yes It does I went to a imperial camp in the reach trying to talk to legate Rikkie but then a bear attack a imperial solider than in one of his attack he got light for a second (I think he has rockjoint) I went back to a save and it always does that so I think that they can get the disease but I'm wondering if I could cure the rockjoint for him or no

sorry for the edit
