Viral Meningitis

What is viral meningitis?

Viral meningitis is inflammation of the lining that surrounds and protects your brain and spinal cord. The inflammation is caused by a viral infection and can be life-threatening. Viral meningitis is also called aseptic meningitis.

What causes viral meningitis?

Viral meningitis is caused by viruses found in sputum (spit), blood, nose drainage, and bowel movements. The virus is spread from an infected person to another by coughing, kissing, or sharing food or drinks. You may also get a type of viral meningitis if you are bitten by a mosquito that carries the West Nile virus. Ask caregivers for more information about how to prevent West Nile virus.

What are the signs and symptoms of viral meningitis?

It may only take a few hours to a few days to have 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 viral meningitis diagnosed?

  • Blood tests: You may need blood taken to give caregivers information about how your body is working. The blood may be taken from your hand, arm, or IV.

  • 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 and stool cultures: A swab of your throat or a bowel movement sample may be collected to learn what virus is causing your symptoms.

How is viral meningitis treated?

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

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

  • Rest: You should rest as much as possible. A dark, quiet room is best if you have headaches.
