I got hep A as a teenager. I contracted it through food - somebody didn't wash their hands well and I got it.

I didn't feel well for a couple of weeks, but I was young & dumb & kept pushing. When I finally collapsed (almost literally) they ran blood tests & found it. So, I was in bed for quite awhile.

This was in the 70's, mind you, so I'm sure there are better treatments available. Oh, and the only thing on TV was Watergate. On all three channels. Yes, boys & girls, only three channels.
