The authors reviewed data from 1,099 laboratory-confirmed COVID-19 patients in 552 mainland China hospitals through January 29, 2020. The cumulative risk of the composite end point of admission to an intensive care unit, use of mechanical ventilation, or death was 3.6% for all patients and 20.6% for patients with severe disease. The authors noted that 15.7% developed severe illness after hospital admission; 1.4% died; 43.8% of patients presented with fever, but 88.7% developed a fever while hospitalized; and 2.9% of those with severe and 17.9% of those with non-severe disease had no radiologic abnormalities on initial presentation.
