Stomach flu?

I live in central Florida. Last Friday I started going to the bathroom and it was the worst diarrhea I've had in my life. The nausea and the cramping got severe and by Sunday, I had a 102 degree fever at 1am. It continued up to Tuesday when just based on symptoms, they diagnosed me with a bacterial infection in my digestive tract. 1000CC's of IV fluids and an antibiotic, I feel 99% better. I won't get into all the grosser details, but the symptoms collectively were so unusual to me. Is there something going around? Has anyone else experience this recently? I'm just curious, this just wasn't the same ol' belly bug. It was horrible!
