Hello! No need to be worried. Unless the squirrel was showing symptoms of Rabies you have nothing to be worried about. I have been bitten by squirrels literally hundreds of times (i'm a licensed wildlife rehabber), the only real concern you should be worried about is infection.. Squirrel bites can be nasty, so make sure you clean it out really well and see a doctor if it appears to be getting infected (redness, feels hot to the touch, oozing puss, intense tenderness at injury site). Rabies in squirrels is incredibly rare. So rare that hospitals won't even precaution-vaccinate you if you go in with a squirrel bite. Most of the animals that carry Rabies, at least up here in the NE, are also nocturnal, so Squirrels don't usually come in contact with those animals, not to mention, if they do get mauled by a sick predator, it's often a fatal encounter, or the squirrel is in serious condition :/
Also, Rabies symptoms in Humans usually show up between 9 days after exposure and 8 weeks... so
if you had been exposed, which i
honestly seriously doubt you were, you would been showing signs by now.. typically the early side effects are tingling/twitching at your injury site and is accompanied by fever, headache, muscle aches, loss of appetite, nausea, and fatigue.
I hope this helps makes you feel a little better and i'm sure more people will pop on in here to assure you
