DNA was successfully extracted from 91 cytobrush samples, amplifiedfor the detection of human papilloma viruses (HPVs) using GP5+/GP6+ primers, in addition totyping using type-specific primers for HPV-16 and HPV-18 genotypes.The overall HPV prevalence was 20.8% with the dominance of genotype 16 (36.6%) over thegenotype 18 (10.5%) and the presence of non-16, non-18 genotype(s) in 42.1% of all HPVpositive cases. Younger women aged 25 years or less were more infected (26.3%) with thedominance of genotype-16 (21.1%) and among women aged 36-45 years, the non-16/non-18genotype(s) were the more frequently observed (13.3%). Infection rates were more frequentamong women married above 30 years (33.3%) and those with more than one lifetime husband(28.6%). Women's husband with polygamy practice significantly covariate with HPV infections(P< 0.05).Significant association (P<0.001) was obvious between infection with any HPV and abnormalcytology. The non-16/non-18 genotype(s) were more involved (28%) whereas genotype-16 wasdetected more frequent (20%) than genotype-18 (4%). In addition mixed infection of both highrisk types (16 and 18) was limited only to women with abnormal Pap smears.In archival blocks, the presence of HPV- DNA was constant in pre-invasive sequamous cervicallesions as all blocks revealed a positive HPV-16 either alone or in combination with genotype-18.
