A survey says that some of those folks may not be willing to serve on the front lines should a pandemic occur. It's hard to blame anyone for willingly putting themselves at great risk every day. Bu, there are professions all over the place where that happens every day: bio-hazard workers, soldiers and ER surgeons I think qualify here -- among many others.
Moral of the story here? The education of those that would be at the front lines of a pandemic is not where it should be. The precautions and tools are there -- it just takes a very skilled professional to know and use them.
