This study aims to identify the HR-HPV genotypes and factors associated with major cervical abnormalities among women living in the sickle cell endemic area of Kisangani, DRC.  \nMethods  \nThis hospital-based cross-sectional study consisted to a face-to-face and semistructured questionnaire for collecting data of the socio-demographic, clinical and sexual behaviors characteristics of participants. The sickle cell status was confirmed using liquid chromatography coupled with mass spectrometry. Cervical smears were collected using the ThinPrep® Pap-test solution (Hologic Inc, Marlborough, USA) . The HR-HPV molecular analysis was performed using the Cobas® 6800 system (Roche Molecular Systems, Somerville, USA) for real time polymerase chain reaction (RT-PCR) and the Oxford Nanopore platform (Oxford Nanopore Technologies, Oxford, England) for the viral genome sequencing.
