What is another name for tetanus infection?

Tetanus infection is commonly referred to as "lockjaw." This nickname originates from one of the most notable symptoms of tetanus, which is muscle stiffness and spasms, particularly in the jaw muscles—leading to difficulty in opening the mouth. The inability to relax the jaw can give the appearance of a locked or rigid state, hence the term "lockjaw." Tetanus itself is caused by a toxin produced by the bacterium Clostridium tetani, which enters the body through wounds. Understanding this term is important for recognizing the serious nature of the infection and the importance of vaccination in preventing it.

The other terms mentioned in the choices refer to different diseases or conditions altogether. Chickenpox is a viral infection characterized by an itchy rash and blisters. Strep throat is an infection caused by bacteria that leads to a sore throat. Measles is another viral disease marked by a distinctive rash and flu-like symptoms. Each of these conditions is unrelated to tetanus and serves to reinforce the unique aspects of the infections they describe, highlighting the importance of terminology in medical contexts.
