“…`genital types') and typically transmitted via sexual intercourse, whereas the beta, gamma, mu and nu HPV preferentially infect skin (i.e. `cutaneous types') and are transmitted non-sexually, likely via fomites at sites of local epithelial micro-trauma [2]. The approximately forty genital HPV of the genus alpha are divided by oncogenicity into two groups: low-risk types (lrHPV such as genotypes −6,−11,−40,−42,−43,−44,−53,−54,−51,−72,−73,−81) which are isolated from benign genital warts, and 15 or so high-risk types (hr HPV, notably genotypes 16,−18,−31,−33,−35,−45,−51,−52,−56,−58,−59,−68) that are detected in cervical cancer [3].…”
