Task: Answer Verification
Input (English): Question: Is hIV-1 viral replication below 50 copies/ml in patients on antiretroviral therapy associated with CD8+ T-cell activation?
Answer: T-cell activation in patients on long-term successful ART is not due to residual low-level viral replication in the blood compartment of HIV-1. CD8+ T-cell activation in this patient group appears to be associated with poor CD4+ T-cell recovery.
Output (English): no
