Some viruses and bacteria can survive on surfaces for 24 hours and others live for weeks
These surviving germs can quickly spread throughout a building. In a study conducted by Dr. Charles Gerba, a microbiologist at the University of Arizona,
a “racer” virus was planted on a single doorknob. It quickly spread throughout an office and ended up on 50% of the occupants’ hands
and office surfaces.
No matter how thorough a cleaning crew may be, when faced with this type of rapid dissemination,
people need to take defensive measures into their own hands.
And facility maintenance needs to provide the proper supplies to enable occupants to do so.
Studies show a large majority of us do not properly wash our hands, however
posting signage has been shown to be effective in increasing hand washing compliance.
