How fast would one get the Swine Flu H1N1 after being directly exposed to it?

I have the Swine Flu H1N1. I've had it for probably about 4 days. My husband now today is complaining of a sore throat & body aches. I was figuring he probably would get it seeing as we live in the same house & breathe the same air, etc. We'll take him to the doctor tomorrow if he doesn't get better but do you all agree that it seems like he's getting it?
