Tick fever is a common term used to describe a range of diseases caused by bacteria transmitted by ticks. These illnesses go by different names depending on the specific bacteria involved. For example, Rocky Mountain spotted fever, Q fever, and Lyme disease are all caused by different types of bacteria transmitted by ticks. Symptoms of tick fever can include fever, fatigue, headaches, muscle pains, and rashes, among others. It is important to take precautions to avoid tick bites when spending time outdoors, such as wearing protective clothing and using insect repellent. If you develop symptoms of tick fever after a tick bite, seek medical attention promptly.
