Abstract

The first severe acute respiratory syndrome (SARS) outbreak occurred in China in 2002, followed by other coronavirus variants like MERS (2012), 2019-nCOV (2019), and Omicron (2020). While data mining (DM) has been widely used for SARS classification and decision-making, most studies overlook socioeconomic factors such as income and education. This study applies the cross-industry standard process for data mining (CRISP-DM) framework and DM techniques to predict severe SARS case progression in Recife, Brazil. Using open datasets, it incorporates attributes related to symptoms, pre-existing conditions, and socioeconomic indicators. Three healthcare experts participated in the analysis. Results showed that the apriori algorithm performed best in rule induction, while the decision tree slightly outperformed logistic regression. Notably, correlations emerged between severe case progression and socioeconomic data, underscoring the importance of integrating social determinants in disease classification models. These findings provide insights for improving predictive models and public health strategies.
