Tips on staying classy while interviewing despite having a cold?

I have a cold, and I have an interview tomorrow. I’m not feeling horrible today, but as the cold has only just set in, I’d say all bets are off as far as how I’ll feel tomorrow.

I definitely don’t think wiping my nose every two seconds would make the right impression. If my nose is runny tomorrow, how do I deal with that? Handkerchief? Enormous supply of Kleenex?

And no hand-shaking, I presume. Any other tips?

Thanks.
