 The model of COVID-19 in correctional facilities is contained in the Microsoft Excel spreadsheet `COVID-19_Incarceration_Model-v2.1.xlsx`. This spreadsheet model builds on the spreadsheet developed by [Recidiviz](https://www.recidiviz.org/) (original spreadsheet model available [here](https://github.com/Recidiviz/covid19-dashboard)). It was developed with funding from [Corrective Services NSW](https://www.correctiveservices.justice.nsw.gov.au/) and [Justice Health and Forensic Mental Health Network](https://www.justicehealth.nsw.gov.au/).

In particular, version 2.1 improves the approach used to model vaccination to account for sterilizing immunity.

 The aim of the model is to track an outbreak of COVID-19 in a correctional setting and assess the potential impact of prevention strategies and interventions. The main directory contains a blank spreadsheet model ready for use. Example spreadsheets with inputs and outputs are available in the `Examples\` directory. A short manual `COVID-Incarceration-Manual.docx` provides further user instructions and details of the interventions incorporated into the model.
