CalPROTECT (California Prison Roadmap for Targeting Efforts to Address the Ecosystem of COVID Transmission) is a multidisciplinary initiative that includes public health experts, clinicians, and scientists in behavior, environmental engineering, and economics at Amend at UCSF, University of California, San Francisco and University of California, Berkeley. The project aims to collect information on how COVID-19 is transmitted in CDCR/CCHCS facilities and integrate into that knowledge the experiences and perspectives of correctional and facility staff, medical staff and patients to give correctional leaders and policymakers the scientific evidence they need to optimize the health and dignity of those who live and work in CDCR facilities during the COVID-19 pandemic.

Given the rapidly evolving understanding of the novel SARS-CoV-2 virus and disease (COVID-19), CalPROTECT and its partners may not revise all publications and resources as new information becomes available. It is important to note that each of our reports are based on the most updated research at the time of writing. We encourage continued engagement with public health and medical communities regarding how best to implement the most updated recommendations based on science and evidence to prevent and manage COVID-19.
