Sara Alert™ is a standards-based, open source tool that allows public health officials to monitor individuals at risk for COVID-19, enabling real-time insights and increased reporting capability for early containment of the virus.  The tool allows individuals to report daily symptoms through web, text, email, or phone calls. The tool was developed by MITRE in partnership with state, local, and federal partners and is currently helping nearly 5,800 public health users cumulatively monitor over 300,000 individuals.
