How is it spread?

Meningococcal disease is contagious. It is spread through the exchange of respiratory secretions during close contact such as kissing or coughing on someone. Although meningococcal bacteria are very dangerous, they cannot live outside the body for very long. This means the infection is not as easily spread as a cold virus.

About one in ten people carry meningococcal bacteria in their nose or throat without showing any signs or symptoms of the disease. These people can unknowingly transmit the bacteria to others.
