In simple words: Viral meningitis is an infection that causes inflammation of the lining around the brain and spinal cord.It's usually caused by a virus and can cause symptoms like fever, headache, stiff neck, and sensitivity to light. Most people recover fully within a week or two.

Viral meningitis is an inflammation of the meninges, the membranes surrounding the brain and spinal cord, caused by a viral infection.Common symptoms include fever, headache, stiff neck, light sensitivity, and nausea.The condition typically resolves within 7-10 days with supportive care.

Example 1: A 25-year-old patient presents with fever, headache, stiff neck, and photophobia.Lumbar puncture reveals elevated white blood cells and lymphocytic predominance in the cerebrospinal fluid, consistent with viral meningitis.The patient is managed with supportive care, including pain medication and fluids, and recovers fully within a week., A 5-year-old child develops fever, irritability, and lethargy.The child is diagnosed with viral meningitis based on clinical presentation and CSF findings.The child receives supportive care and recovers without complications., A patient with a weakened immune system develops viral meningitis as a complication of another infection.The patient requires hospitalization for closer monitoring and supportive care.

Documentation should include details of the patient's symptoms, neurological exam findings, and results of diagnostic testing, such as lumbar puncture.The specific virus causing the meningitis, if identified, should also be documented.
