Transmission of Genital Human Papillomavirus Infections is Unlikely through the Floor and Seats of Humid Dwellings in Countries of High-Level Hygiene

Abstract

To evaluate the transmission of genital human papillomavirus (HPV) through the floor and seats of humid dwellings, samples were collected with a toothbrush from the floor and seat surfaces of humid dwellings; showers, saunas and dressing rooms. The survey included 3 bathing resorts, 1 indoor swimming pool, 2 schools and 2 private homes. Polymerase chain reaction (PCR) was used to amplify the human beta-globin gene and HPV DNA. The results for HPV DNA amplification were confirmed by Southern blot hybridization under low stringency using a probe mixture of HPV types 6, 16, 18 and 31. beta-globin could be amplified only from 3 sample taken from a dressing room of and indoor public swimming pool. No HPV DNA-positive samples were found. These results indicate that transmission of genital HPV infection via floor or seat surfaces in the above dwellings in general or family use is highly unlikely.

Human Papillomavirus Infections in Children: the Potential Role of Maternal Transmission

“…In an additional 11 mothers, genital infection with the same HPV type as in the child was diagnosed a few months before or after delivery. One child had an oral papilloma where HPV 16 was detected, a type that was also found in her mother's genital mucosa (Puranen et al, 1996b). These results support the concept that an infected mother can transmit HPV to her child, and that this infection can persist for years.…”

“…No HPV DNA-positive sample was found. Our results indicate that transmission of genital HPV infection via floor or seat surfaces on the above premises is highly unlikely (Puranen et al, 1996b). (4.2) SEXUAL ABUSE In contrast to the unequivocal data on sexual transmission of genital warts in adults and sexually active adolescents, reports on the primary mode of transmission of genital warts in children have been more contradictory (Gutman et al, 1992). In children, the issue of genital warts originating from sexual abuse was raised in the 1980s, when vulvar condylomata in young children, previously considered extremely rare, were reported with increasing frequency (Stumpf, 1980).…”

“…We recently obtained similar data in a series of 98 children (0.3 to 11.6 years of age) born to mothers included in our prospective cohort of 530 women (Puranen et al, 1996b). Our evaluations included medical history, clinical examination of the oral cavity and hand warts, as well as cytological samples from the oral mucosa for HPV detection by PCR and subsequent Southern blot hybridization (SBH).…”

Papillomavirus humain (HPV) : comment ai-je attrapé ça ?

“…Ce taux de transmission serait plus é levé lors des accouchements voie basse que lors des cé sariennes et ce quel que soit le type d'HPV [45]. Le taux de concordance des gé notypes HPV varierait entre 70 et 91 % [45,[48][49][50]. On explique les discordances par des infections multiples à HPV avec un HPV pré sent dans le vagin pouvant être diffé rent de celui pré sent dans la cavité uté rine ou par une contamination de l'oeuf par le sperme infecté lors de la fé condation.…”

Anogenital Warts in Children and Sexual Abuse

“…Prepubertal çocuklarda HPV geçişinde birçok potansiyel yol tanımlan-mıştır: perinatal geçiş, oto veya hetero inokülasyon, cinsel istismar ve fomitler [9][10][11][12][13]. Çocuklarda cinsel istismar sonucu genital siğillerin ortaya çıka-bileceği, ilk kez 1980 yıllarında çocuklarda vulvar kondilom insidansındaki artış sonucu ortaya çıkmıştır [14].…”
