Location interaction tracking system

A method of using an interaction tracking system comprising:

• accessing the system by a first user computing device and aggregating anonymous first user identifier gathered from the first user computing device;
• accessing the system by a second user computing device and aggregating anonymous second user identifier gathered from the second user computing device;
• indicating by the second user computing device that a user of the second user computing device has been labeled as confirmed positive and label the aggregated anonymous second user identifiers as confirmed positive for a prescribed time period;
• determining that the first user computing device is within a prescribed distance of the second user computing device during the prescribed time period in response to receiving aggregated anonymous second user identifiers labeled as confirmed;
• displaying on the first user computing device an alert that the first user computing device was within the prescribed distance from the second user computing device marked as confirmed positive at least once during the prescribed time period;
• and
• automatically determining a hot spot based on the aggregated anonymous identifiers from the first user computing device and the second user computing device, wherein the hot spot comprises a predetermined number plurality of historical paths of travel of the plurality of user computing devices are within a predetermined distance of each other during a day and time of the predetermined past time period in response to receiving a signal from each of the plurality of user computing devices.
