My dd had chicken pox last week. We stayed in the whole week. It was VERY dull. I'm now waiting for my ds to come out in spots. So far there has been no sign. We have been avoiding baby groups and other places where I think there might be pregnant women and very young children. However, we have been to parks and also shopping.
Given that the incubation period is 10 to 21 days and he might have become infected on the last day of my dd's illness, to avoid all risks of infecting others in theory I might have to put ourselves in isolation for a month in total (one week for dd and then another three waiting to see if the spots come out). Would you put yourself into total isolation? Or would you just try to avoid "vulnerable groups"? Just go on as normal until spots appear?
Incidentally, we went on holiday for a week with a child who developed chicken pox (stayed in the same house, shared baths etc). I put us all in isolation on our return and neither of my two got it. We have had other numerous occasions in the past where the dcs have been exposed to a less concentrated extent and not got it.
