How is tetanus contracted?

How is tetanus contracted?

• A. From dirty wounds contaminated with soil containing Clostridium tetani spores
• B. Through contaminated water
• C. Through airborne transmission from sick individuals
• D. Through eating undercooked meat

Answer: (A)

Tetanus is contracted when Clostridium tetani spores enter a wound, especially a dirty wound that is contaminated with soil. In such wounds, the anaerobic environment allows the spores to germinate and the bacteria to produce tetanospasmin, a powerful toxin that travels to the nervous system and blocks inhibitory signals, leading to the characteristic muscle stiffness and spasms. This disease is not spread from person to person, so it isn’t acquired through contaminated water, airborne transmission, or eating undercooked meat. Understanding this helps explain why wound care and vaccination are key preventive measures: proper cleaning of wounds and keeping up with tetanus vaccines prime the immune system to neutralize the toxin if exposure occurs.
