AZT vs Traditional FeLV Therapy

Zidovudine (AZT) vs Traditional FeLV Supportive Therapy

Category Traditional FeLV Supportive Therapy Zidovudine (AZT)
Treatment Goal Supportive care: relieve symptoms, maintain immune function, and reduce secondary infections. Antiviral therapy: directly suppress FeLV replication, delaying or reversing disease progression.
Core Concept "Relief + Support" — focuses on complications, without addressing the viral source. "Control + Intervention" — targets the virus itself, aiming to block or clear FeLV activity.
Therapeutic Nature Passive and supportive. Active antiviral action.
Clinical Effect Improves clinical condition but does not affect viral load. Significantly reduces viremia and slows viral replication.
Unlike traditional supportive care, Zidovudine (AZT) directly targets the FeLV virus — addressing the root cause rather than just the symptoms.
