Exposure Notification (Contact Tracing) Simulator

This code runs a simulation of proximity interactions between a single subject and a collection of other handsets that belong to family, friends, coworkers, and other random people.

Disclaimer

The original Python implementation based on Apple + Google Contact Tracing by Gretel.ai - https://github.com/gretelai/contact-tracing-experiment

What's New

The simulation source code and this Colab have been updated to match Apple|Google Exposure Notification v1.1. specification April 2020.

How to Run

You can run the simulation in Google Colab here.

Press the PLAY ▶️button at every block of code and wait results.

You can set the simulation parameters for

Number of family members, friends, coworkers and others.
Simulation starting date

You can then download the generated report of the simlation pression the Download Report button
