NIAID).
