Possible HIV from toilet?

So i was @ disneyland and i had to use the bathroom pretty bad. I went into the stall and i wiped the toilet seat with toilet paper and i sat down and did my business. two days later when i got home i had a fever of 101.3 F. i had a somewhat sorethroat and a headache. i was shivering pretty bad when i got back into SF. When i got into my bed after taking fever meds it was pretty hot. Could this be a symptom of HIV or a regular fever. BTW before we left i was swimming in the morning around 8 o clock. There was a jacuzzi and a reg pool and i switched bak and forth from it. Help??
