Here is a little anecdote about the hand disinfection gel.
Couples years ago, during another paranoia epedemic, my wife and I had a conversation with a friend of her about those hand disinfection gel that were mandatory at entrance of hospital and sometimes with a security guard to ensure compliance. Both my wife and her friend worked at the local hospital. We were saying to this person that hand disinfection gel is not helpfull at controlling disease and probably a bad thing since the gelling agent left on your hand after the alcohol evaporate will probably constitute a nice culturing medium.
No need to say that the person doubted what we were saying, in fact probably thinking we were completely crazy to question the acts of highly competent authorities. However it picked enough her curiosity that once at work she asked the doctor acting as the chief of the microbiology department (I won't name the guy) if the use of those disinfection gel at the entrance of the hospital was really effective. The answer of the doctor was that is was ONLY to reassure the public and had no benefit for infection control.
