Design A Contact Tracing System

System DesignOnsite

Design a contact tracing system like we saw with COVID 19.

Have the mobile devices maintain a 2 week rolling log of encounters with others.
When someone says they got COVID, retrieve their logs and BFS from those logs with the logs of people they were in contact with. Use Cassandra to keep the logs of people who were i‍‍‍‍‍‍‌‌‌‌‌‍‌‍‍‌‌‍‍n contact.
