Highly contagious infections of the fins and/or tail by bacteria is called "Fin Rot" are common in discus fish. These bacteria will normally infect the tissue of the discus that have been damaged by an injury, poor water quality, or a more severe parasite.
A common cause is a very high pH in the aquarium water. This high pH could burn the fins and tail. The discus's fins will become cloudy, then they will become inflamed, then begin to flake off. If this condition goes untreated, the fish will die.
To avoid fin rot, it is best practice to maintain good water quality. Poor water is full of fish waste, which in turn encourages the bacteria growth that causes fin rot. Make sure you keep up your water changes, and constantly make sure the quality is correct for discus.
