Tetanus (lockjaw) is caused by the bacteria Clostridium tetani. The spores are commonly found in soil, dust and feces. A person can become infected with tetanus when the spores enter the body through broken skin such as a puncture wound, cut, animal bite or burn. Tetanus is characterized by muscle spasms, seizures, fever and may result in death. In Ontario, a vaccine series to prevent tetanus is started in infancy with booster doses throughout life.
