What demographic factors are associated with severe
COVID-19?
Data on the characteristics of severe COVID-19 patients are uniformly
showing a correlation with age. According to the CDC National Vital
Statistic System on COVID-19 fatal outcomes, death rate doubles with
each decade after 45 years (National Vital Statistics System).
Comorbidities have also been associated with more severe
disease14. In Italy223 and
China224 hypertension (OR 2.36), chronic respiratory
disease (OR 2.46), cardiovascular disease (OR 3.42) and diabetes (OR
2.05) show a positive correlation with severity. Gender and ethnicity
have also been shown to impact COVID-19 severity (see questions
