hi the icon is an abstract representation of the people there are five making a pentagram the pentagram is the symbol of Hygieia... the personification of the health in the greek mythology http://en.wikipedia.org/wiki/Hygieia
maybe too much symbolic, but also "nice" as icon in my opinion
just one question if you don't mind... what do you mean with "I placed this logo here by accident"... that is as "not interested" by accident (I guess that you can change anytime)
thanks again and good luck with the contest.... I hope you found the perfect logo
