Guangdong officials point to news reports that said 24 people had died and 680 had been infected in that city by the end of February. SARS is poorly understood and scientists have yet to nail down its cause.

24 / 680 = 3.5%

6,000,000,000 worldwide population * 3.5% = 210,000,000 deaths worldwide assuming the mortality rate is correct and remains constant.

Ok well I forgot to mention that not everyone would be succeptable and aquire the disease. However many of the infected individuals have not recovered and may yet die. So the mortality rate may be higher.
