Tetanus
Tetanus is a serious infectious disease caused by the bacterium Clostridium tetani, which is found in soil, dust, and animal feces. It can occur when the bacterium enters the body through a wound, even a minor one.
Here's a detailed but easy-to-understand summary:
Causes
- Caused by Clostridium tetani, a Gram-positive bacterium that produces a toxin called tetanospasmin.
Infection commonly occurs from:
- Deep wounds, lacerations, or punctures from soiled objects
- Burns, accidental wounds, or post-surgical wounds
- Wounds that come into contact with soil or animal feces
Symptoms
- Early Stage (1–7 days after infection)
- Muscle twitching, starting in the jaw ("lockjaw")
- Tightness in the neck and facial muscles
- Wound pain or generalized pain
- Progressive Symptoms
- Muscle twitching in the arms, legs, and abdomen
- Stiffness and arching of the back
- Difficulty swallowing and salivation
- Difficulty breathing, if the respiratory muscles twitch
- Severe Symptoms
- Apnea or irregular heartbeat This can be fatal.
Diagnosis
- Clinical history and symptoms
- Recent wound or exposure to dirt
- Jaw stiffness, muscle twitching
- No specific blood test
- Diagnosis is primarily based on symptoms and history
- Wound or infection testing may be performed to confirm the infection, but is not always necessary.
Treatment
- Wound cleaning and disinfection to reduce infection
- Antibiotics such as metronidazole or penicillin
- Acute immunotherapy (Tetanus Immune Globulin, TIG) to inhibit inactivated toxins
- Muscle spasms can be controlled with muscle relaxants (such as midazolam)
- Hospital/ICU care in severe cases to assist with breathing
Prevention
- Tetanus vaccination (Td/Tdap)
- Children: DTP combination vaccine
- Adults: Booster every 10 years
- Clean the wound immediately and consult a doctor if the wound is deep or dirty
Should or shouldn't: -Get tetanus vaccination as scheduled. Keep the wound clean and seek medical attention immediately if punctured by dirt.
*Should not: Ignore deep or dirty wounds without treatment. This disease can be severe and life-threatening.
Summary
Tetanus is caused by the bacteria Clostridium tetani, which can be transmitted through dirty wounds. It causes muscle spasms, jaw stiffness, and difficulty breathing. It can be prevented with a vaccine and prompt wound cleaning. If the wound is deep, seek medical attention as soon as possible.
