Viral meningitis is an inflammation of the protective membranes covering the brain and spinal cord, primarily caused by viruses. Common viruses that lead to this condition include enteroviruses, mumps virus, and herpes simplex virus. Symptoms often include fever, headache, and a stiff neck, but they are usually less severe than those seen in bacterial meningitis. Diagnosis typically involves a lumbar puncture to analyze cerebrospinal fluid. Most cases of viral meningitis are mild and resolve on their own without specific treatment. Supportive care, such as rest and hydration, is often recommended to help manage symptoms.
