Persistent infection with high-risk human papillomavirus (HR-HPV) is the leading cause of cervical precancerous lesions and cervical cancer. The aim of the study was to evaluate the prevalence of high-risk HPV (HR-HPV) types among women with cervical intraepithelial neoplasia (CIN 2-3) and to evaluate the interest of high-risk HPV typing by hybrid capture 2 (HC2) in severe cervical dysplasias. 110 women were subjected to cyto-histological diagnostics and to the HPV test by HC2. The HC2 performance tests included Chi 2. Our results showed that the average age at the gynecological consultation in relation to cervical lesions was 38.75 ± 9.59 (22-72 years). The overall prevalence of HPV infection was 41.8%. High-risk HPV (HR-HPV) was detected in 31.8% of the total patients. In comparison with the other cytopathological stages, the HC2 test made it possible to evaluate the rate of HR-HPV at the CIN2/3 stage at 86% (p<0.0061). In conclusion the prevalence of HR-HPV associated with cervical lesions is comparable to those in the literature. HC2 Allows good detection of HR-HPV in severe cervical dysplasias and can be used to compensate for the absence of vaccines in our country.
