This is necessary because the virus enters through a disrupted epithelial barrier and infects replicating basal keratinocytes; it then relies on the differentiation of the keratinocytes to reach the surface and be shed for continued infection. The virus replicates only during terminal differentiation of the superficial keratinocytes, which allows it to be shed into the mucosal lumen. The superficial keratinocytes ultimately are shed with the stratum corneum, so no lytic phase exists in the HPV life cycle, as the apoptotic keratinocytes release the virus during degradation in the mucosal lumen (see the image below).
