Should i say goodbye to this Catt?

[Pat'sCatt's]

Hi everybody,

Just read the post from mrhungx about a virussed Catt, so it always makes you doubt some of your own plants. This picture is my Cattleya loddigesii, and as you can see it has also a lot of black dots on mostly the back of the leave. Can anyone tell me if this is most likely a virus, or could it also be fungal?

Or in a shorter version: treasure or trash?
