Can you get sick from fishing?

m

So I went fishing the other day out of a lake. Of course I touched a few sunfish/bass and then totally spaced about washing my hands. Then.. I ate dinner.

Now I have a horrible headache, sore throat & earache. I’m just wondering, could it be because of that?

PS: I know this isn’t anything related to periods, but I don’t know where else to post it & couldn’t find anything online :-(
