Uterine cervical neoplasms
We examined the prevalence of human papillomavirus (HPV) infection in Brazilian women with cervical intraepithelial neoplasia. Our goal was to identify the types of HPV and their association with risk factors. This prospective cross-sectional study included 97 samples collected from women aged 14-79 years at the public health units of gynecological care in São Luís, MA, Brazil. HPV detection was performed by nested polymerase chain reaction and sequence analysis.
