hello, as you can see, this is a simulation of the coronavirus The simulation begins everyone is normal (light green) but there is a coronavirus carrier (red) who can contaminate a light green by touching it the light green then becomes red but fortunately there are doctors (the number may vary ). When a doctor (light blue) touches a red this red turns dark green this means that he is immunized and that no red can contaminate him but this will not last long (20 seconds) he will turn back to light green which can become contaminated. The goal is that there should be no more red. If there is no doctor click on the green flag again Update - doctors have one in 25 chance to be infected - dark greens have a one in 25 chance of becoming a doctor - speed reduce
