With therapy, viral loads can often be suppressed to an undetectable level (ie, < 20-75 copies/mL, depending on the assay used); this is considered optimal viral suppression. At the same time, the CD4 count rises and the risk of opportunistic infections and death is reduced. Complete inhibition of viral replication appears impossible and may be unnecessary.
