Facts and Information

Tickborne Disease (TBD) is a type of zoonotic disease (an infectious disease transmitted between animals and humans) that is transmitted by ticks, a member of the arachnid family of insects. In Arkansas, ticks are responsible for more human disease than any other insect, but not all ticks transmit disease. Of the many different tick species found in Arkansas, only a select few bite and transmit disease to humans. Click here to learn more about the different kinds of ticks and where they are found.

In Arkansas, the tickborne diseases known to occur are: Anaplasmosis, Rocky Mountain Spotted Fever, Ehrlichiosis, and Tularemia. While Lyme disease is an important tickborne disease, ticks in Arkansas do not currently transmit Lyme disease. However, individuals who have travelled to other parts of the country, especially the Northeast and Midwest, might have become infected while traveling.

Many tickborne diseases can have similar signs and symptoms. If you have been bitten by a tick and develop the symptoms below within a few weeks, a health care provider should evaluate the following before deciding on a course of treatment: 
  • Your symptoms
  • The geographic region in which you were bitten
  • Diagnostic tests, if indicated by the symptoms and the region where you were bitten
The most common symptoms of tick-related illnesses are: 
  • Fever/chills: With all tickborne diseases, patients can experience fever at varying degrees and time of onset.
  • Aches and pains: Tickborne disease symptoms include headache, fatigue, and muscle aches. With Lyme disease you may also experience joint pain. The severity and time of onset of these symptoms can depend on the disease and the patient's personal tolerance level. 
  • Rash: Lyme disease, southern tick-associated rash illness (STARI), Rocky Mountain spotted fever (RMSF), ehrlichiosis, and tularemia can result in distinctive rashes.
Tickborne diseases can result in mild symptoms treatable at home to severe infections requiring hospitalization. Although easily treated with antibiotics, these diseases can be difficult for physicians to diagnose. However, early recognition and treatment of the infection decreases the risk of serious complications. So see your doctor immediately if you have been bitten by a tick and experience any of the symptoms described here.
Tickborne diseases cannot be spread by person-to-person contact.
