: We use a mathematical model to study the dynamics of HIV-1 replication during structured treatment interruptions (STIs) in infected patients. The model predicts rapid viral rebound, restoration of a latently infected cell pool, and critically, partially resistant mutant rebound that may be missed because of high levels of wild type virus. Because partially resistant viruses are capable of mutating to full resistance, a substantial increase in their numbers represents a threat to therapeutic response durability. Compared with continued treatment, STIs may increase the chance of mutation to full resistance by several thousandfold.
