Hi there...unfortunately hpv can spread through contact. Kindly refrain from any sexual activity till the lesions are completely healed. Hpv virus can remain subclinical and recurrences can occur. Since it is asymptomatic, examine your genitals and hands regularly for new lesions. try to use barrier protection methods like condoms when ever possible. For any further queries you can consult a dermatologist. Treatment is mainly through application of podophyllum paint. It should be applied by the dermatologist only, as it is a very corrosive agent
