Yes, your rose's leaves are exhibiting typical symptoms of Rose Mosaic Virus (RMV). It's passed on by propagation. An infected bush will pass it on by grafting or cuttings.
The only way it can be cured is by heat treatment, a costly process that can kill the plant and not something you can do at home. If the original seedling is grafted onto an infected rootstock, all succeeding plants from that bush will be infected.
It may not affect the plant except in the mosiac pattern of the leaves, or the plant may lose vigor and bloom production. It's not suppose to be infectious to other bushes but some say it can be spread by root transfer. Many roses in commerce have it. I have some that show symptoms but the vigor of the bushes are not affected. It seems to affect bushes in warmer climates than those in cooler ones. If your rose grows and blooms well, let it be.
avoid roses from big box stores. Most of their stock comes from the Tyler Texas area which is notorious for RMV infected bushes.

thanks.
That's what I thought, but hoped not.
I guess I'll just wait and see how well they grow this summer.

Is this something that can just happen one year if it was healthy (I think) the prior year?

erika, it is my understanding that symptoms of RMV sometimes don't show up for several years; so, yes, it's something tat can just appear on a bush that seemed healthy previously.

I have a Zephrine Drouhin that shows very mild symptoms of RMV only on a couple leaves. To me, that means the plant stays as long as it continues to be healthy. It also means, to me, that if I think another plant would do better in it's place I will not hesitate to dig it up and move or dispose of it.

There are rose suppliers who offer many seltions of plants, all virus-indexed. Maybe you don't want to wait and simply want to replace the shrubs now.

We've had plants that grew here for years, before the signs showed up.
In one case, it took 20 years!
When it finally happened, we weren't surprised.
We'd always known that the plant must be virused, considering the source, and the rootstock,
but that much time passed before the symptoms appeared.
WE see the signs most-commonly in a cool spring, and the symptoms disappear as the weather warms.

There are other roses here, which -- considering their provenance -- are almost certainly virused,
but we've never seen it.
