"Conditions" specifically refer to physical ailments, like bleeding, poison, deep wounds, disease, etc., and not to hexes, curses or enchantments - unless they create a condition when they are cast that can be spread.
For example, the Mesmer spell Phantom Pain causes negative health degen for 10 seconds, and when it stops (either naturally or by having the hex removed) creates a deep wound for a given period of time. If one casts Epidemic during the health degen phase of the spell, nothing happens; if one casts it after the deep wound kicks in, the deep wound is spread to any enemy in close proximity. Epidemic will not spread the Phantom Pain spell itself to others, only the condition created by it.
