Three if my four kids got the H1N1 this summer at camp. My two daughters were in the same cabin and one of them got it and the other on didn't. My ten year old who is a finger sucker, did not get it. Good immune system I guess.
All of the kids had a sore throat, but different severities,body aches, chills, tons of coughing, some had mucus, some had none, and fever, although not exceptionally high. My thirteen year old even had some dry heaves, but never threw up like the flu. The thing that I noticed the most was how much they slept. More than noormal illness. This may be because of camp as well, but much more than catch up sleep.
My nine year old has severe asthma. The doctor changed his medicine when we went in for the flu testing, because the twice daily steroid he was on seemed ineffective. He did fine. I know the biggest concern is for compromised immune systems. No stand out issues and actually seemed to have the mildest case.
My twelve year old seemed very sick, but nothing that caused me concern. Our family stays pretty healthy overall, so that they were all sick was a bit of a surprise for me.
Finally, my thirteen year old was really hit hard. I wasn't concerned, but he was sick. It took about three weeks for him to get back to his normal self where he wasn't napping almost daily. Fortunately, it was summer.
The sick kids took Tamiflu, and the doctor gave the rest of us preventative Tamiflu prescriptions, which I did not fill because of the cost, and no one else got sick.
It was my husbands busy time of year, at work, with a lot of contact with people from other countries, so he completely stayed away Friday thru Wednesday night in order to have no chance of spreading the illness. The doctor suggested a 5 day quarantine, which we did follow for the kids. I was dilligent about washing my hands and using alcohol wipes upon leaving my house and car.
Hope this was helpful.
