Get DC's free DC COVID Alert Notice (DC CAN) to help protect your community while protecting your privacy.
How It Works
Public health authorities around the world are building apps that use the Exposure Notifications System to help their contact tracing efforts.
DC CAN uses Bluetooth Low Energy (BLE) technology to quickly notify users who have likely been exposed so you can reduce the risk of infection for your friends and family and help DC stop the spread.
STEP 1
Let's get started:- For Android devices, you can find the app on Google Play. Android users will also receive a notification from the Play Store.
- For iPhones, opt-in to Exposure Notifications in your device settings.
STEP 2
Once you opt-in to the notification system, the Exposure Notifications System will generate a random ID for your device. To help ensure these random IDs can’t be used to identify you or your location, they change every 10-20 minutes.
STEP 3
Your phone and the phones around you will work in the background to exchange these privacy-preserving random IDs via Bluetooth. You do not need to have the app open for this process to take place.
STEP 4
Your phone periodically checks all the random IDs associated with positive COVID-19 cases against its own list.
STEP 5
If there’s a match, you will receive a COVID-19 exposure notification, with further instructions from DC Health on how to keep you and the people around you safe.
