Epidemiology of Human Papillomavirus in the Middle East and North Africa: A Review of Genotypic Prevalence, Vaccination Challenges, and Non-Cervical Clinical Outcomes

Background: Human papillomavirus (HPV) is the most common sexually transmitted infection and the primary etiological agent of cervical cancer. Despite the high global disease burden, the Middle East and North Africa (MENA) region faces substantial challenges in HPV prevention and control. This narrative review aimed to synthesize existing evidence on the prevalence, genotypic distribution, awareness, vaccination status, clinical outcomes, and the role of HPV in non-cervical malignancies in the MENA region. Methods: PubMed, Web of Science, Scopus, and Google Scholar were searched, and 122 studies were included. Findings were synthesized qualitatively and descriptively. Cohort studies, systematic reviews, and meta-analyses were prioritized to support inferences about associations and potential causal relationships. Results: HPV prevalence in the general female population of the MENA region ranged from 4.7% to 53.3%, exceeding 90% in high-risk groups and patients with malignancies. The most common genotypes were HPV16 and HPV18; however, distribution patterns varied across populations. Key risk factors included younger age, multiple sexual partners, early age at first sexual intercourse, smoking, and alcohol consumption. General awareness was low to moderate, and vaccination coverage was very low in most countries. Barriers included lack of knowledge, fear of side effects, religious concerns, and social stigma. Evidence also indicates an association between HPV and non-cervical malignancies (head and neck, esophageal, gastric, breast, and thyroid cancers), with HPV DNA detected in tumor tissues. Conclusions: HPV poses a significant public health challenge in the MENA region, characterized by high prevalence, genotypic diversity, limited knowledge and awareness, and unsatisfactory vaccination coverage. Expanding screening and vaccination through financial support, culturally and religiously appropriate education, and longitudinal studies to monitor genotypic changes and associations with other malignancies are essential measures to reduce the burden of HPV-related diseases in the region.
