SARS is much more deadly than viral pneumonia, and much much more likely to put you in the hospital.
Some early mis-info on FR pointed out that hospital acquired pneumonia has a mortality rate of 9%, which was asserted to be higher than SARS. Hospital acquired pneumonia is more deadly than the pneumonia the public is generally afflicted with.
As an aside, the 4% mortality figure currently being used for SARS is computed by simply dividing the number of deaths by the number of victims. It is too soon to know how things will eventually work out, but the Hong Kong statistics are instructive. As of yesterday, Hong Kong had 970 cases. 800 were still in the hospital, some of whom will die. 142 had recovered, and 28 had died. I do not know the average length of a hospital stay, but based on the statistics it seems to be more than 2 weeks.
To say this is nothing more than a really bad cold is absurd.
