Clinical features, including age and comorbidities (e.g., lung disorders, cardiovascular diseases, and diabetes mellitus) and easily available laboratory parameters (e.g., C-reactive protein (CRP), lactate dehydrogenase (LDH), lymphocyte count, and absolute eosinopenia), have been established as consistent predictors of severe COVID-19 (e.g., pneumonia or immediate care unit admission) and a fatal outcome [2,3,4,5]. Here, CRP is linked to susceptibility to pneumonia measurement.
