A phobia indicates an irrational and persistent fear and revulsion of certain situations, objects, activities, animals or people, which can sometimes be limiting and can have an impact on our everyday life.
Almost everyone has a more or less pronounced phobia, but while some are very rare and particular, others are widespread.
The 'World Mental Health Survey Initiative', a collaborative project of the WHO, Harvard University and the University of Michigan, has ranked the most widespread phobias.
