Abstract
Objective: The aim of this study was to identify the molecular prevalence of high-risk HPV infection and the distribution of genotypes present in normal cytology, as well as to determine the vaccination status of our study population.
Methods: 110 cervical samples were taken from individuals, and 1 ml of each sample was added to the Xpert HPV cartridge in the sample compartment before it was placed in the Cepheid GeneXpert system. Detection was performed simultaneously via amplification of the E6 and E7 genes in five fluorescent channels (HPV16, HPV18/45, HPV31/33/35/52/58, HPV51/59, and HPV39/56/66/68a).
Results: 36/110 (33%) of all samples tested were positive for HPV DNA. The predominant genotypes were HPV16 (12.7%) and other pooled HR-HPV types (8.2%). All women who received the Gardasil-9 vaccine (3.6%) had HPV, and infection was associated with travel outside Africa. 96.4% of the screened individuals had not received any HPV vaccine.
Conclusion: Our research confirms a widespread HR-HPV infection in our population and extends the importance of studies on the molecular prevalence of HPV, particularly in women with normal cytology and apparent good health, in view of the cruel lack of public awareness of HPV infections.
