Meningitis caused by Haemophilus influenzae

Meningitis Caused by Haemophilus influenzae

Meningitis is inflammation of the membranes that cover the brain and the spinal cord and is caused by an infection with various organisms including bacteria, viruses, fungi, and parasites. Meningitis can be caused by Haemophilus influenzae, a type of bacteria that is spread through contact with respiratory secretions, such as saliva.

This type of meningitis is sometimes referred to as Hib (Haemophilus influenzae type B) infection. Young children under age 5 are most susceptible to Hib meningitis. Signs and symptoms include fever, headache, stiff neck, nausea, and confusion.

Hib meningitis can be prevented with a vaccine. Treatment usually involves antibiotics to kill the bacteria.

Complications of Hib Meningitis

Hib meningitis can cause life-threatening complications, including brain damage, hearing loss, seizures, and death. Complications may include:

  • Hearing loss
  • Seizures
  • Learning disabilities
  • Cognitive developmental disabilities
  • Speech difficulties
  • Mental health problems
  • Brain damage

If the infection is not treated quickly, there is an increased risk of complications and death. The risk is higher in young children and in people with weakened immune systems.


The Hib vaccine is the best way to prevent Hib meningitis. The vaccine is typically given as part of the routine childhood vaccination schedule. It is generally well tolerated and is safe for most people.

Preventing Hib meningitis with the vaccine is the best way to protect you and your family. It is important to follow the recommended vaccine schedule and to keep up to date with booster shots if they are advised.


Hib meningitis is a serious infection that can cause long-term complications, including brain damage, hearing loss, seizures, and death. Vaccination is the best way to protect against Hib meningitis and its serious complications.
