Tetanus (lockjaw)
What is tetanus?
Tetanus is a disease caused by Clostridium tetani bacteria that affects the nervous system.
Commonly called lockjaw, tetanus is now rare in the United States due to widespread
vaccination.
Who gets tetanus?
Tetanus occurs more often in persons who have never been vaccinated against tetanus or who
have not had a booster dose in the past 10 years. Tetanus occurs worldwide but is more
common in agricultural regions of warmer climates, especially where contact with animal
manure is more likely. Neonatal tetanus frequently occurs in developing countries when access
to vaccine and maternity care is limited.
What are the symptoms of tetanus?
Early symptoms include muscular stiffness in the jaw (lockjaw), stiffness in the neck and
abdomen, and difficulty in swallowing. Later symptoms include severe muscle spasms often
lasting for several weeks.
How soon after exposure do symptoms appear?
Symptoms usually begin within 3 days to 3 weeks after exposure with an average of 10 days
after exposure. When symptoms show up sooner, they often are associated with more heavily
contaminated wounds and more severe illness.
How is tetanus spread?
The bacteria that cause tetanus enter the body through a break in the skin, primarily a wound.
It is not spread from person to person.
What is the treatment for tetanus?
Wounds should be thoroughly cleaned. Tetanus Immune Globulin (TIG) is recommended
followed by vaccination with tetanus toxoid. Supportive care and airway maintenance are
critical.
