In 2003 a doctor with SARS unknowingly infected several guests while staying at a Hong Kong hotel, and overnight the virus reached across the globe. China is currently battling a bird flu that kills nearly half of the people infected.

An uncontrolled outbreak or bioterror attack could result in a contagion that kills over 30 million people.
