The target contracts one of the following diseases: blinding sickness, bubonic plague, cackle fever, filth fever, leprosy, mindfire, red ache, shakes, or slimy doom. The Disease is contracted immediately (the onset period does not apply). Use the disease's listed frequency and save DC to determine further effects. For more information see Diseases.

However, the Disease is highly contagious, and any Creature that touches the infected target, is touched by the target, or spends more than an hour in a confined space with the target must make a save against the disease's normal DC (not the spell DC) or contract the Disease. If the initial target overcomes the Disease by making the required number of Saving Throws, it remains a carrier of the Disease for a length of time equal to the disease's frequency, and can continue to infect others during this time.
