Several misconceptions about tetanus continue to circulate, often leading to delayed treatment or inadequate prevention. One common myth is that tetanus only occurs from rusty metal injuries; in reality, the bacteria can enter through any contaminated wound, regardless of rust. Another misconception is that once infected, tetanus can spread from person to person — this is false, as tetanus is not contagious. Some also believe that a single vaccine provides lifelong protection, whereas booster doses are required every ten years for continued immunity. Understanding these facts is crucial for effective prevention and timely medical care.
