Answers: What is tetanus and how does it affect the body?

• tetanus infection mechanism
• Clostridium tetani spores
• tetanus toxin and interneurons
• historical accounts of tetanus
• tetanus vaccination and prevention

What it concludes

• Tetanus does not pass from person to person but infects the body through cuts and abrasions.
• Clostridium tetani spores can survive for years in soil, manure, and dead leaves.
• Tetanus toxin blocks neurotransmitters released by interneurons, causing uncontrollable muscle contractions and spasms.
• Without treatment, tetanus has an extremely low rate of survival, often leading to asphyxiation within 72 hours.
• Tetanus vaccines, developed in the early 1920s, are crucial for preventing tetanus and stopping its spread.
• Vaccinating mothers during pregnancy helps prevent tetanus in newborns.
