See how age and illnesses change the risk of dying from covid-19

Covid-19 threatens everyone, but its risk is concentrated among particular groups of people. To help readers understand how the disease interacts with demography and with other illnesses (“comorbidities”), we have built a statistical risk model, using records in the Covid-19 Research Database from 425,000 people in America who tested positive. For any group of unvaccinated people of a given age, sex and mix of comorbidities, our model estimates the share that would be hospitalised or die within 30 days of a covid-19 diagnosis. To learn more about which medical conditions most exacerbate covid-19, please see Graphic Detail; the model’s methodology is summarised here.
