Meningitis
(from the National Institutes of Health)

Meningitis is an infection of the membranes (called meninges) that surround the brain and spinal cord.

Symptoms, which may appear suddenly, often include high fever, severe and persistent headache, stiff neck, nausea, and vomiting.

Changes in behavior such as confusion, sleepiness, and difficulty waking up are extremely important symptoms and may require emergency treatment.

In infants symptoms of meningitis may include irritability or tiredness, poor feeding and fever.

Meningitis may be caused by many different viruses and bacteria. Viral meningitis cases are usually self-limited to 10 days or less.
