Persons at Risk for the Disease, Including College Students

Meningococcal disease can affect people at any age. Infants are at the highest risk for getting the disease. Disease rates fall through later childhood but begin to rise again in early adolescence, peaking between the ages of 15 and 20 years.

Due to lifestyle factors, such as crowded living situations, bar patronage, active or passive smoking, irregular sleep patterns, and sharing of personal items, college students living in residence halls are more likely to acquire meningococcal disease than the general college population.

In addition to increased risk because of crowded living situations, proximity to a person diagnosed with disease (e.g., being a household contact) also increases one’s risk of disease. Other factors also increase risk, such as a compromised immune system (which might be caused by HIV/AIDS or taking certain chemotherapy or immuno-suppressants) or having no spleen. Even something as simple as a respiratory tract infection may increase the risk of getting the disease. Certain genetic risk factors also may increase susceptibility to infection.
