So my husband is undergoing chemo. I have a cousin whose daughter has had chicken pox and it's been 2 days since the last blister has scabbed over. She will attend a birthday party that our daughter is invited to also. My cousin also has another kid who hasn't had the virus yet. Our 6 year old has been vaccinated against chicken pox. My concern is regarding the younger sibling who might be in the incubation period. My husband will not attend the party but Should I avoid seeing them until 21 days? It doesn't make sense as our children attend the same school and one way or another they will be in each others faces if not directly indirectly through other family members. We also have a 7 month old baby who is considered vunerable I guess. I could keep baby away from the little ones but would I be risking it for my husband. A little confused atm.
