contact tracing

Infection chain mapping

Contact tracing is the public health practice of identifying people who have been in close proximity to someone with an infectious disease.

Health workers interview infected individuals, then reach out to their contacts to recommend testing, monitoring, or quarantine.

The method became widely familiar during the COVID-19 pandemic: Contact tracers worked around the clock as cases surged.
