Abstract: A contact tracing system and method identifies which persons at a facility may have been exposed to a possibly contagious person. In some examples, multiple sensors, such as access card readers and cameras with video and thermographic imaging, monitor individuals at the facility. For each person, the system collects data pertaining to an individual's location and/or temperature at discrete points in time. In addition to collecting data throughout the day, data is also collected over an extended period of days or weeks. Based on data recorded during the extended periods, the system determines each person's typical schedule and travel pattern through the facility. When one or more sensors detect a possibly contagious person by sensing a fever, or even a gradually rising body temperature, the system searches for person's whose typical schedule and travel patterns overlap with those of the contagious person. The system then automatically notifies people accordingly.
