How do you tell if it's measles and not chicken pox or rubella?

[Guest guest]

Well, after saying on here a couple days ago that my son never gets sick, he got

a fever yesterday and just now I noticed spots on his cheeks and arms. The

biggest cluster is on his left cheek, and they are sort of running together

there, but the other places, they're not. They must have just literally popped

up, because they weren't there an hour ago. He still feels like he might have a

slight fever. He only ate breakfast yesterday and nothing after that. He felt

like he was going to vomit but never did. This morning he was starving and ate

a lot. He says he feels fine, but the spots just came out. I read in Dr.

Mendelsohn's book that there is no specific treatment for measles, rubella or

chicken pox except rest and fluids. He's acting like they don't really itch, at

least not yet. I guess I'm just wondering which of the diseases it could be.

He played at the park Wednesday, with a ton of kids that were there from the

boy's and girl's club, so maybe that's when he got it. I'm thinking I should

get it diagnosed, so I have it on record that he had at least one of the

diseases they vax for, but they'd probably be insistent about treatment. Any

ideas? Thanks,
