Honing the Test-and-Treat HIV Strategy

摘要

In his news focus story ("treatment as prevention," 5 March, p. 1196), J. Cohen reviews ideas presented at the 17th Conference on Retroviruses and Opportunistic Infections about the use of HIV treatment as prevention. Enthusiasm for the treatment-as-prevention approach has grown in recent years as (ⅰ) the drugs have become safer, better tolerated, and more widely available; (ⅱ) widespread testing has become cheaper and more efficient; (ⅲ) earlier therapy has become desirable; and (ⅳ) mathematical modeling by some (1) (but by no means all) has suggested that a test-and-treat strategy could control the spread of HIV.
