인유두종바이러스 감염, 전염, HPV infection, transmission

인유두종바이러스는 감염된 피부와 점막의 접촉을 통해서 전염됩니다. 항문과 회음부의 인유두종바이러스 감염은 거의 항상 성관계를 통해서 획득됩니다. 사마귀가 있어야만 전염되는 것은 아니지만 사마귀가 있으면 아주 전염력이 높습니다. 그 이유는 이곳에 바이러스가 많기 때문입니다.

Human papillomavirus (HPV) is transmitted through contact with infected skin or mucosa. The virus invades the cells of the epidermal basal layer through microabrasions. Anogenital HPV infection is almost always acquired through sexual contact. Warts are not required for transmission but are highly infectious because of their high viral

획득되었을 때에 증상과 징후를 나타내지 않고 잠복기에 들어갈 수 잇으며 보통 잠복기는 3주~8개월입니다.

Once acquired, HPV infection can enter a latent phase without signs or symptoms. In patients who develop CA, the usual incubation period is three weeks to eight months. In a cohort study of 603 female university students that identified 31 students who developed anogenital warts after incident HPV infection, the median time to detection of anogenital warts after detection of HPV 6 or HPV 11 was 2.9 months.

HPV-6 또는 HPV-11 감염 이후에 Condylomata acuminata 발생 위험이 높은 것 같습니다.

The risk for development of CA after incident HPV-6 or HPV-11 infection appears to be high. In a cohort study of 473 18- to 21-year-old sexually active men who underwent triannual genital examinations, the cumulative incidence of genital wart development over 24 months was 58 percent (95% CI 38 to 79 percent) among the 46 men with incident HPV-6 or HPV-11 infection. The cohort study of 603 female university students also found a high rate of genital wart development; triannual gynecologic examinations detected a 36-month cumulative incidence for genital warts among women with incident HPV-6 or HPV-11 infection of 64 percent (95% CI 51 to 77 percent).

수직 감염이 가능합니다.

Vertical transmission of HPV from pregnant women with anogenital warts to the fetus is possible.
