However, to define a mass gathering simply by the number of participants is inadequate.1 A more conceptual definition has been suggested by Arbon, which endorses the idea that a mass gathering is a collection of people that because of its inherent features including density of people, location, or environment may limit medical access.1 Mass gatherings occur in nearly every conceivable location and condition and hence pose unique challenges to the medical provider for planning purposes and provision of medical care.
