SARS Gets In Your Eyes
Research indicates the 2003 SARS outbreak at Amoy Gardens was spread by airborne transmission.
Flushing toilets created aerosols which were dispersed by winds and via dried U-traps in a faulty sewage system, where updrafts created by exhaust fans drew contaminated droplets into other bathrooms.
Surgicals masks wouldn't have prevented infection; the mouth and nose aren't exclusive entry points for airborne virii.
This is good argument for closing the toilet lid before flushing.
