Gofer,
I don't have the time or the data to do the whole world, but at my website
http://home.so-net.com.hk/~pns/ I am maintaining a summary of the latest official figures for Hong Kong and compare them to risks associated with some other conditions (again based on WHO and other official sources).
If I have time this weekend I will add a graph (or at least a table)showing the trends over time for SARS in HK.
