Mint disease?

[Island]

Hi,
I was just in the garden, and I saw that a lot of my mint plants have orange spots on them. Is this some sort of disease? If so, do I need to get rid of those plants and start fresh?
Thanks!

Here is about a 4-5 page pdf from Washington State University on mint diseases. I am guessing that it is rust because of the color described. The treatment is an organic approach.

I have a number of mint varieties here at home and have, honestly, never noticed any disease problem. Good luck
