I have a FB friend who's little guy, about 7.5 mo, has a weird rash. She took him in yesterday and the Dr said it was viral and there was nothing they could do for him. I looked up Roseola (cause I heard of it around here) and it says it's caused by a virus. He didn't have a fever until today.
Here are some pictures that she has posted. Started on legs and belly and spread from there. What do you think?



She seems to have ruled out allergy unless they don't show up for more than 24 hours. No new detergent, has not introduced any new foods. She has been giving Benedryl every 6 hours with little change.
Moms who have been through this, what do you think? How long does it last? Any other thoughts?
Re: Who's baby had Roseola or other unexplained rashes?
Ava had somethine very similar, but it was eryothemia multiforme minor, a very bad reaction to amoxicillin.
any chance he's been on anti-b's?
I just asked her, she said Nope.

Roseola is characterized by a suddenly high fever (like over 102 and sometimes higher) with few if any other symptoms that lasts for about 4 days. The rash appears 24 hours after the fever breaks. So while the child has the fever it is a big mystery and then an a-ha! moment when the rash appears.
My son had it when he was 14 months old and he was very sick. Like two trips to the ER in one day sick. He had a very bad case apparently as most kids just get really hot and lethargic and lose their appetite (check, check and check) but DS also had vomiting, diahreah, and fever induced seizures. We didn't realize it was roseola until the rash appeared on day 6.
Given what you've posted it sounds like your friend's son has something else since his rash came before the fever. Keeping him comfortable by treating the fever and the rash with something soothing may be the best they can do for now.
Ditto what a PP said. Reed had roseola and he had a fever for about three days, then fever broke and he got the rash. And it was definitely more like sprinkles. His was only on his torso too, not on his face.
