Abstract

Introduction. Recent studies in Mexico have shown that from 20-10,000 to 58-10,000 newborns with Toxoplasma infection could be undetected. The aim of this study was to determine the weighed prevalence of T. gondii infection and describe the epidemiological transition of infection in newborns. Methods. Research literature reporting Toxoplasma infection prevalence in Mexican newborns and children were searched in five international databases. Weighted prevalence was calculated by inverse variance-weighted method in asymptomatic and symptomatic study groups, and the epidemiological transition was estimated by a lineal regression analysis. Results. The weighed prevalence in 4833 asymptomatic newborns was 0.616%, CI95% 0.396%–0.835% , whereas, among 895 symptomatic newborns, the weighed prevalence was 3.02%, CI 95% 1.91%–4.1% . A downward trend of 0.25%-year represented an accumulated decrease of −13,75% in the prevalence in the symptomatic newborns throughout 55 years, whereas, in the asymptomatic children, the prevalence was similar over the course of the years. Conclusion. The high-weighted prevalence of congenital Toxoplasma infection in newborns justifies that Toxoplasma gondii testing be included in the screening programs for women during pregnancy and newborns in Mexico. A rapid diagnosis and treatment strategy could aid in limiting a potential damage to the newborns.
