COVID-19 Contact Tracing

Help Slow the Spread

Enter your location below, as a number from 1-100. Your default location is 1. You may repeatedly enter numbers below to simulate moving around the city. After updating your location, you may visit the Exposure History tab to see the updated map.

No one near you is detected to have COVID-19. Still, remain cautious and keep your social distance!

Map of the city as a string of numbers (0 is uninfected, 1 is initially infected, 2 is possibly infected by you, 3 is your current location):

3000000000000000010100000000000000000000010000100000111100001000000000100000000000010000000000100001

This simulation assumes that infected people don't move around, and that you are the only pereson who is able to move around and transmit the disease once you catch it (meaning infected people can only infect you and not others). Website tested on a 1920x1080 screen, other dimensions may look distorted.
