Virused plant?

[NYCorchidman]

Can you tell me what types of virus the test will pick up? I heard a lot about the names like CMV and ORV, but I recently read that there are over 40 virus that affect orchid plants, which left me totally OMG!!!!
I wonder if that means at least 40 something different symptoms as well. so much headache!

The funny thing about virused plant is some of them grow perfectly fine with no symptoms and only when it flowers, it shows. I tossed one cattleya this summer. It grew so well with nothing ugly on leaves, then when the flowers opened, there were thoses dreaded color breaks. I was so disappointed.

Now this oncidium intergeneric I have grows and flowers like crazy. The flowers do not show any symptoms (they are quite small so even if they did, it wouldn't cause much cosmetic damage), but the leaves are ugly.
Yes, everytime I look at the leaves, I'm not happy. Is touching the leaves with bare hands and then touching other plants with the same hands going to transfer virus?
I'm all paranoid now!

It seems like many of the intergenerics have some issues with leaves. At least that's how I feel. I love to see clean green leaves, but when I see anything at all other than green on it (except for naturally mottled ones), I get all worried.
I will post pictures of some of the other plants leaves I am worried. They might be normal, but then again, I'd like to hear what others have to say.

Thanks again.
