Please save my violacea seedling! Severe chlorosis

[cavycat]

Update:
VIRUS?!

The seedlling eventually lost both of its bigger leaves. The smaller one seemed to be stable for a while, then it suddenly developed yellow markings. I think it happened the day I put it in a slightly warmer spot. The pattern seems virus like to me. Do orchid viruses respond to warmth? I'm now extremely paranoid that my other orchids may have caught it.
I threw what was left of the orchid away. By the way, the meristem was completely brown/rotted/dead.
Please have a look at the pictures and tell me if you think this was a virus.

Thanks
