I had a friends birthday party for my daughter on friday afternoon. We invited all of the girls from the class plus a few others. When I went to pick up my dd at school, she told me that there were 6 girls in her class were coming to the party because 2 were sick. One of the girls had missed both Thurs and Friday.
When the kids start showing up, I see a car pull in my driveway its the girl who missed school the past 2 days plus her 2 sisters. They all get out and the first words out of the mother's mouth are "I hope it is ok we came.. DD was home from school the last 2 days with a fever and a cough but she really wanted to come.. plus she says she is feeling better (she is 6!). I was in such a shock that she had the nerve to come that I couldn't say anything! plus I had almost 16 girls running around. Thankfully another mom said something like... I would never send my kid to someone else's party if they were sick. They stayed about a half hour, the poor girl coughing her head off they entire time before they left.. Of course it was the talk of the party after she left...
Wouldnt you know that Sat morning ( the day of the family party/cookout) my dd wakes up cranky. By Sat night she had to fever and was up all night coughing. Fever finally went away yesterday but she is still coughing ( post nasal I think) plus she has a stomach ache. So I am keeping her home.
What would you have done?

Something!
As far as I know, no one got lice, but like you, it was the talk of the party. (At least she had treated her, but geez, you kind of want a buffer zone to know that it worked, KWIM?!) Another time, I dropped DD off at someone's house and the father was sick as a dog, and I didn't take my DD home with me (thankfully, she didn't get sick). That's back in the day when I was much more timid. I'm not so much anymore. 
I KNOW how super contagious that king of thing is. 

- hugs for your DD!
