Human T-lymphotropic virus (HTLV) antenatal screening is not mandatory in Spain. Surveys conducted decades ago reported HTLV-1 seroprevalence rates of 0.2% among foreign pregnant women in Spain. The migrant flow to Spain from HTLV-1 endemic regions in Latin America and sub-Saharan Africa has increased during the last decade. Currently, 25% of pregnant women in Spain are foreigners. Methods. From January 2021 to October 2023 a cross-sectional study was carried out in all consecutive pregnant women attended at eleven Spanish clinics. A commercial enzyme immunoassay (EIA) was used for screening of serum HTLV-1/2 antibodies. Reactive samples were confirmed by immunoblot. Results. A total of 9813 pregnant women with a median age of 34 years-old were examined. Native Spaniards were 6977 (76.5%). Of 2147 foreigners (23.5%), 903566 (9.9%) were Latin Americans, 416 (4.5%) North Africans, 293 (3.2%) from Romania, and 196 (2.1%) from sub-Saharan Africa. A total of 47 samples were EIA reactive but only five were confirmed as HTLV-1 positive using immunoblot. Infected women came from Paraguay, Colombia, the Dominican Republic, Venezuela and Peru. All but one were primigravida, with ages ranging from 20 to 33 years-old. One was HIV-1 positive, and another was infected with Chlamydia trachomatis. Conclusion. The overall seroprevalence for HTLV-1 among pregnant women in Spain is 0.05% but rises ten-fold (0.55%) among Latin Americans. This rate is higher than in surveys conducted decades ago. Our results support that anti-HTLV testing should be part of antenatal screening in Spain in pregnant women coming from Latin America, as it is already done with Chagas disease. info:eu-repo/grantAgreement/ES/ISCIII/FIS/PI21-1717 info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 1.7 2024 0.575 2024 Public Health, Environmental and Occupational Health 2024 Q2 Epidemiology 2024 Q3 Infectious Diseases 2024 Q3 2.5 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Benito, Rafael Universidad de Zaragoza (orcid)0000-0001-5134-1006 Rojo, Silvia Reina, Gabriel Montiel, Natalia Aguilera, Antonio Eiros, José María García-Costa, Juan Ortega, Diego Universidad de Zaragoza Arco, Irene Hernánez-Batancor, Araceli Soriano, Vicente de-Mendoza, Carmen Calderón, E.
