Abstract: Infection control methods and systems associate proximity-detection devices with people in a population, such as people in a hospital. Each proximity-detection device detects proximity events with other people. The methods and systems detect proximity events and, for person-to-person pairs who were involved in such an event, records at least one risk value as a measure of risk of an infectious agent having been transferred between the pair. Upon indication of an infectious agent transfer to a member of the population, a health worker may conduct an infection control intervention on members of a subpopulation of people based on detected proximity events and risk values. The method and system may be extended to fomites. Correlations may be made over multiple infection events.
