Abstract

This article investigates congenital syndrome associated with the Zika virus (ZIKV) in newborns in Brazil, utilizing preprocessing techniques and machine learning to enhance its detection. The study proposes the Ant Colony Optimization (ACO) algorithm for instance selection in a database on ZIKV infections from 2016, during a period when Brazil faced a Zika outbreak linked to neurological complications such as microcephaly. The research compares the performance of ACO with five classification algorithms, demonstrating that ACO improved all evaluation metrics. The highest case concentration was observed in Brazil’s Northeast and Southeast regions. Although cases have decreased in 2024, it is essential to maintain monitoring and preventive actions. In summary, the results confirm the effectiveness of ACO in enhancing machine learning models and highlight the importance of clinical attributes in the early detection of congenital syndromes, recommending the use of updated databases for a better understanding of the impact of ZIKV, particularly in newborns.
