A Machine Learning Model for Evaluating Imported Disease Screening Strategies in Immigrant Populations

Abstract

Given the high prevalence of imported diseases in immigrant populations, it has postulated the need to establish screening programs that allow their early diagnosis and treatment. We present a mathematical model based on machine learning methodologies to contribute to the design of screening programs in this population. We conducted a retrospective cross-sectional screening program of imported diseases in all immigrant patients who attended the Tropical Medicine Unit between January 2009 and December 2016. We designed a mathematical model based on machine learning methodologies to establish the set of most discriminatory prognostic variables to predict the onset of the: HIV infection, malaria, chronic hepatitis B and C, schistosomiasis, and Chagas in immigrant population. We analyzed 759 patients. HIV was predicted with an accuracy of 84.9% and the number of screenings to detect the first HIV-infected person was 26, as in the case of Chagas disease (with a predictive accuracy of 92.9%). For the other diseases the averages were 12 screenings to detect the first case of chronic hepatitis B (85.4%), or schistosomiasis (86.9%), 23 for hepatitis C (85.6%) or malaria (93.3%), and eight for syphilis (79.4%) and strongyloidiasis (88.4%). The use of machine learning methodologies allowed the prediction of the expected disease burden and made it possible to pinpoint with greater precision those immigrants who are likely to benefit from screening programs, thus contributing effectively to their development and design.

Comparative Analysis of Hepatitis C Using K-Nearest Neighbor Classifier and Decision Tree Classifier

“…The Hepatitis C virus (HCV) is seen as a threat to society's health. (Fernández-Martínez et al 2021) This research aids in the early detection of Novel Hepatitis C Detection by using current methods such as machine learning technologies (Nilashi et al 2019;Rupani et al 2020). The major goal of this research is to use matlab programming software to assess the existence of Novel Hepatitis C Detection.…”
