Toxoplasmosis is an infection caused by the parasite Toxoplasma gondii, which involves complex interactions with the host's immune system. The pathogenic process includes innate and adaptive immune responses, with a highlight on phagocytic cells and T cells in defense against the parasite. Commonly, with aging, there are implications on the individual's immune mechanisms. Based on these premises, the aim is to discuss the interfaces of toxoplasmosis with aging, aiming to identify relevant factors for the outcomes of this health-disease process. For this purpose, a narrative review of the scientific literature available in databases such as Scielo, Google Scholar, and PubMed was carried out. It was possible to identify that toxoplasmosis prevention involves measures such as food hygiene, avoiding contact with cats, and serological screening during pregnancy. Treatment varies according to the severity of the infection and the patient's immune status, involving specific therapy against the parasite and supportive treatment for complications. Understanding the pathogenesis, implementing preventive measures, and ensuring adequate therapeutic management are essential to reduce the incidence and impact of toxoplasmosis on public health, especially in at-risk groups such as pregnant women, elderly individuals, and immunocompromised individuals
