Sara Alert™ Overview

Sara Alert™ serves as a force multiplier that supports governmental public health response to emerging disease threats, including active monitoring of home quarantine and isolation for disease containment or mitigation.  This open source tool allows public health resources to be directed where they are most needed. 

Sara Alert™ enables public health officials to enroll individuals at risk of developing a disease of interest (“monitorees”), for example COVID-19. Once enrolled, individuals can report their (and their household members’, if applicable) symptoms daily through multiple platforms (e.g., mobile, desktop, text-based, voice), providing public health departments improved situational awareness. If a monitoree reports any symptoms or does not submit a daily report, the record is flagged by the system so that public health can quickly and efficiently identify monitorees requiring follow-up for care coordination or non-response follow-up. Sara Alert™ also enables public health officials to enroll cases who require monitoring to determine when it is safe to discontinue home isolation. Once enrolled, individuals can report their symptoms daily through multiple platforms (e.g., mobile, desktop, text-based, voice), providing public health departments improved situational awareness.  If a monitoree reports meets a recovery definition or does not submit a daily report, the record is flagged by the system so that public health can quickly and efficiently identify monitorees requiring follow-up to verify that it is safe to discontinue home isolation or non-response follow-up. The concept of operations and high-level workflow are shown below.

Sara Alert™ Workflow

The Sara Alert™ system contains two parallel public health workflows that track two types of monitorees:

  • Exposure monitoring workflow: allows public health to monitor potentially exposed individuals to determine if they become ill; for COVID-19 the monitoring period is 14 days after the last day of exposure.
  • Isolation monitoring workflow: allows public health to monitor cases daily to determine when they preliminarily meet the recovery definition and it may be safe to discontinue home isolation.

RAPID IDENTIFICATION of a person requiring medical assistance, allowing a local health department to arrange a medial visit with minimal additional exposure.

SECURE INFORMATION EXCHANGE that protects individuals’ data and allows for real-time updates.

IMPROVED MONITORING of individuals through automated daily symptom checks via web, text, email or phone.

REDUCED BURDEN because public health professionals are able to more rapidly respond to individuals based on disease risk, prioritizing those who need help most.
