According to this Washington Post story, SARS virus can:

• live as long as 24 hours on plastic surfaces under room temperature
• live as long as 4 days in diarrhea, 6 hours in normal feces, and 3 hours in baby feces.  Apparently acidity affects SARS virus.
• remain viable indefinitely at 32 degrees

Common detergents have no effect on SARS.  No words on disinfectants.  I used one of those pocket-size disinfectant jells while at Toronto.  I have no idea if it was effective, but it was reassuring.  I did run into a nurse at a party though.  When she mentioned that she was a nurse, everyone sort of paused.  Now the good news:

• SARS virus die at 98.6 degrees Fahrenheit and above.

Note that this doesn't mean you should bathe in boiling water, because doing that will just get you a hospital, a place you want to avoid when in a SARS zone.
