Washington DC has fired up its own coronavirus exposure and contact tracing system utilizing the Apple and Google exposure notification framework — and doesn’t need an app on the iPhone.
The Washington DC system functions similarly to others seen in the past, including Pennsylvania’s COVID alert PA.
When someone tests positive for COVID-19, they are given an anonymized code via the health department. The code, when entered into DC CAN, will send alerts to anyone who has met the minimum threshold for exposure. Currently, the minimum threshold for exposure is met when someone is within six feet or less of an infected person for a minimum of 15 minutes.
Android users can download the app from the Google Play store. Apple iPhone users just need to opt into the exposure notification system, and turn on notification alerts for the Washington, DC region in their iPhone’s settings.
For those who travel frequently, DC CAN is interoperable with exposure notification apps from New York, New Jersey, Delaware, Pennsylvania, North Carolina, Nevada, North Dakota, and Wyoming.
