Bacterial Meningitis

What is bacterial meningitis?

Bacterial meningitis is inflammation of the lining that surrounds and protects your brain and spinal cord. The inflammation is caused by a bacterial infection and can be life-threatening.

What causes bacterial meningitis?

Bacterial meningitis is caused by bacteria found in the mouth, throat, or nose. The bacteria are spread from an infected person to another by coughing, kissing, or sharing food or drinks. It can also spread from an ear, nose, throat, sinus, or brain infection. A head injury or head surgery may also spread the infection.

Who is at risk for bacterial meningitis?

  • Adults over 60 years of age

  • Young adults between 15 and 24 years

  • Children younger than 2 years of age

  • People with diabetes, cancer, or who have received transplanted organs

  • People who were recently exposed to bacterial meningitis

What are the signs and symptoms of bacterial meningitis?

It may only take a few hours to a few days to have any of the following signs and symptoms:

  • High fever and chills

  • Stiff neck or neck pain

  • Severe headache

  • Nausea or vomiting

  • Red or purple rash

  • Eye pain when you look into bright lights

  • Sleepiness or confusion

How is bacterial meningitis diagnosed?

  • CT scan: This test is also called a CAT scan. An x-ray and computer are used to take pictures of your skull and brain. You may be given dye, also called contrast, before the test. Tell the caregiver if you are allergic to dye, iodine, or seafood.

  • Lumbar puncture: This procedure may also be called a spinal tap. During a lumbar puncture, you will need to lie very still. Caregivers may give you medicine to make you lose feeling in a small area of your back. Caregivers will clean this area of your back. A needle will be put in, and fluid removed from around your spinal cord. The fluid will be sent to a lab for tests. The tests check for infection, bleeding around your brain and spinal cord, or other problems. Sometimes medicine may be put into your back to treat your illness.

  • MRI: This scan uses powerful magnets and a computer to take pictures of your brain. It will also take pictures of the blood vessels and structures in your head. You may be given dye, also called contrast, before the test. Tell caregivers if you are allergic to dye, iodine, or seafood. Remove all jewelry, and tell caregivers if you have any metal in or on your body. Metal can cause serious injury. Tell caregivers if you cannot lie still or are anxious or afraid of closed spaces.

  • Throat culture: This is a test that may help caregivers learn which type of germ is causing your illness. A throat culture is done by rubbing a cotton swab against the back of the throat.

How is bacterial meningitis treated?

  • Antibiotics: This medicine is given to help treat or prevent an infection caused by bacteria.

  • Anticonvulsant medicine: This medicine is given to control seizures. Take this medicine exactly as directed.

  • Fever medicine: This medicine lowers your temperature. Common medicines used to lower temperature include acetaminophen and ibuprofen.

  • Steroids: This medicine may be given to decrease inflammation.

What medical problems can bacterial meningitis cause?

  • Seizure

  • Hearing loss

  • Blindness

  • Heart, kidney, or adrenal gland diseases

  • Coma

How can bacterial meningitis be prevented?

  • Antibiotic medicines may be given if you have been exposed to someone who has bacterial meningitis. You may also receive antibiotics if you have a weak immune system.

  • Discard tissue after you wipe or blow your nose.

  • Wash your hands often with soap and water.

  • Do not share food or drinks.

  • Certain illnesses caused by bacteria can lead to bacterial meningitis. Ask your caregiver if you need any of the following vaccines against illnesses caused by bacteria:

    • Meningococcal polysaccharide vaccine: This vaccine is also called MPV. The vaccine helps prevent certain types of meningococcal disease. The MPV usually is given to adults age 56 years old and older who are at high risk for the disease.

    • Pneumococcal polysaccharide vaccine: This vaccine is also called PPV. It helps prevent pneumococcal disease, such as pneumonia. Adults ages 65 years and older should get the vaccine. People who are at higher risk for pneumococcal disease also may need the vaccine.
