Yesterday I learned that it's possible to get strep throat... on your finger. No, I did not catch this myself. I only heard about it from someone else whose step-sister had this happen to her when her roommate had strep throat. I did not as how this happened either, but you can use your imagination.
She had to take antibiotics for it after it didn't go away. It seems your hands are the most easily infected parts of your body after your face. Fun. As a side note, don't cut your cuticles....
