Haemophilus influenzae type b (Hib) is spread by coughing and sneezing. Many people have Hib bacteria without becoming ill. However, it can cause serious illness, especially in kids under five. Hib disease can cause infections of the joints, skin, and blood, meningitis (swelling of the covering of the brain and spinal cord), brain damage, and even death. Before the vaccine was available, Hib disease was the most common cause of meningitis in kids under five.
Symptoms of illness include:
- High fever.
- Severe headache.
- Stiff neck.
- Quiet or withdrawn behavior.
- Sensitivity to light.
- Vomiting.
- Ear infections.
- Convulsions.
