Frequency of rare and multi viral high-risk HPV types infection in cervical high grade squamous intraepithelial lesions in a non-native dominant middle eastern country: a polymerase chain reaction-based pilot study.

Infection by non HPV 16/18 is fairly common. A higher than expected incidence of rare subtype (20% hrHPV31) and multi-viral hrHPV (16%) were detected. This finding stresses the importance of this pilot study as currently only quadravalent vaccine is offered to control the HPV infection in the UAE population.
