There's a lot you can do to help prevent meningitis in your teenager. For one, a meningococcal vaccine can help prevent the leading cause of bacterial meningitis in teens. Your teen can also take steps to enhance his or her immune system and to prevent the spread of the disease.
You are bitten by an animal or wounded by an object that might be contaminated with dirt, feces, or dust, and you have not been immunized against tetanus or received a booster within the last five years. Tetanus infection can be fatal and should be treated as soon as possible.
