Mitigation through on-site testing & education among formerly incarcerated individuals against Covid-19 - The MOSAIC study: Design and rationale.

Background: Many of the largest COVID-19 outbreaks in the United States have occurred at carceral facilities. Criminal legal system (CLS)-involved individuals typically face structural barriers accessing medical care post-release. Improving COVID-19 testing and education for CLS-involved individuals could improve health outcomes for this vulnerable population and the communities to which they return.
