Toxoplasmosis, caused by the obligate intracellular protozoan parasite Toxoplasma gondii (T. gondii), is a globally prevalent zoonotic disease with potentially severe implications for immunocompromised individuals, pregnant women, and their fetuses/children. This study examined the prevalence of anti-T. gondii IgM and IgG antibodies in two groups of childbearing age women, including 653 participants in Group 1 (2013-2016) and 3221 participants in Group 2 (2019-2022). Our results revealed a decrease in the overall positivity rate of anti-T. gondii IgM antibodies from 2.32% to 1.06%, suggesting improved public health interventions over time. However, there were variations among different age groups and between rural and urban environments, with a significant decrease in urban areas across all age groups from Group 1 to Group 2. Regarding anti-T. gondii IgG antibodies, we did not observe a significant change in the seropositivity rate between the two groups. In the rural population with an age group over 35 years, we observed the highest positivity rate in Group 2. This study provided information on the risk factors and burden of toxoplasmosis in women of childbearing age with data that can be valuable to public health policies and the planning of healthcare measures for effective toxoplasmosis management.
