EPIDEMIOLOGICAL PROFILE OF CONGENITAL TOXOPLASMOSIS IN PARANÁ: AN ANALYSIS FROM 2020 TO 2025

Abstract

Congenital toxoplasmosis is a major public health concern due to its potential ophthalmological, neurological, and systemic impacts. This descriptive, observational, and quantitative study analyzed the epidemiological profile of notified cases in Paraná between 2020 and 2025 using secondary data from SINAN. Variables included case counts, sex, geographic distribution, clinical evolution, and deaths. Results showed a growing trend in notifications, concentrated in regional healthcare hubs, with no significant differences between sexes. Notably, a high proportion of records were incomplete or blank, particularly regarding follow-up and clinical evolution. In conclusion, congenital toxoplasmosis remains a critical issue in Paraná, highlighting the urgent need to strengthen epidemiological surveillance, improve information system data quality, and expand early diagnosis and follow-up strategies.
