I was planning on my brother and sister in law coming to visit next weekend (they are 15 and 4). My b.i.l. (the 4 year old) had a sv a wekk and a half ago. It only lasted one day. By the time he comes it will have been 2 1/2 weeks. I was feeling okay about that, but I just found out that it was going around my s.i.l.'s work (the 15 year old) last week. 3 people got it - 2 with just n* and one with v* (don't know about d*). My s.i.l. didn't get it, but now I am worried that she will either carry it or get it while she is here. It's a week away - do you think that's enough time to be safe?
