Bacteria and Viruses to Humans -> I Am Invisible

Last week, in typical Controversies Blog fashion, we had a bit of a dust up discussing white coats and presenteeism. It occurred to me that in each instance, the primary barrier to infection prevention remains our inability to recognize that our adversaries are invisible. How else can we explain doctors insisting that washing white coats every three days is adequate and that they've never personally transmitted pathogens while caring for patients? So for those of us that still think hand hygiene compliance of 40% is satisfactory, contact precautions are bogus and that coming to work sick is cool, I have a three word reminder: pathogens are invisible. ciao
