  • HPV infects basal keratinocytes
  • Common sites of inoculation include swimming pools
  • Incubation period for warts is 1 to 24 months, with warts appearing in different locations
  • Warts are categorized based on location, e.g., common warts, plantar warts and flat warts

Wart Objectives

  • Describe symptoms related to warts
  • Identify signs of inappropriate self-care
