Not really. I very rarely get this and each time it seems to be from fresh cut frag. I was never contagious in my tank but since it's mostly on fresh cut frag coming from somebody else I am guessing that only the corals that are weak or slightly dammaged are susceptible to this type of bacterial attack.
I am guessing (only my guess) that when it is affecting many corals at once it might be more related to water quality maybe?

Have you ever found RTN to be contagious in your tank?
