Human papillomavirus (HPV) is a significant etiological factor for several types of cancer, including cervical carcinoma, with 80% of cases of cervical cancer occurring in Latin America. In Brazil, cervical carcinoma is the third most prevalent cancer among women, and the northern region and the state of Amazonas have the highest incidence in the country. However, not all women benefit from cervical cancer screening measures. Most women in the LGBTQIA+ community do not seek gynecological health services since they often face barriers related to female homosexuality when accesing sexual health services. Using PCR, this study perfomed the molecular detection and genotyping of HPV in thirty-six patients (20 homosexual and 16 bisexual women) from Manaus, Amazonas, Brazil. Samples of the cervical epithelium were taken during the preventive examination and genotyping was perfomed to detect HPV 16, 18, 31 and 58. Of the thirty-six patients analyzed in this study, 88% of bisexual women (n=14) and 60% of homosexual women (n=12) tested positive for HPV. The HPV 18 genotype was the most frequent among the findings. The results indicate that homosexual and bisexual women are more vulnerable to HPV infections due to the lack of more specific gynecological care directed to this group, which includes the lack of training of professionals to deal with the particularities of this population group. Therefore, more HPV screening studies for LGBTQIA+ women and improved training for specialized health professionals are needed.
