The study aimed to determine the seroprevalence and determinants of HIV and co\u2010infection with hepatitis B virus (HBV), hepatitis C virus (HCV), and syphilis among pregnant women attending antenatal care in Luanda, the capital city of Angola. A cross\u2010sectional study was conducted with 1612 pregnant women screened for HIV during antenatal care. HIV\u2010reactive were also screened for the HBV, HCV, and syphilis using immunoassay kits. A logistic regression model, adjusted odds ratios (AOR) and their 95% confidence interval (CI) were calculated with a level of significance set at 5%. The overall seroprevalence of HIV was 2.6%. About 13% of HIV\u2010positive pregnant women were coinfected. From which, 7.5% were reactive to HBV and 5% to syphilis. There was no reactivity to HCV. Pregnant women younger aged than 25 years were significantly protected from HIV\u2010infection (AOR, 0.43 [95% CI, 0.20\u20100.91], <jats:italic>P<\/jats:italic>\u2009=\u2009.026). The co\u2010infection was 1.3 times (AOR, 0.04\u201041.0) in younger aged than 25 years, 7.0 times (AOR, 0.50\u201099.2) to residents in urbanized areas, and 1.4 times (AOR, 0.10\u201020.9) in pregnant women with a high educational level. In conclusion, infectious diseases are a public health burden among pregnant women in Luanda. However, include an integrated antenatal screening mainly in urbanized areas is crucial to reduce the spread of infectious diseases in different communities of Angola.<\/jats:p>","DOI":"10.1002\/jmv.26148","type":"journal-article","created":{"date-parts":[[2020,6,9]],"date-time":"2020-06-09T12:00:58Z","timestamp":1591704058000},"page":"3265-3270","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["HIV, hepatitis B virus, hepatitis C virus, and syphilis among pregnant women attending antenatal care in Luanda, Angola: Seroprevalence and risk factors"],"prefix":"10.1002","volume":"92","author":[{"given":"Cruz S.","family":"Sebasti\u00e3o","sequence":"first","affiliation":[{"name":"Molecular Biology Laboratory Instituto Nacional de Investiga\u00e7\u00e3o em Sa\u00fade Luanda Angola"},{"name":"Department of Laboratory Centro de Investiga\u00e7\u00e3o em Sa\u00fade de Angola Luanda Angola"},{"name":"Instituto Superior de Ci\u00eancias da Sa\u00fade Universidade Agostinho Neto Luanda Angola"},{"name":"Laboratory of Immunobiology and Pathogenesis of CEDOC, NOVA Medical School, Faculdade de Ci\u00eancias M\u00e9dicas Universidade NOVA de Lisboa Lisboa Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zoraima","family":"Neto","sequence":"additional","affiliation":[{"name":"Molecular Biology Laboratory Instituto Nacional de Investiga\u00e7\u00e3o em Sa\u00fade Luanda Angola"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Domingos","family":"Jandondo","sequence":"additional","affiliation":[{"name":"Molecular Biology Laboratory Instituto Nacional de Investiga\u00e7\u00e3o em Sa\u00fade Luanda Angola"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marinela","family":"Mirandela","sequence":"additional","affiliation":[{"name":"Molecular Biology Laboratory Instituto Nacional de Investiga\u00e7\u00e3o em Sa\u00fade Luanda Angola"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joana","family":"Morais","sequence":"additional","affiliation":[{"name":"Molecular Biology Laboratory Instituto Nacional de Investiga\u00e7\u00e3o em Sa\u00fade Luanda Angola"},{"name":"Department of Laboratory Centro de Investiga\u00e7\u00e3o em Sa\u00fade de Angola Luanda Angola"},{"name":"Faculdade de Medicina Universidade Agostinho Neto Luanda Angola"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6394-658X","authenticated-orcid":false,"given":"Miguel","family":"Brito","sequence":"additional","affiliation":[{"name":"Department of Laboratory Centro de Investiga\u00e7\u00e3o em Sa\u00fade de Angola Luanda Angola"},{"name":"Health and Technology Research Center, Escola Superior de Tecnologia da Sa\u00fade de Lisboa Instituto Polit\u00e9cnico de Lisboa Lisboa Portugal"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,6,24]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/olq.0b013e31818d3cad"},{"key":"e_1_2_8_3_1","unstructured":"Unaids.
