Virus transfer questions

[Tim P.]

I had purchased a group of chids from a grower recently, and upon getting them home, I noticed one of them had severe ring spots on the leaves. (Phrag Pearcei). It was in a box with other orchuds, not individually wrapped. The pearcei had leaf contact, and a few of its leaves were either kinked or broken in transport. Do I need to be concerned about the other plants in the box contracting a virus? What would you guys do to mitigate the risk to an existing collection? Really not wanting to throw the lot away. Currently quarantined from the rest of the collection.
Thanks!
