All About Tetanus and the Tetanus Shot

2. Tetanus is not contagious from person to person.

Unlike many other diseases like the flu, strep throat, or the common cold, tetanus infection is not contagious from one person to another. Instead, tetanus bacteria generally enter through a break in the skin, such as a cut or puncture caused by a contaminated nail, tack, or thorn (even if it isn't rusty). Tetanus bacteria live in soil, saliva, dust, and manure, so be especially careful if you are working in the garden or with tools that are stored outside.
