I am thinking SARS could be a very serious health peoblem for a very large number of people. If say a billion people get SARS over the next couple years then at a 5% mortality rate we are talking in the neighborhood of 50,000,000 deaths. If we are talking a 16% mortality rate then we are talking about 160,000,000 dead over a two year period. I do not know if it will develop into that big a pandemic but it is a concern. However given the disease I do not see a whole lot that can be done to avoid this happening.
