In children, even without treatment, 50% of warts disappear within 6 months; 90% are gone in 2 years. They are more persistent in adults but they clear up eventually.
Warts are particularly numerous and troublesome in patients that are immunosuppressed, most often due to medications such as azathioprine or ciclosporin. In these patients, the warts almost never disappear despite treatment.
