Which group has the highest rate of meningococcal infection?

The group with the highest rate of meningococcal infection is young adults. This demographic, particularly those living in close quarters such as dormitories or military barracks, is more susceptible to the bacteria that cause meningococcal disease. These environments facilitate the spread of infections due to the close physical contact and higher interaction rates among individuals.

Additionally, young adults are often in a phase of life where they may be at increased risk due to lifestyle choices, such as smoking or social behaviors that may involve high rates of exposure to respiratory pathogens. Public health studies have consistently shown that incidence rates peak in this age group, highlighting the importance of vaccination and awareness efforts aimed at young adults.

Conversely, while infants and toddlers also have a notable incidence of meningococcal infection, it is typically lower compared to young adults in communal living situations. Older adults experience meningococcal infections much less frequently due to factors like a generally stronger immune response to certain infections and lower exposure risk.
