S.F.
Tics are all over outdoors. Unless you see some bumps-bites in a centralized area or a rash, there is no infection or disease transmitted. That is what the doctor is going to look for. There is a test for lyme disease. There is more than one type of disease that is possible to be contracted from tics. See the below articles on sypmtoms, prevention and treatment.
