Human papillomavirus in Thai women and men with anogenital warts: A retrospective study
Anogenital warts are caused by human papillomavirus (HPV). HPV genotype 6 and 11 are most often associated with anogenital warts. The diversity of HPV genotypes found in Thai patients with genital warts is not well-characterized. The objective of this study was to investigate HPV-associated anogenital warts in the Thai population and whether genotypes found are represented in the vaccine. A total of 206 anogenital swab samples were analyzed for HPV DNA by PCR and sequencing. HPV positive was identified in 88.3% (182/206) of the samples. The majority of HPV (75.2%) were low-risk genotypes HPV6 and HPV11. Thus, HPV6 and HPV11 were most common infection in genital wart. We conclude that the quadrivalent vaccine could potentially prevent 84.5% of the genital warts found in the Thai population.
