Soar throat and diarrhea?

I started out 2 days ago with a really dry throat and now its been hurting pretty bad but I also started in with diarrhea for over 2 days its just pure water not clear and it smells really horrible.I woke up this morning with a low grade fever too. Alls I want to do is sleep for hours. What could I have and is there anything I can take. I have been sipping on 7 up but it hurts to swallow.
