VIRAL VICTOR

摘要

In March, Deborah Persaud was ready to share the news: a baby born with HIV in Mississippi seemed to be virus-free nearly a year after stopping treatment. Persaud, a serious, soft-spoken virologist at Johns Hopkins Children's Center in Baltimore, Maryland, says she knew that she had to tread delicately. More than 40 similar cases had previously been reported in the literature, and each had fallen apart on closer scrutiny. Genetic analysis revealed that most of the initial tests had generated false positives or had involved specimen mix-ups.
