Study Notes
Causes and Spread of Meningococcal Infection
- N. meningitidis bacteria can colonize the back of the nose and throat, where they can exist without causing illness in about 1 in 10 people.
- In some cases, the bacteria can migrate to other parts of the body, leading to infection.
- Meningococcal bacteria are transmitted to others through the sharing of respiratory and throat secretions, such as saliva or spit.

- Kissing (close contact)
- Living together (lengthy contact)
