College students are characterized by being young women of reproductive age who may have risky sexual behavior. To describe the prevalence and factors associated with endocervical infection by C. trachomatis and HPV in college women in the Brazilian Amazon. Endocervical secretions were collected. The ompA gene of C. trachomatis and the L1 gene of HPV were detected. The Chi-square test, Fisher\u2019s exact test, G test, Odds Ratio, and Multiple Logistic Regression were used with 95% confidence interval and p \u2264 0.05. The overall prevalence of endocervical infection by C. trachomatis was 8.3% (25\/302) and by HPV was 28.9% (87\/302). Low income was associated with sexually transmitted infection by C. trachomatis (14.8%, p = 0.0336). Those under 25 years old had twice the chance of HPV infection [39.3%, (OR: 2.6989), 95% CI: 1.6054\u20134.5371, p = 0.0002], as did women without children [31.8%, (OR: 2.333), CI: 1.1235\u20134.8461, p = 0.0307]. Women who did not study in a public school had 63% reduced risk of acquiring HPV infection [45.8% (OR: 0.3713), CI: 0.1951\u20130.7064, p = 0.0035]. C. trachomatis and HPV infections were present in low-income, childless young women who attended public schools, requiring the intensification of STI prevention policies in the Amazon region.<\/jats:p>","DOI":"10.3390\/microorganisms14061176","type":"journal-article","created":{"date-parts":[[2026,5,25]],"date-time":"2026-05-25T00:30:33Z","timestamp":1779669033000},"page":"1176","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["High Burden of Chlamydia trachomatis and Human Papillomavirus Infections in Low-Income Female University Students from Public Schools in the Brazilian Amazon"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0253-7277","authenticated-orcid":false,"given":"Leonardo Miranda dos","family":"Santos","sequence":"first","affiliation":[{"name":"Laboratory of Molecular and Cellular Biology, Center for Tropical Medicine, Federal University of Para, Belem 66075-110, PA, Brazil"},{"name":"State Department of Education of Par\u00e1, Government of the State of Par\u00e1, Belem 66020-080, PA, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8664-8171","authenticated-orcid":false,"given":"Rodrigo Covre","family":"Vieira","sequence":"additional","affiliation":[{"name":"Laboratory of Molecular and Cellular Biology, Center for Tropical Medicine, Federal University of Para, Belem 66075-110, PA, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Louise","family":"de Souza Canto Covre","sequence":"additional","affiliation":[{"name":"Laboratory of Molecular and Cellular Biology, Center for Tropical Medicine, Federal University of Para, Belem 66075-110, PA, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5434-4242","authenticated-orcid":false,"given":"Milena Cristina Martins","family":"da Silva","sequence":"additional","affiliation":[{"name":"Laboratory of Molecular and Cellular Biology, Center for Tropical Medicine, Federal University of Para, Belem 66075-110, PA, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9412-5573","authenticated-orcid":false,"given":"Thiago de Matos","family":"Bezerra","sequence":"additional","affiliation":[{"name":"Laboratory of Molecular and Cellular Biology, Center for Tropical Medicine, Federal University of Para, Belem 66075-110, PA, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Geraldo Mariano Moraes","family":"de Macedo","sequence":"additional","affiliation":[{"name":"Laboratory of Tropical Dermatology, Center for Tropical Medicine, Federal University of Para, Belem 66075-110, PA, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edna Aoba Yassui","family":"Ishikawa","sequence":"additional","affiliation":[{"name":"Laboratory of Molecular and Cellular Biology, Center for Tropical Medicine, Federal University of Para, Belem 66075-110, PA, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karla Val\u00e9ria Batista","family":"Lima","sequence":"additional","affiliation":[{"name":"Bacteriology and Mycology Section, Evandro Chagas Institute, Ananindeua 67030-000, PA, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9944-7838","authenticated-orcid":false,"given":"Ma\u00edsa Silva","family":"de Sousa","sequence":"additional","affiliation":[{"name":"Laboratory of Molecular and Cellular Biology, Center for Tropical Medicine, Federal University of Para, Belem 66075-110, PA, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rodrigo Vellasco Duarte","family":"Silvestre","sequence":"additional","affiliation":[{"name":"Papillomavirus and Retrovirus Laboratory, Virology Section, Evandro Chagas Institute, Ananindeua 67030-000, PA, Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,23]]},"reference":[{"key":"ref_1","unstructured":"World Health Organization (2025, March 20).
