Graph of the SARS Epidemic: estimated 10 million deaths by October 2003
'The number of reported cases of SARS in the world is doubling every 17 days. This is implied by the slope of the blue curve, using the data available on April 19, 2003. There will be 100,000 cases on about July 7, 2003. A million cases will be reached on about September 2, 2003, and ten million on about October 28, 2003. These predictions will change every day as new data changes the slope of the curves. Only world cases after March 25, 2003 are used to compute the slope, because that is when China began reporting.

'The slope of red curve implies that the number of reported worldwide deaths due to SARS will double every 12 days. The number will be 100,000 on about August 8, 2003. A million deaths will be reached on about September 18, 2003, and ten million on about October 29, 2003. This forecast will change every day as new data changes the slope of the curves. Only world cases after March 25, 2003 are used to compute the slope, because that is when China began reporting.'
