    It's not a disease, but an insect infestation. Those bumps are sucking insects.
    I'd use something like Sevin, fast. Or, what might be better for the plants in the surrounding areas is to get rid of those plants.
    Just my opinion, someone else might have other advise on how to get rid of them.

    Eew. Yeah, those are bugs; the ants are hanging around because the sucking insects excrete excess sugars (that they're sucking out of your plant) as a sticky "honeydew" substance that the ants love. They'll even "farm" groups of aphids, protecting the aphids and collecting the honeydew. [Note: I don't know that these are aphids; they may be some sort of scale?]

    Can you scrape the bugs off? If so, a stiff blast of water will get rid of them pretty quickly, though it will need to be repeated daily for a while, as eggs already laid will hatch and start eating. (The bugs you spray off won't find their way back to your plant).

    If you can't scrape them off easily, then you'll have to do as Barb suggests and spray the plant with a systemic insecticide.

    Good luck!

    Yeah, scale. (See link below, and scroll down to pests).
    This site discusses what to do when the scale is on a dormant plant; you may need some other treatment since the plant is still trying to produce leaves, I'm just not sure.

    If you have a county extension office available give them a call.

    Best,

    use a systemic pesticide that will kill any sucking insect.
