In the CDC data, the likelihood of a Covid-19-related ICU admission was 2.2% to 2.4% in those without pre-existing medical conditions and 13.3% to 14.5% in those with such conditions. Despite these stark facts, health authorities have remained largely silent about underlying conditions. There has been no call to reduce coronavirus mortality by bringing diabetes or blood pressure under better control, or even to stop smoking. The "flatten the curve" strategy calls for handwashing, social distancing, and masks to slow the progression of the virus through the population. When these steps fail, as they often do, underlying conditions set the stage for rapid progression to a fatal outcome.
