Objectives to identify the prevalence of toxoplasmosis during pregnancy according to race or ethnicity through a systematic review. Methods the protocol was registered in PROSPERO (CRD42024596261). Searches were conducted in PubMed, LILACS, Web of Science, Scopus, CINAHL, and Google Scholar using descriptors related to toxoplasmosis, pregnancy, prenatal care, and race/ethnicity combined with Boolean operators. Cross-sectional studies reporting prevalence among pregnant women according to racial or ethnic groups were included. Results of the 4, 652 records identified, 10 studies met the inclusion criteria. Data were extracted, organized, and analyzed qualitatively. The findings revealed differences in toxoplasmosis prevalence between ethno-racial groups. In Brazil, higher prevalence was observed among Pardo (mixed-race) and Indigenous populations. In the United Kingdom, Afro-Caribbean women showed a prevalence of 31. 48%. In Sri Lanka, Sinhalese women had higher prevalence (13. 56%) compared to non-Sinhalese women (6. 3%). Variations across continents were evident. Conclusion significant disparities in toxoplasmosis prevalence during pregnancy were identified among ethno-racial groups, especially among Pardo, Indigenous, and Black populations, highlighting the need for broader multicenter investigations worldwide.
