Lc. Yung Hua 'Bourdette' virus?

[pbphut]

I have a Lc. Yung Hua 'Bourdette' growing in S/H and seemingly doing well, but I'm noticing spots on the new growth that the older leaves don't have. Does this mean I have picked up a virus? Should I destroy the plant to keep it from infecting the others, or are the spots a natural manifestation on a more mature plant? I'd hate to get rid of it, as it has two sheaths that haven't bloomed yet, but I will if it will put my other 'chids in jeopardy.
