WHAT’S KNOWN? (what is already known about this subject?)
The severity of the COVID-19 pandemic is associated with the survival of
individuals, and evaluating the level of severity, especially in
individuals with chronic diseases, improves the quality of life and can
reduce the mortality rates caused by this virus. The severity of the
COVID-19 disease was divided into four stages, i.e., mild, moderate,
extreme, and serious, in accordance with the Guidelines provided by the
Ministry of Health, Labor and Welfare, Japan, on the Diagnosis and
Treatment of Novel Coronavirus. There have been limited studies
investigating between the severity of COVID-19 infection and the various
demographic/clinical characteristics of individuals using an intelligent
ensemble model. Thence, this study investigates to design an intelligent
model that predicts the disease severity level by modeling the
relationships between the severity of COVID-19 infection and the various
demographic/clinical characteristics of individuals.
