Is Lyme disease deadly?

A tick bite can cause Lyme disease. The tick is infected with the Borrelia Burgdorferi bacteria. This bacterium can cause various symptoms in the nervous system, joints, or heart. The infection can occur without any symptoms following. These symptoms appear within one to four weeks after the tick bite. If detected in time, antibiotics can help. Lyme disease itself is not deadly, but the symptoms can be very rarely fatal. In most cases, it results in nervous system disorders.
