States were considered to have a high incidence of Lyme if they had 100 or more cases per million people in 2019, but the high-incidence baseline for spotted fevers was 50 cases per million people. Both nymphal and adult ticks may be associated with the transmission of pathogens to humans.For the purpose of the map, Insider used different scales to describe the incidence of Lyme disease and Rocky Mountain spotted fever, another tick-borne disease. americanum larvae and nymphs feed on birds and deer. White-tailed deer are a major host of lone star ticks and appear to represent one natural reservoir for E. The lone star tick is primarily found in the southeastern and eastern United States. The lone star tick ( Amblyomma americanum) transmits Ehrlichia chaffeensis and Ehrlichia ewingii, causing human ehrlichiosis, tularemia, and STARI. Adult ticks have been associated with the transmission of R. maculatum larvae and nymphs feed on birds and small rodents, while adult ticks feed on deer and other wildlife. The Gulf Coast tick can transmit Rickettsia parkeri rickettsiosis, a form of spotted fever. The Gulf Coast tick resides in coastal areas of the United States along the Atlantic coast and the Gulf of Mexico. Dogs are the primary host for the brown dog tick for each of its life stages, although the tick may also bite humans or other mammals. Brown dog ticks are found throughout the U.S. rickettsii, causing Rocky Mountain spotted fever, in the southwestern U.S. The brown dog tick ( Rhipicephalus sanguineus) has recently been identified as a reservoir of R. In some regions, particularly in the southern U.S., the tick has very different feeding habits that make it an unlikely vector in the spread of human disease. It is important to note that the pathogen that causes Lyme disease is maintained by wild rodent and other small mammal reservoirs, and is not transmitted everywhere that the black-legged tick lives. scapularis larvae and nymphs feed on small mammals and birds, while adults feed on larger mammals and will bite humans on occasion. This tick is widely distributed in the northeastern and upper midwestern United States. The black-legged tick ( Ixodes scapularis), commonly known as a 'deer tick', can transmit the organisms responsible for anaplasmosis, babesiosis, and Lyme disease. variabilis, although it feeds readily on other large mammals, including humans. Dogs and medium-sized mammals are the preferred hosts of adult D. variabilis larvae and nymphs feed on small rodents. This tick is widely distributed east of the Rocky Mountains and also occurs in limited areas on the Pacific Coast. The American dog tick can also transmit tularemia. Tickborne diseases cannot be spread by person-to-person contact.Īmerican dog tick ( Dermacentor variabilis) is the most commonly identified species responsible for transmitting Rickettsia rickettsii, which causes Rocky Mountain spotted fever in humans. So see your doctor immediately if you have been bitten by a tick and experience any of the symptoms described here. However, early recognition and treatment of the infection decrease the risk of serious complications.

Although easily treated with antibiotics, these diseases can be difficult for physicians to diagnose. Tickborne diseases can result in mild symptoms treatable at home to severe infections requiring hospitalization.

Rash: Lyme disease, southern tick-associated rash illness (STARI), Rocky Mountain spotted fever (RMSF), ehrlichiosis, and tularemia can result in distinctive rashes.

The severity and time of onset of these symptoms can depend on the disease and the patient's personal tolerance level. With Lyme disease, you may also experience joint pain.

Aches and pains: Tickborne disease symptoms include headache, fatigue, and muscle aches.

Fever/chills: With all tickborne diseases, patients can experience a fever at varying degrees and times of onset.

The most common symptoms of tick-related illnesses are:

Diagnostic tests, if indicated by the symptoms and the region where you were bitten.

The geographic region in which you were bitten.

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: Many tickborne diseases can have similar signs and symptoms.

Southern Tick Associated Rash Illness (STARI).

In Arkansas, the tickborne diseases known to occur are: Of the many different tick species found in Arkansas, only a select few bite and transmit disease to humans. In Arkansas, ticks are responsible for more human disease than any other insect, but not all ticks transmit disease.

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.
