Also, it would be good if the scientists/medical experts decided the highest risk groups - is it men/women, is it young/old, is it pre-existing conditions and if so, which ones.
Sorry but is this not already pretty widely known?
Men are higher risk than women
Old are higher risk than young
Pre-existing medical conditions include Diabetes, Lung Disease, Cancer, Immunodeficiency, Heart Disease, Hypertension, Asthma, Kidney Disease and Liver Disease.
The New York Stats from 14th of April give a pretty accurate picture:

Female deaths: 38.2%

45-64 : 23.1% / 3.5%
65-74: 24.6% / 6%
75+ : 47.7% / 14.2%
