I do not think anything will prevent the sickness if they are going to be caught by what ever it is. The salt may stop the accumulation of fluids in their tissues but you will have to be careful as the Aquarium salt will remove some fluid from the bodies of the healthy fish and could dehydrate them a bit. The saline balance in freshwater fish's bodies is kind of touchy.
