COVID-19 affects everyone - but different countries and different people need different precautions. Using machine learning and a bit of maths magic, we’ve modelled how the coronavirus might spread in your community.

As the virus infects your region, see if you can use tools such as social distancing or school closures to prevent the disease from spreading. However, be aware of how local factors such as transport coverage, public fear and the economy might affect the effectiveness of your actions. (Hint: timing according to metrics is important!)

We hope you enjoy trying out our team’s submission for Code Jam #9, and gain a better awareness of coronavirus prevention! Spread the word, not the virus.

Please allow location access for the best possible experience - we're trying to drive the point home (literally). Additionally, the API limits the number of requests per second, so please keep that in mind if there are many people playing at once!


As good as Plague inc

@FrenchBoi12755 can you link the program? Like is it for diagnosing people?

FrenchBoi12755 (4)

@generationXcode Sure! So the program has diagnosis points, and you're supposed to count it! But of course, you cannot be 100% sure you have COVID. It's only for seeing the probability that you MAY have COVID-19. Link:
