The nearly 40 types of HPV that have been found in genital warts [14] are highly host-specific. These viruses do not infect laboratory animals and are not susceptible to acyclovir. In addition, HPV types demonstrate a high degree of site specificity, with some types only found on certain parts of the skin or mucous membranes. As a rule, HPV types causing common warts of the skin do not infect moist epithelium, and vice versa.
