An online health-monitoring system for COVID-19-infected patients who are staying in hotels and homes was developed using geographical information systems. This system provides display functions for sending health observation forms to infected residents, scoring for medical risk assessment, and centralized management. More than 1,146,000 health observation records were registered in November 2022, and the system contributed to maintaining the functionality of the municipal health center in Sapporo, Japan.
