Tick-borne fever is an illness caused by bacteria transmitted through the bite of infected ticks. Common symptoms include fever, headache, muscle aches, and fatigue. The disease is often found in wooded or grassy areas where ticks thrive. Diagnosis typically involves a blood test to identify the bacteria. Treatment usually consists of antibiotics, which are effective if started early. Preventive measures include wearing protective clothing, using insect repellent, and checking for ticks after spending time outdoors.
