Casual- Noone washes their hands, research doctors don't work, sick people given hugs
Normal- 2/3 of people wash hands, doctors work 3 days a week, sick people ignored
Brutal- Compulsive hand washing, doctors never go home, sick people locked in prison.
I suspect the real world is closer to the casual difficulty settings than either of the other two.
