When Is Meningitis Contagious?

Though meningitis isn’t common, it isn’t rare either, and it has different types and causes. Some germs that cause infectious meningitis are contagious, meaning they can spread from one person to another. However, several types of infectious and noninfectious meningitis don’t spread from person to person.

Contagious meningitis infections include: 

• Meningococcal meningitis: The bacteria Neisseria meningitidis causes meningococcal infection.
