Haemophilus influenzae type b (Hib)

Haemophilus influenzae type b (Hib) causes bacterial meningitis and can also cause other serious infections of the throat, lungs, blood, joints and bones. .

Meningitis is an infection of the tissue and fluid that cover the brain and spinal cord.

The infection was originally named Haemophilus influenzae because it was incorrectly thought to cause influenza (the flu).

The bacteria are commonly called Hib. Without treatment, all children with Hib meningitis die. Even with treatment, death occurs in about 1 out of 20 cases. About 1 in every 3 survivors has detectable brain damage.

The dramatic decreases in Hib infections are an immunization success story. Even though the risk is low in Canada, it is important to keep immunizations up to date.
