Haemophilus meningitis is characterized by symptoms including fever, nausea, sensitivity to light, headaches, stiff neck, anorexia, and seizures.

[2][3] Haemophilus meningitis can be deadly, but antibiotics are effective in treating the infection, especially when cases are caught early enough that the inflammation has not done a great deal of damage.

[6] Additionally, siblings of individuals with the Haemophilus influenzae meningitis receive reduced benefits from certain types of immunization.

Common antibiotics include ceftriaxone[2][3] or cefotaxime, both of which can combat the infection and thus reduce inflammation in the meninges, or the membranes that protect the brain and spinal cord.

[citation needed] Survivors of Haemophilus meningitis may experience permanent damage caused by inflammation around the brain, mostly involving neurological disorders.

[10] Children that survive the disease are more often held back in school, and are more likely to require special education services.
