spontaneously, such as a president's memorial service, mass gatherings present several problems. They are associated with crowding

temporary food and sanitation facilities, and challenging security situations. The risk of infectious diseases increases

of

people--sometimes numbering

in the millions-at a specific location, for a specific purpose, and for a defined time frame.
