Most people with a healthy immune system will eventually clear a high-risk HPV infection (test negative). Around four out of every ten people (40%) affected by a high-risk HPV infection will clear it within 12 months (one year) and this increases to around six out of every ten people (60%) within two years . However, in a minority of people an infection can persist over many years and may result in recurrent abnormalities (though this is rare).
