Isolated meningococcal pneumonia is a rare form of community acquired pneumonia and clinically indistinguishable from other forms except that the organism Neisseria meningitidis is grown from appropriate cultures. It has a mortality rate of less than 9% and is often caused by serogroup Y. It occurs in between 5% and 15% of all patients with invasive meningococcal disease and is thus the second most common non-systemic end-organ manifestation, with cases manifest by either meningococcal meningitis or meningococcal septicaemia being classed differently as their initial management will be different.
Person-to-person transmission of Neisseria meningitidis is a legitimate concern due to droplet spread and so it has significant public health contact and prophylaxis implications. It is a notifiable disease.
