Prevalence of co-infection with human papillomavirus and Chlamydia trachomatis and risk factors associated with cervical cancer in Congolese women
The human papillomavirus (HPV) is one of the most frequently diagnosed viruses in developing countries. Chlamydia trachomatis (CT) is an important cofactor in HPV-induced cervical cancer. Cervico-uterine smears were taken for cytology, and a total of 131 samples were analysed. HPV prevalence and CT were detected using specific primers (L1 gene and omp-1 gene). 23 (17.5 %) HPV-only samples were detected, CT-only positives were 10 (7.6 %). And HPV/CT co-infection was 13 (9.9 %). Identified risk factors associated with HPV/CT co-infection were risky sexual behaviour and cytology status. The prevalence of HPV and CT and their co-infection rates being high in our study population, may be an indicator of cervical cancer risk. Consequently, there is an urgent need to raise awareness and take appropriate precautions.
