With at least one cardiovascular related disease (hypertension, diabetes, stroke, heart disease) 0 2
High Fever (temperature ≥ 38.5 ℃) 0 2

  1. The risk of a COVID-19 patient for becoming a severe patient can be measured by this screening tool, and its risk score equaled to the total score of above seven predictors
  2. aAccording to the OR values of above predictors, they were categorized into different level risk factor: not discernible, weak, middle, strong and very strong level risk factors, their risks were weighted as 0, 1, 2, 3 and 4 respectively
