Contact Tracing, Intrastate and Interstate Quarantine, and Isolation

Contact tracing, quarantine and isolation are core communicable disease control measures used by public health departments as part of a comprehensive case ascertainment and management strategy. These are practices with historic roots enabled by state laws and policies, and have been used by other countries to slow and stop the spread of COVID-19. To date, their implementation as part of U.S. response efforts at the national, state, and local levels has been confounded by the scale of the COVID-19 outbreak; lack of a systemic infectious disease response; insufficient and fragmented funding streams; low levels of public accountability; and concerns about the impact of such efforts on individual privacy, liberty, and travel rights, as well as the financial and personal costs that may arise out of a positive diagnosis. Recommendations have been offered by expert groups on both the scaling up of contact tracing and ensuring ethical implementation of such measures. One state has passed legislation establishing an oversight framework for state contact tracing and associated data collection and use. Legal challenges to interstate quarantine rules have, thus far, been unsuccessful. Recommendations include: appropriating federal funding adequate to mount and sustain rapid, comprehensive, culturally-appropriate state and local testing, treatment, contact tracing, and supported quarantine and isolation service efforts; building contact tracing systems that cover social as well as health care supports for those affected; and, to bolster trust and participation in public health efforts, implement contact tracing-related health communication efforts targeted to reach the diverse array of communities affected by the epidemic
