There are more than 170 different strains of the human papillomavirus (HPV) and each of the strains prefer to grow on different parts of the skin (Anchor Study, 2021; Chen et al., 2016).
Only 40 kinds of HPV infect the genital area; including the vulva, vagina, cervix, rectum, anus, penis, and scrotum, as well as the mouth and throat (Ebrahim et al., 2016). These kinds of HPV are spread during sexual contact (Ebrahim et al., 2016).
However, there are many types of HPV that are not sexually transmitted. These types of HPV cause common warts, such as hand warts and plantar warts on the feet (Anchor Study, 2021). HPV is so common that everyone has been exposed to the virus at some point, some people are simply more likely to get warts than others (Anchor Study, 2021).
