Abstract
We evaluated the prevalence of human papillomavirus (HPV) infection in Amerindian women from a tribe in Brazilian Amazonia. Demographic data, pap smears and cervical samples for HPV DNA detection by polymerase chain reaction (PCR) were obtained for women aged above 10 years old. In total, 79 (85.9%) out of 92 eligible women who lived there were interviewed; all women already had engaged in sexual activity. Seventy-eight and 49 women allowed collection of pap smears and PCR samples, respectively. Cytological signs of HPV infection were observed in 11 patients; 6 of these were probed for HPV infection and 1 shown to be HPV 16. Overall prevalence of HPV infection detected by PCR was 14.3%. Three patients presented high-risk HPV DNA types:two HPV 16 and one co-infection of HPV 16 and 58. Cervical infection by oncogenic HPV types occurs in Amerindian women and cervical cancer screening should be a priority in this setting.
