Can Hib Cause Injury and Death?

Can Hib cause injury and/or death?

Yes, Hib can cause injury, but rarely causes death. According to Harrison’s Principles of Internal Medicine, the mortality rate for meningitis caused by Hib is around 5 percent. Of survivors, 6 percent of the 5 percent will have permanent sensorineural hearing loss, and about one-fourth will have a significant handicap of some sort. Up to half may have some neurologic problems such as partial hearing loss and delay in language development.1 Acute (life-threatening) complications of Hib can include cerebral edema, increased cranial pressure, ventriculitis (usually in association with obstruction to cerebrospinal fluid flow), cerebritis, hydrocephalus, brain abscess, cerebral infraction, and subdural effusion or empyema.2
