Hi
I just thought i would give you some facts regarding chicken pox
The incubation period ( when you could be harbouring the virus is 10-21 days)
usually an individual will be infections for about 2-3 days before the first spots appear and will remain infectious until last spot has started to dry up usually around 5-7 days.
Children can have varying degrees of symptoms from a few spots to being covered and generally feeling very unwell.
I think If you are about to fly on holiday it is a sensible precaution to limit the chance of catching this infection because you will not be able to fly if weeping spots are evident and horrible if your child feels unwell. However you can't prevent someone from catching it, just minimise the risk.
If your child has chicken pox and spots are evident on the day before flying even if they are dry it would be sensible to get a docors letter to autherise that your child is clear to fly. Airlines are strict about this, and rightly so.
Speaking from experience my son contracted chicken pox whilst in Florida he also suffers from eczema so his chicken pox were severe however we tried not let this ruin our holiday and took sensible precautions by letting him nowhere in close contact with other people so theme parks and swimming out for a while but we still went out and played football , had picnics etc.
(also required Drs letter before flying back home not that easy to obtain on a sunday afternoon.)
Hope that this info has been of some use
