Track total minutes of close contact within a certain time frame #277

Feature description

Keep track of total time of close contact to infected within a certain time frame and add it to the risk evaluation.

Problem and motivation

According to CDC about 15 minutes of close contact to different people within 24 hours is equivalent to 15 minutes of consecutive contact to only one infected. It's specified as "Close Contact" on the following page.

https://www.cdc.gov/coronavirus/2019-ncov/php/contact-tracing/contact-tracing-plan/appendix.html

IMHO especially for people in jobs with a lot of short contacts like cashiers, ticket inspectors, receptionists etc. this could really add up during a day.

So if they have close contact to let's say 5 infected, 3 minutes each, they won't be notified of risk if the total time does not matter as single contacts probably where too short. Nevertheless the viral load would probably be pretty similar and so they should get notified that they are at high risk.

Is this something you're interested in working on

No

Hey @christoph-k

Thank you for the suggestion. I have forwarded your request to the developers by creating a ticket in our internal Jira (ticket ID: EXPOSUREAPP-4031). It will now be discussed by the development team and the RKI. Once we get any status updates on the issue, we will report back here on Github.
