A disease generally spread through the bite of a tick. This causes an irritable red rash around the bite mark. Other early symptoms are flu-like, including fatigue, slight fever, stiffness or pain in muscles and joints, especially in the neck and jaw, swollen glands and reddening of the eyes.

Later symptoms include irregular heart beat, pain in the joints, dizziness, and weakness in face muscles.

The disease is cause by a bacteria called Borrelia burgdorferi. Antiboitics are generally effective. Multiple cases are possible.
