3 of ds's friend have pox at the minute, he is fine so far, what I'm wondering is, if he gets it and his brother doesn't do I still quarantine until both boys have had it in the assumption they will pass between them or do I carry on as normal in the absence of spots?! I'm asking as they are infectious before the spots appear but I can't stay indoors for months waiting!!! Do I wait 3 weeks from first ds getting them then assume all is safe? Any advice welcome
