Common association of HPV 2 with anogenital warts in prepubertal children.
Anogenital (AG) warts in 31 prepubertal children were HPV typed by nonisotopic in situ hybridization (NISH) using digoxigenin-labeled probes for human papilloma virus (HPV) types 1-5, 6, 11, 16, 18, 31, and 33. Mode of transmission was determined from historical, clinical, and laboratory data independent of HPV typing. HPV 2 was detected most commonly (13/31 warts) followed by HPV 6 (7/31), HPV 11 (5/31), and HPV 16 (1/31). Although not reaching statistical significance, our results suggested that a mucosal HPV type (6, 11, 16) in a child's AG warts implied transmission from mucosal warts and conversely cutaneous HPV 2 transmission from warts at a cutaneous site. HPV typing provided no helpful information regarding actual mode of transmission of AG warts in these children. The high prevalence of HPV 2 in children's AG warts and the low prevalence of sexual abuse (2 of 31 children) found in this study suggest innocent auto- or heteroinoculation from cutaneous warts may be a common means by which children acquire AG warts.
