Lyme disease is caused by a bacterium carried by ticks. Early Lyme disease symptoms are flu-like, including fatigue, sore throat, swollen lymph glands, and neck and back pain. A red rash can also occur. After the bacteria spreads through the body, additional symptoms may include joint and muscle pain, and meningitis, Bell's palsy, and nervous system involvement may arise.

Most cases of Lyme disease can be treated with a course of antibiotics, according to the Centers for Disease Control and Prevention, and prevention includes using insect repellent and removing ticks promptly from skin and clothing. This new edition of Lyme Disease covers the latest research known about the disease, its treatment, and its effects on the human body.
