Human papillomavirus type 31 infection of the uterine cervix in England.

A total of 452 uterine cervical scrapes, from two centres in England, has been examined by dot blot hybridisation for the presence of human papilloma virus (HPV) types 6, 11, 16, 18 and 31. HPV DNA was found in 36.5% samples. Twenty-nine of the women were infected with more than one type. Of those with detectable HPV, 14.5% had HPV type 31 infections. This type appears to cause significant infection of the genital tract in England.
