Tetanus, often referred to as lockjaw, is a serious infection caused by the bacteria called Clostridium tetani. While rare in developed countries due to widespread vaccination efforts, tetanus remains a significant concern in areas with limited access to healthcare and vaccination programs. Understanding the causes, symptoms, treatment and prevention of tetanus is crucial for public health awareness and management.
Clostridium tetani, the bacterium responsible for tetanus, is commonly found in soil, dust, and animal faeces. The bacteria enter the body through wounds or cuts, especially deep puncture wounds, burns or any injury where the skin is broken. Once inside the body, the bacteria produce toxins called tetanospasmin, which affect the nervous system, leading to muscle spasms and stiffness characteristic of tetanus.
As the infection progresses, muscle spasms can become severe, leading to respiratory difficulties, which can be life-threatening if left untreated.
Treatment for tetanus involves a combination of wound care, medications and supportive therapy.

Prevention of tetanus primarily involves vaccination and wound care:

![]() Prompt cleaning and treatment of wounds to remove dirt, debris and bacteria reduce the risk of tetanus infection. Tetanus vaccination status should be updated if necessary after sustaining a wound. |
Tetanus is a serious but preventable disease caused by bacteria commonly found in the environment. Understanding the causes, symptoms, treatment and prevention of tetanus is essential for both healthcare providers and the general public.
Vaccination, proper wound care and prompt medical attention are key strategies in controlling and preventing tetanus infections. By raising awareness and ensuring access to vaccines and healthcare services, we can work towards minimizing the impact of tetanus worldwide.
