So, he's at the blister stage at the moment, and I've read he is infectious until 24 hours after the last blister has crusted over. Some are crusting, some have turned up only today.
I'm trying to decide what I can actually do with him in the way of holiday activities. He's only feeling mildly sick, and is physically fine to come on car trips etc.
So do I have to limit him to things such as say going on a bush walk where the chances of us meeting any people is minimal, or do I have to strictly keep him at home for the infectious period?
