Disease class
Tetanus occurs when environmental Clostridium tetani spores germinate in a wound and produce toxin.
Core mechanism
Tetanospasmin disrupts inhibitory neurotransmission, causing rigidity and painful spasms.
Genes or cause
Tetanus is not transmitted from person to person.
Typical features
Trismus, swallowing or breathing difficulty, generalized rigidity, and stimulus-triggered spasms can occur.
Variability
Forms include generalized, localized, and cephalic tetanus; neonatal tetanus is a generalized form.
Diagnosis
Diagnosis is clinical; no laboratory test confirms or rules out tetanus.
Management
Tetanus cannot be excluded when no wound is recalled or wound culture is negative.
Treatment and research
Tetanus is a medical emergency requiring hospitalization and immediate treatment.
Reading evidence
Human tetanus immune globulin neutralizes toxin not yet bound to nerve endings.
Key caution
Care combines wound cleaning and debridement, antibiotics, spasm control, and airway and respiratory support.

For patients and families

A structured guide for understanding the disease and preparing for clinical conversations.

At a glance

Tetanus occurs when environmental Clostridium tetani spores germinate in a wound and produce toxin.

Trismus, swallowing or breathing difficulty, generalized rigidity, and stimulus-triggered spasms can occur.

How the disease works

Tetanospasmin disrupts inhibitory neurotransmission, causing rigidity and painful spasms.

Tetanus is not transmitted from person to person.

Why experiences vary

Forms include generalized, localized, and cephalic tetanus; neonatal tetanus is a generalized form.

Diagnosis and management

Diagnosis is clinical; no laboratory test confirms or rules out tetanus.

Treatment status

Tetanus cannot be excluded when no wound is recalled or wound culture is negative.

Tetanus is a medical emergency requiring hospitalization and immediate treatment.

Reading clinical trials

Recovery does not confer natural immunity, so vaccination is initiated or completed during care.

Topics for a clinical visit

Clinical discussion should cover wound and vaccination history, clinical form, airway risk, immune globulin, and intensive-care planning.
