...They are the reason Dr. David Ho has come to China. The New York City-based virologist was named TIME's 1996 Person of the Year for his pioneering work on the drug therapies that have largely quelled the AIDS epidemic in the U.S. and Europe. Now Ho is confronting the AIDS virus in its most populous stronghold. Up to 1 million Chinese are HIV positive, and that number could easily grow to 10 million by 2010, according to the Joint U.N. Program on AIDS. If current trends continue for another decade or so, China could overtake Africa, where...
...Asia, there is no program in place to systematically sample migratory birds to determine which viruses they carry. In Europe, virologist Albert Osterhaus of Erasmus University in the Netherlands has launched a survey in which fecal samples are submitted from around the continent for testing.

Even after the genetic sequences had arrived, his peers were unconvinced. "When someone is showing you raw data, you have to be careful," said Dr. Xu Ruiheng, deputy director of the Guangdong CDC. "You have to ask yourself, is this real or is this fabricated?" In turn, Yi asked his counterparts if they had the sequences for the human patient now recovering in Guangzhou...
