Abstract

A growing body of literature is evidence that identifying subtypes of high-risk human papillomavirus (HR-HPV) has impacted on various steps of cervical cancer prevention.Thus, it is mandatory to determine the background prevalence and distribution of HPV subtypes for designing and implementing area-specific management. The present study was conducted to evaluate prevalence and distribution of HPV subtypes among women aged 30-70 years living in Lampang, an area with a high incidence of cervical cancer, through use of a mobile screening unit. Of 2,000 women recruited in this study, 108 (5.40%, 95%CI: 4.45-6.48) were found to have HR-HPV infection. Risk was significantly correlated with age and number of partners. Singly or in combination, the most common genotype was HPV 52 (17.6%), followed by HPV 16 (14.81%), HPV 58 (13.89%), HPV 33 (11.11%), HPV 51 (11.11%), and HPV 56 (9.26%). HPV 18 was found in only 5.6% of cases. Together, HPV 16/18 were noted in approximately 20.4% of cases. Eighteen(16.67%) women were positive with multiple subtypes of HR-HPV. Co-infection most frequently involved HPV 16 or HPV 58. These findings have obvious implications for vaccine policy.
