[HEALTH SCARES: A CHRONICLE UNNECESSARY ANXIETY].

INTRODUCTION: A health scare is an event characterized by fear of catastrophic consequences with little actual results. Regardless of these negligible results, the health, social and economic impacts of such events may be significant. Health scares are spread throughout four major groups: the media, relevant medical experts, policy makers and the public at large. In this review, we described two recent cases in Israel: the case of Eltroxin exchange that occurred in Israel as well as other countries, in addition to the polio virus spread in sewage, in the context of health scares. Furthermore, we summarized the interaction between these groups, focusing on their functioning in selected health scares from the previous two decades. There is increased need for creating a priori coordinating methods, in order to deal efficiently with such events in the future. In that way, the implications of health scares can be reduce to minimum.
