Quick Answer
Most HPV infections clear naturally within 1-2 years. The immune system suppresses the virus without treatment in ~90% of cases. Persistent high-risk HPV (lasting >2 years) is the main concern because it can progress to precancerous cervical changes.
- Clearance rate: 90% of HPV infections clear within 2 years
- Persistence: high-risk strains (HPV 16, 18) are more likely to persist
- Smoking doubles the risk of HPV persistence
- Screening: Pap smears detect cervical changes from persistent HPV

The natural history of HPV is the reason most people never know they had it. The immune system handles it without intervention.
Clearance Timeline
Most HPV infections are cleared within 6-12 months. By 2 years, 90% are gone. Persistent infections beyond 2 years warrant closer monitoring.
