Typically, mass gatherings are considered to be events that have at least 1000 people; however, this does not have to be the case.1,2 In fact, large organizations including the World Health Organization and the U.S. Federal Emergency Management Administration do not focus on the number of attendees when defining mass gatherings; rather, they recognize the impact on the surrounding resources.
