Ouch! Is this a virus??!!

[kbdsyd]

Hello all.
I recently purchased a Catt via Ebay (Yeah, yeah, I know, but before you say it), from a reputable seller.
The orchid I received had an interesting mottling to one of its leaves; otherwise a very healthy looking plant.
Can anyone advise whether or not this is a virus?
Image 1 is front of leaf; image 2, the back . . .
If so (gulp) do I destroy it?
If not, are there measures to take to eradicate what ever it is?
How do I test for a virus?
Thanks for any advice/info!
