What is this rash please?

Would it be chicken pox or something else? It just appeared last night after school. She seems fine apart from that so far. Thanks

Looks like a viral rash, has she had a cold or anything recently? It doesn't look anything like chickenpox to me.

Yes she does have a slight cold. Thanks

Definitely not chicken pox.

I agree it looks like hives which are commonly caused by a virus in young children. But obviously might be a reaction to something else.
My DD kept getting them quite badly, and because DH has an anaphylactic allergy we ended up being referred to the hospital to make sure it wasn't an allergy thing. We were told it was very likely to be viral. It's not been an issue for a few months now.
