Master Common Causes of Meningitis: Children (6 Months - 6 Years) with Picmonic for Medicine

Neisseria meningitidis is spread through the aerosol route between children and has high infectivity. Risk factors for contracting this bacterial infection include preceding illnesses, along with being in close contacts with others, e.g. school or daycare.

H. influenzae type B is another common bacterial cause of meningitis. Due to widespread introduction of vaccinations against this organism, most cases occur in those who are unvaccinated, and in rural or third-world areas where endemic disease is prevalent, leading to a higher exposure in children.

Due to widespread introduction of vaccinations against this organism, most cases occur in those who are unvaccinated, and in rural or third-world areas where endemic disease is prevalent, leading to a higher exposure in children. Children who are immunocompromised or who have had another recent infection may be more susceptible to S. pneumoniae. It is spread via inhalation, so close quarters (schools) increase the risk of transmission.
