| Haemophilus influenza meningitis | <disease> A form of meningitis caused by the bacterium haemophilus influenza. Inflammation of the membranes (meninges) covering the brain and spinal cord can result after infection with this organism. Influenza meningitis occurs most frequently in children under 5 years old. Onset may be sudden or occur more slowly after an upper respiratory infection. Symptoms and features include fever, headache, stiff neck, photophobia and mental status changes. Infants may be irritable and exhibit poor feeding associated with fever. Severe cases may progress to seizures, coma and death. Treatment always includes high-dose systemic antibiotics and corticosteroids may also be used in some select cases. (27 Sep 1997) |

| Haemophilus influenzae | <bacteria> Bacterium sometimes associated with influenza virus infections, causes pneumonia and meningitis. (18 Nov 1997) |
| haemophilus influenzae type b | The majority of type b isolates are from biotype I. The organism can cause life-threatening meningitis, primarily in children 6-12 months of age. Children with underlying disease or immunodeficiency are also at high risk for infection. A vaccine is available and recommended for children under 5 years of age. (12 Dec 1998) |
