So I was biking along a trail when I got a flat 10 miles away. Started walking back to my car and got really thirsty. I drank some creek water but the way I drank it, my nose was slightly submerged for a few seconds. Just the tip, where you'd stick your finger.

6 hours later I start getting a headache I wrote off to dehydration. 24 hours later I still have a headache and slight nausea.

How fucked am I? I'm in Ohio and we've never had a case of this, but apparently Indiana has.
