HPV is spread by direct or indirect contact. It can resist desiccation, freezing, and prolonged storage outside of host cells. Autoinoculation also may occur, causing local spread of lesions. The incubation period for HPV ranges from 1-6 months; however, latency periods of up to 3 years or more are suspected.
