How to play:
You can try to infect people around you by clicking an area to cross a road. Your aim is to spread the disease to another city by getting it on the bus.
You cannot spread the disease across a road with a resistant person nearby because they have a natural resistance to the disease so they can't get ill and spread it.
You cannot infect vaccinated people because the vaccine helps their body make the right type of white blood cell to fight off the disease.
Key:
= Infected
= Resistant
= Vaccinated
