Yeah, the unrelated disease hypothesis does make sense. Diana would tend to have a cure, being in a giant arboretum/wildlife preserve and all. It just seems kind of convenient, though Harold does have a history of that sort of thing.
A bit of explanation for my thought process:
---------
At first I figured that the tree was infected with Limit, but Harold's immune system (and the Tree) were able to keep it down at a low enough level that they weren't readily communicable.
I based that extrapolation upon the effects of the Nutrient Paste on the Plague. In combination with a guess that since Harold wasn't directly exposed to FEV (i.e. dipped), maybe he wasn't entirely immune to Limit.
Wrong, though.
---------
Then I had a brainwave: What if the "New Plague" were a
mutation of Limit-115, which would explain why Harold didn't die quickly. His FEV-boosted immune system allowed him to fight it off to an extent because of its similarity to Limit, but not completely.
However, that wouldn't explain why Diana would let him into the Nursery, and it wouldn't explain how she could have a cure before she ever invented it.
So I scrapped the idea of Harold being infected, but not the general mutation concept.
---------
So there's the conclusion that yeah, it most likely was an unrelated illness Harold's tree was affected by and that Diana was able to cure, though for some reason I find that kind of disappointing. I guess I was looking for a deeper connection to the plague theme, even though that makes no sense. As you pointed out.
It actually does reinforce something was saying earlier, though. Harold's a Deus Ex Machina (classic definition) to a literal Deus Ex Machina (Diana for Twin Mothers). Chalk up another addition to Van Buren's considerable roster of thematic irony.

As for Limit 115/New Plague, as far as I know they're the same thing.
It seems the nickname "The Blue Flu" is valid as well. I'd wager that's what most pre-war people called it, seems like your typical descriptive colloquialism.

It's just that Limit 115 was the codename under which it was developed at Boulder while New Plague is the public name it was given when it leaked out and started spreading across the US.
Let's see what ZAX has to say:
ZAX said:
"Discovered in 2053, the New Plague was a socially transmitted plague that killed an approximately twenty thousand human beings in the United States, including cities such as Denver, Colorado, Boulder, Colorado, and Colorado Springs. The time of death from identification of symptoms was three to five days. "Symptoms included many symptoms in common with the flu or chest cold, and eventually resulted in clogged respiration, killing the infected subject.
"The discovery of the New Plague resulted in the 2053 quarantine, and several emergency programs were established to find a cure for the plague. The Boulder Dome has limited information on the New Plague, since it was not one of the research concerns in the Boulder Dome. If you could find a medical research database concerned with the New Plague, or provide me with holodisks related to the New Plague, I could provide you with more information.
"The only way we could fight off the New Plague was by creating better humans."
I don't think Limit 115 was a US project. It seems kind of odd that the USA would develop a disease, accidentally release it, and then start a project to control it almost two decades after the first onset? (remember the Glow holodiscs) It seems unlikely it was naturally occurring, either.
Thus an idea: Maybe it was the Chinese who developed Limit 115?
And now, back to an earlier idea:
Many serums and antibiotics were developed but they only seemed to generate a temporary reprieve, as it came back in different forms that affected survivors of the previous outbreak. Much propaganda was created about hygiene and inoculations, and that helped slow its progress. Outbreaks occurred in 2053-55, 2062-63, and again in 2077. Can go dormant in the cells, only to break out later, making seemingly "cured" people into carriers. Original versions didn't seem to cause sterility.
So Limit 115 mutated several times before the war. This adds credence to my idea of New Plague being a mutation of Limit 115. The New Plague being the most recent incarnation (in 2077) before the Great War breaks out (also in 2077).
All the previous incarnations can technically be referred to by any of the three names, from what we can see. One is scientifically correct (Limit 115), one is a colloquialism (Blue Flu), and the other seems not to fit in. It would if the "New Plague" name only referred to the most recent variant, though.
The nomenclature makes a bit more sense this way. It doesn't make much sense for a disease to be called "New" for 24 years, hence the "New" plague is just the most recent variant. (Look at me, trying to retroactively reorder chaos)
The plague's ability to lay dormant for so long and its shifting nature (repeated outbreaks, even amongst supposedly "cured" people) suggest that it was engineered. Since it seems unlikely it was a US project, that suggests outside origin. Since China was the main outside threat to the USA, China's the most likely suspect.
It would interlock with the "Red Scare" theme of Communist Insurgency in the tutorial very well. The Chinese were the new Soviet Union. The Soviets were heavily into research on diseases, so it stands to reason the Chinese would be too.
It's my bet that in Fallout's timeline Chinese agents in the USA started the initial Limit 115 outbreak, and probably helped the subsequent ones along as well.
That would add even more thematic irony, in that a scientist of Chinese descent (born in San Francisco) becomes infected with the New Plague at the Boulder Dome.
