How does a person contract tetanus?

C. tetani bacteria exist nearly everywhere in the environment, and they can pose a threat when they enter the bloodstream. Open wounds of any kind, including burns and punctures, are potential entry points. People can also get tetanus through insect bites, dental infections, surgery, and intravenous drug use. Newborns can get tetanus if they are born in unsanitary conditions.

Does the protection from tetanus vaccination last forever?

There is no cure for tetanus, and there is no definitive proof that childhood vaccinations will provide you with lifelong immunity. As a result, for the time being, the CDC recommends booster vaccines every 10 years to help your immune system protect against these infections.

Overview

Tetanus, commonly known as lockjaw, is a nervous system disorder characterized by muscle spasms, particularly of the jaw and neck. This infection is caused by the bacteria called Clostridium tetani, which is found in the soil. Tetanus symptoms usually emerge about 7 to 10 days after the initial infection. However, this can vary from 4 days to about 3 weeks, and may, in some cases, may take months.

Open wounds that are soiled, sharing contaminated needles and deliveries in unhygienic conditions are the main risk factors for getting tetanus. Most cases occur in people who did not complete their primary tetanus vaccination schedule or did not receive any booster shot within the previous decade.

Tetanus is a deadly and highly debilitating condition that fortunately can be prevented by timely vaccinations. The tetanus vaccines should be given to children. Primary vaccination schedule consists of 5 tetanus shots given as part of diphtheria and tetanus toxoids and acellular pertussis (DTaP) vaccination in children between 2 months to 6 years.
