If you get bitten by a tick, don't immediately assume you've been exposed to Lyme disease.
Ticks can actually carry more than one disease.
Experts say the kind of disease carried by ticks is different in certain regions of the country.
The blacklegged ticks in the northern U.S can spread Lyme disease while the same type of tick in the south is unlikely to bite humans.
In the east, researchers say, ticks carry more than a dozen disease causing agents.
Researchers say if you do get a tick bite, try to save the tick in your freezer or a vial of alcohol and bring it to your doctor.
