Overview

The Novel Coronavirus COVID-19 contact-tracing app (COCOA) and Digital Agency

The Coronavirus COVID-19 contact-tracing app (COCOA) is an app to prevent the spread of COVID-19 pandemic, but problems such as delays in resolving problems have occurred immediately after development. In order to quickly resolve problems and improve functions, a cooperation team between the Information and Communications Technology (IT) Strategic Office of the Cabinet Secretariat (at that time, currently Digital Agency) and Ministry of Health, Labor and Welfare was established in February 2021, and has been engaged in the development, maintenance, and operation of COCOA.

COCOA stopped the contact notification function in November 2022 because the number of people who can register positive results was limited and the premise for using COCOA changed due to the review of the notification of all cases in COVID-19 pandemic.
