“…Thus, for this example, the following association rules are developed: S5→(S2,S1); (S1,S5)→S2 and (S2,S5)→S1. It has been noticed that the apriori algorithm of association rule mining has already been successfully deployed for prediction/diagnosis of heart diseases (Said et al, 2015;Domadiya & Rao, 2018;Jamsheela, 2021), dengue (Jahangir et al, 2018), brain tumor (Sengupta et al, 2013), chronic kidney disease (Alaiad et al, 2020), infectious diseases (Brossette et al, 1998), pandemic diseases (Burvin & Dhanalakshmi, 2018;Aiswarya et al, 2020), COVID-19 (Çelik, 2020;Shawkat et al, 2021;Tandan et al, 2021), pediatric primary care (Downs & Wallace, 2000), treatment of patients in an emergency department (Sarıyer & Taşar, 2020) etc. In this paper, based on a huge dataset of COVID-19 patients and using the FP growth algorithm of association rule mining, an attempt is put forward to discover COVID-19 symptom patterns and rules which would support the initial identification of severe COVID-19 cases for early treatment and isolation.…”
