Mitigation and Prevention
This article discusses the challenges of contact tracing among people experiencing homelessness. It suggests combining the traditional person-based approaches to contact tracing with location-based contact tracing approaches when conducting investigations among unhoused individuals. Location-based approaches collect data on the places people have visited in the past 48 hours, rather than the individuals with whom they interacted. Facility-wide testing and resources can be provided in locations where someone accessed support services.
