Is this some type of virus? What do I do about it. I only grow sunflowers very occasionally and have never run into this. What do I do about this? Thanks.

Maybe rust?
Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn, that mankind are more disposed to suffer, while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed.

Believe for rust you can prune the leaves out and dispose of them. Disinfect your pruners with some bleach. If possible keep the moisture down.
