It would be clearer in the examples if you used the names of the germs, not just the generic 'same type', and 'Once infected with a germ type or color, the player can "spread" a germ card of a matching type or color' would be more clear than "Once infected with a germ type or color, the player can "spread" a matching germ card". It's inherently confusing that the same germ can cause each different color of infection, and each color of infection can be caused by different germs. A more specific term than "type" would help: 'strain' or 'species', perhaps, since many will think "type" could refer to color, too. Should be noted that it's only YOUR OWN cards of the color of your choice that are cured by the Rainbow Antibiotic (or is it?). Nice touch having different flesh tones for the handshake card.
