I just heard that a friend was bitten by a tick that she found embedded in her skin and she found the tell tale bull’s eye mark in the area. She fears that she may have Lyme disease and is being treated with antibiotics. She was lucky because she found both the tiny tick and the tell tale bull’s eye. Not everyone is so lucky to find this evidence. This is her second encounter with a tick that carries a disease. The last time she had a tick borne disease called Babesiosis. Ticks can carry numerous diseases, not just Lyme disease and/or Babesiosis. See here.
Because ticks carry or are what is called a vector for numerous diseases, you can get different tick borne diseases. And you can get these tick borne  diseases in many parts of the world as well as in all states in the US. See here.
