Planning for the management of health during the coronavirus requires more than solely a death toll. Measuring the costs of human suffering must also include mental illness, physical pain and a loss of quality of life that will follow this global crisis. This is where numbers play a role. Not to rate one life over another, but to limit the 'scarring effects' of this pandemic. David Johnston,  professor of health economics at Monash University.
