ABSTRACT
INTRODUCTION:
Chronic chagas disease remains a relevant public health challenge in brazil1. Despite advances in vector control, late diagnosis and long-term morbidity continue to affect adult and older populations2. This study aimed to describe the epidemiological profile of chronic chagas disease cases reported in the state of ceará between 2023 and 2024.
METHODS:
This is a descriptive epidemiological study conducted using secondary data from the national surveillance system e-sus notifica. All cases of chronic chagas disease reported in ceará between january 2023 and december 2024 were included. The variables analyzed were sex, age group, race or color, educational level, area of residence, and municipality. Data analysis was performed using descriptive statistics. The study was approved by a research ethics committee.
RESULTS:
A total of 263 cases were analyzed. There was a predominance of males with 175 cases, corresponding to 66.53 percent, while females accounted for 88 cases, equivalent to 33.47 percent. The most frequent educational level was incomplete elementary education with 63 cases, followed by individuals with no formal schooling with 19 records. Regarding race or color, the brown category predominated with 154 cases. Notifications were concentrated in 2023 with 136 cases and in 2024 with 127 cases. Urban areas accounted for 119 records and rural areas for 67, while information was missing in 77 cases. The municipality with the highest number of notifications was juazeiro do norte, followed by limoeiro do norte and fortaleza.
CONCLUSIONS:
The findings highlight chronic chagas disease as a current and neglected condition in ceará, associated with late diagnosis, weaknesses in epidemiological surveillance, and a strong relationship with social determinants of health and social vulnerability.
