Before revision:  Strikingly, rescaling the fitted models with the binding rates of the spike proteins of SARS and SARS-CoV-2 allow predicting the fatality rate of SARS across age and gender with high accuracy , in particular its higher severity for young patients . The epidemiology of the common-cold coronavirus NL63 is also consistent with the model and existing data on the affinity of its spike protein , thus linking the molecular and epidemiological levels.
