How on earth has my DS caught chicken pox?

[habibihabibi]

Just done an online consult with GP as my DS (10) is covered in spots and has a temp. Dr said it's chickenpox.
DS has been nowhere but the house and garden for 10 weeks.
Nobody has visited
DH and I both working from home and only been out to do weekly shop (alternating)and I took younger child once to the hospital appt 2.5 weeks ago but he has no spots.

Also both kids have been vaccinated for varicella as tots.
I am really puzzled.

I'd be inclined to think it isn't chicken pox, especially as he's been vaccinated. Viral rash? Has he been playing outside?

It’s probably not chicken pox then, was it a video call?

My son had chicken pox and it took 3 weeks for his little brother to come out with it.

1. he’s been somewhere/seen someone you don’t think he has- any bike rides round the block on his ‘own’.

2. you or the other DC brought back the virus asymptomatically from the hospital

It sounds like it probably isn’t chicken pox.
Do you have a hot tub? Paddling pool?

I would suspect the hospital visit. You or the little one brought it home with you.

I think chicken pox has 21 day incubation period.

Even with that incubation period, the chances of a vaccinated child catching it are very low, so that's two very, very unlikely scenarios stacked on top of each other.

What do the spots look like?

I agree with hot tub/paddling pool contamination.

Are they vesicles?

They look poxy.

Hot tub?

He has been in our pool the past week but I am militant with clorination and anti algae stuff, testing it daily but I think its more likely from it than the pox.
The GP did a video call and said some times even vaccinated children can get a mild dose.

habibihabibi we are extremely careful with ours too but DD (4) got some spots. Hers looked very chicken poxy too but she’s already had it (and we also haven’t been anywhere!) so came to the conclusion it was hot tub Folliculitis.
Hers disappeared after 7 days.

We though dd had chicken pox but she had these it's very similar. It can come and go varying in severity for years..... then just suddenly stop.

Molluscum tends to be more fleshy coloured that yellow headed/poxy.

Yes I have dealt with molluscum before. These are more chickenpox looking. What did you use to it clear up Drivingdownthe101 ?
I have just given the pool a double chlorine shock.
It is very warm here ( Saudi) so perfect breeding for bacteria.

I used oilatum in the bath and put Aveeno on, I don’t know if it helped but she didn’t scratch them and they cleared up fairly quickly.

Maybe you or your husband have shingles without realising. People can get chickenpox from someone with shingles.

And you don’t have to go out to get shingles, it’s the virus that’s already dormant in your body that comes out of the nerve endings and causes shingles.

I think the chances of them having shingles without noticing (shingles are painful) and then passing them on to a child who has been vaccinated against chicken pox is fairly slim.

The little one could have picked it up and had it very mildly eg two or three spots that you didn't even notice, but been enough to pass it on to the older one. Should be less severe due to vaccination, vaccine immunity does tend to wane over time to varying extents. Hope your DS feels better soon
