I figured why make a new thread when most here who went will be checking this thread.
I have found out that there were a few people at Dragon*Con that had or got H1N1(Swine Flu). I was around one of them apparently though I did not get sick. *shrug*
This is nothing to panic about. Still if you haven't been feeling the greatest since D*Con and you haven't been getting better, it's best to get checked out by a physician to be sure. Also just because you didn't get sick, it doesn't mean you can't spread it. Anyone you know that's gotten sick since your return, please let them know to get checked out too. Just as a precaution.
Stay safe and be healthy.
