Human papillomavirus viral load in cervical intraepithelial neoplasia as a prognostic factor in a Mexican population.

Persistent infection with human papillomavirus (HPV) has been recognized as the main etiological factor of morbimortality in cervical cancer. Several factors have been associated with the development of cervical disease, but viral load has recently been proposed as an indicator of cervical neoplasia. Therefore, a single measurement of viral load could be a suitable biomarker.
