| Abstract: | Human papillomavirus infection of the genital tract was identified by the filter in situ hybridization test. Exfoliated cervical cells were tested separately for the prevalence of human papillomavirus 6/11 and 16/18. Human papillomavirus deoxyribonucleic acid (DNA) was identified in 70 and 92% of specimens of U.S. and West German women, respectively, who showed concurrent cytologic and colposcopic abnormalities, and in 50 and 54% of women, respectively, who showed neither cytologic nor colposcopic abnormalities at the time of examination. In the cytologic categories of condyloma, mild to moderate dysplasia (cervical intraepithelial neoplasia I/II), and severe dysplasia-carcinoma in situ (cervical intraepithelial neoplasia III), the overall DNA detection rate of human papillomavirus 6/11 and 16/18 varied between 75 and 83%; but human papillomavirus 16/18 was recovered relatively more frequently from the more severe lesions. Forty-eight West German women were monitored cytologically over a period of three to 24 months; progression to carcinoma in situ (cervical intraepithelial neoplasia III) was correlated with initial isolation of human papillomavirus 16/18. The vagina and vestibule were found to be frequent sites of human papillomavirus infection with the same virus type as in the cervix. In an investigation of male partners of 40 human papillomavirus-positive women, human papillomavirus was identified in exfoliated cells from 26; in 19 instances, the males harbored the same human papillomavirus types as their female partners. |
