The prognosis for meningococcal meningitis is fair if the patient does not have focal neurologic deficits and is not stuporous or comatose. The prognosis for meningococcal disease is poor when the infection has a septicemic component. Most patients with meningococcal meningitis recover completely if appropriate antibiotic therapy is instituted promptly.

Thrombocytopenia, a lowered coagulation index, moderate anemia (hemoglobin < 11 g/dL), an obtunded mental state, and a history of convulsions were reported to be poor prognostic factors.

In one study, only anemia was correlated independently with fatality; the results suggested that anemia should be considered an important prognostic marker in the acute phase of meningococcal meningitis.
