So it turns out that Jet's rash is actually from the tail end of roseola. Looks like he got it either in or on the way to or from San Diego. The symptoms are mostly high fever, the mild diarrhea, heavy eyelids, light sleep, stuffed nose, and when he's all better, the rash comes and goes in 24 hours. So we've actually gotten through the worst of it, though we couldn't know, as a lot of things break out in a rash when a problem's beginning.

Kathryn had a good call, in that often an anti-biotic allergic reaction has a rash and the congestion, but we hadn't given him any. I'm just glad to know that it's not a food allergy that is this virulent.
