Oregonâs statewide syndromic surveillance system (Oregon ESSENCE) has been operational since 2012. Non-federal emergency department data (and several of their associated urgent care centers) are the primary source for the system, although other data sources have been added, including de-identified call data from OPC in 2016. OPHD epidemiologists have experience monitoring mass gatherings and have a strong relationship with OPC, collaborating on a regular basis for routine and heightened public health surveillance.

Syndromic surveillance is the near real-time monitoring of key health indicators in emergency department (ED) and urgent care visits. Oregon ESSENCE tracks the number of visits for specific patient symptoms using chief complaints (what the patient says is the reason for their visit) and discharge diagnosis codes. Visit information is collected from EDs and urgent care centers across the state. Currently, all 60 eligible hospitals are sending ED data every day for syndromic surveillance. Some urgent care centers are currently reporting. See
Champaign County is one of the largest counties in central Illinois with a population of ~207,000 and is home to the University of Illinois at Urbana-Champaign which currently has 44,500 students. In the fall the university hosts Big Ten football games which have recently been drawing an average attendance of ~45,000 people, many traveling from Chicago or other parts of the Midwest. The twin cities host a number of community events and festivals throughout the Spring and Summer. Typically the community festivals have liquor licenses whereas no alcohol is served in the football stadium.
Super Bowl XLIX took place on February 1st, 2015 in Glendale, Arizona. In preparation for this large scale public event and related activities, the Maricopa County Department of Public Health (MCDPH) developed methods for enhanced surveillance, situational awareness and early detection of public health emergencies.
LAC hosted the 2015 Special Olympics (SO) which welcomed approximately 6,500 athletes from 165 countries, as well as 30,000 volunteers and 500,000 spectators from July 25 to August 2, 2015. International athletes were not required to show proof of vaccinations and were housed in dormitories for nine days, creating potential for infectious disease outbreaks.
We assessed the impact of the London 2012 Olympic and Paralympic Games on syndromic surveillance systems including the incidence of syndromic indictors and total contacts with health care.
Mass gathering is defined by WHO as – “More than specified number of persons (which can be as few as 1000 persons to more than 25000) at a specific location for a specific purpose (social function, large public event or sports competition) for a defined period of time” . Mass gatherings are considered to have the potential for public health incidents, outbreaks and casualties attributed to the inevitable overcrowding in a place.
The 'Grand Raid de la Reunion' is one of the hardest ultra trails in the world (5,350 competitors in 2012). This one stage race takes place in Reunion Island, a French overseas department in the Indian Ocean. Ultra trails and ultra marathons are intense long-distance running races pushing back human physical abilities' limits. In general terms, studies about these races highlight different severity levels' injuries, from asymptomatic to critical condition [1-4]. No study has yet used syndromic surveillance to study the impact of such sporting events on ED visits.
