Contact Tracing Mechanism

Once location data has been captured and saved, as shown in text_database, this could be analyzed to enable contact tracing. You just have to declare the COVID-19 affectee's name (ss your contact list consists of names, this could be just a simple phone/mobile number, it will work on that too).

The algorithm will ask the following parameters

Patients ID

The name or phone number of the person that you declaring as infected with COVID-19.

Enter Time Difference for Backward Check

The period of time in a patient's travel history you want to consider at a given moment with other people. If you don't understand what it is, just declare it 1. Here the unit is minutes. The Maximum you can enter is 59 min. Here, the value is 1 min.

Enter Distance Range For BACKWARD Check

The radius of the circle of the distance within which people have come in/interacted with him/her. If you don't understand what it is, just declare it 1. Here the value is in meters, i.e., 1 meter.

Enter Time Difference for Forward Check

Same as previous but this time, algorithm checking is forward. If you don't understand what it is, just declare it 1.

Enter Distance Range For Forward Check

Same as previous but this time algorithm checking is forward. If you don't understand what it is, just declare it 1.

This algorithm will give you the results of the 1st iteration check, i.e., if you consider the COVID-19 spread like a chain so the 1st iteration means the list of 1st IDs/Persons who have come in contact with the patient i.e., 1st interaction. if you enter one of the IDs from the list generated, you will get the later part of the chain (2nd iteration check).
