Some common diseases resulting from tick bites include Lyme disease, Rocky Mountain spotted fever and tick-borne relapsing fever, according to MedlinePlus, MedicineNet and the Centers for Disease Control and Prevention. Tick-borne relapsing fever, or TBRF, is a result of infection by borrelia bacteria.
In TBRF, the patient experiences a sudden fever within two weeks of a bite, explains MedlinePlus. The individual suffers from bouts of fever that can last as long as three days. Afterward, the patient may not have another episode of fever for up to two weeks. The episodes of fever often end in a crisis. During the crisis, the patient's body temperature and blood pressure drop, and she suffers chills and sweats profusely. A crisis can result in death.
Lyme disease is also the result of bacteria transmitted by the bite of a tick, notes MedicineNet. Its phases begin at the site of the tick bite and expand into a ring that looks like a bull's eye. Lyme disease affects several bodily systems, including the nervous system, the skin, the joints and the heart.
Rocky mountain spotted fever develops from an infection of the rickettsia rickettsii bacteria, according to the CDC. Its symptoms include abdominal and muscle pain, vomiting, headache, and fever. Although some patients develop the trademark rash, others do not.
