Normally lilium lancifolium (tiger lilies) are very resistant to virus so are you sure it is virus and not just root damage, or insect damage ? I guess individual bulbs could have virus, but it is not all that common.
Just don't want you to pull any bulbs which do not have virus.

To answer your question: Bulbils would carry any virus if indeed it is virus.

Hi Kenneth:

Sorry, I should have had a photo. Check these out.

Second odd or diseased tiger

Are the odd ones infected with the dreaded lily virus?

Ok, that explains it. It is not a tiger lily (lilium lancifolium) but an asiatic lily. This asiatic lily has recurved petals and nodding flowers and thus could look a bit like a tiger lily, but it is not a tiger lily. Very handsome, though.

This one definitely have tulip breaking virus (TBV) and should be pulled and destroyed immediately.

Hi Kenneth:

Thanks for the update. These were labeled Lilium (Tiger type) 'Twinkle' mix when I bought them. Sadly, there are at least three I have to destroy, maybe more.

Better now than to lose all of them.

Thanks,
MG

The first picture looks like a healthy lily. The remaining look infected.
