Epidemic (SIR)
Every dot is a person wandering around and bumping into neighbours. Green folks are susceptible, red are infected, and blue have recovered with immunity. Click inside the box to start an outbreak, then change the rules and watch the curve on the right rise and fall.

What to try
- What happens to the peak of the red band when you switch from Normal to Lockdown mobility?
- How high does the vaccinated fraction need to go before the outbreak fizzles out on its own?
- Does a longer contagious period make more people sick overall, or just draw the epidemic out?
- Can two outbreaks happen at once if you infect people in two far corners of the box?
- After the epidemic burns out, why do some green dots survive even with no one vaccinated?
