Would someone please answer my chicken pox question?

[Allabouts]

DNiece 2 has chicken pox, DNiece 1 does not because she's had them before. It's the school holidays and her mum is quite poorly with a virus so DNiece 2 is stuck indoors bored.

If I take DNiece 2 out/to my house, will my DS get chicken pox even though she herself is immune to it?

I know, she can't really get it again etc but could she still carry the virus/infection from her sister without having it herself?

My head is telling me that's not how chicken pox work.

Thank you

Is it DN 1 (previously had CP) or DN 2 with active CP who you are thinking of having to your house?

DN 1, having had it before, has the virus dormant and is not going to spread it. DN 2 is actively shedding the virus and your should not expose your son to her.

Miss Sorry, my OP wasn't clear.

I meant DN 1 (the eldest) who's had chicken pox, is who I'm considering taking to my house

The younger one is the one with chicken pox

They won't catch cp of the girl who's had it before

You have to have chicken pox to pass it on.
So no, your DC won't catch it from someone who's already had it.
