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.

To obtain or inquire about an immunization record, or for general immunization information, please contact your local public health unit.
