"The Community Infectious Disease Alerts Service (CIDAS) is an attempt to address privacy issues across a broad range of communities when we need to exchange sensitive information between systems (with appropriate consent). This information could include homeless status, substance use, mental health challenges, and health conditions. The communities could include homeless shelters, rehab centers, assisted-care condominium complexes, schools, universities, corporate campuses, churches, or even tight-knit social clubs. So, when a community has a vested interest in being alerted if a community member becomes ill, how can it be alerted without revealing sensitive data in the process?

"This following demo was created for a Project Unify user story in which a client, Sarah Thomson, is scheduled to check into a homeless rehab facility and is required to take a COVID survey. Having exercised her 42 CFR Part 2 rights to not share her substance use disorder with anyone, including her primary care provider, the problem is how to alert the rehab center of her potential COVID infection without revealing her substance use disorder. The Community Infectious Disease Alerts Service is used to aggregate her rehabilitation community with many other communities to share (subscription) her COVID status (with appropriate consent) without compromising her sensitive information."
