COVID-19 Contact Tracing: COVID Alert CT Summary by Week - ARCHIVE

Published by data.ct.gov | State of Connecticut | Catalog Last Checked: July 07, 2026 at 09:16 PM | Dataset Last Updated: August 02, 2023
Note: This dataset has been archived and is no longer being updated. COVID Alert CT is Connecticut's voluntary, anonymous, exposure-notification smartphone app. If downloaded, the app will alert users if they have come into close contact with somebody who tests positive for COVID-19. This dataset includes the cumulative and weekly activations for COVID Alert CT for iOS and Android smartphones. The location of app users is not tracked--the app uses Bluetooth technology to detect when another person with the same app comes within 6 feet. The phones exchange a secure code with the each other to record that they were near. The number of codes issued and claimed is also included in this dataset. Data presented are based on a weekly reporting period (Sunday - Saturday). All data are preliminary and are subject to change.
