Objective To elaborate a narrative review in order to evaluate the prevalence of toxoplasmosis in high-risk population groups with a global perspective to promote the development of strategies for the prevention and management of the infection among the referred groups. Introduction: Toxoplasmosis is an infection present in both humans and animals, considered a public health problem that is distributed globally. Among the population groups with a higher risk of developing alterations when acquiring this zoonosis are immunocompromised individuals, newborns born to mothers infected during pregnancy and women of childbearing age; the latter are considered to be at high risk due to the parasite's ability to cross the placental barrier. Many studies have been published regarding the seroprevalence of this infection, but there is insufficient information regarding the decrease or increase of the pathology in populations considered at risk. Methodology: A searched was carried out for articles in Spanish, English and Portuguese in the databases Google Scholar, ScienceDirect, PubMed, Scopus, Springer, ProQuest, Epistemonikos and Scielo, with a range of years between 2005 and 2020, using the keywords: newborn, immunosuppression, pregnant women, toxoplasmosis and prevalence. Results: The observed prevalence of toxoplasmosis in newborns ranged from 0.06% to 93% for IgG and IgM antibodies. The reported prevalence of IgG anti-Toxoplasma gondii antibodies in women of childbearing age ranged from 18% to 88.7%, and of IgM anti-Toxoplasma gondii antibodies ranged from 1.34% to 30.9% and finally in the group of people with Immunosuppression the prevalence of IgG anti-Toxoplasma gondii antibodies ranged from 8.8% to 94.3% for IgG and IgM antibodies. Conclusion: the routes of transmission of this infection are known and the population groups at risk are identified; however, it has not been possible to reduce the seroprevalence in the different countries, which indicates that it is necessary to create more adequate strategies to educate individuals and drastically reduce the presence of this zoonosis.
