Step-by-step explanation:
Aseptic (viral) meningitis is an inflammation of the meninges caused by a viral infection. It is diagnosed by analyzing cerebrospinal fluid (CSF) obtained through a lumbar puncture or spinal tap. The CSF is examined for the presence of abnormal levels of white blood cells and proteins, as well as reduced glucose levels.
Viral meningitis is typically less severe than bacterial meningitis and is caused by various viruses such as enteroviruses, herpes, influenza, measles, and mumps. Most cases of viral meningitis resolve spontaneously, but severe cases can occur. Treatment for viral meningitis focuses on supportive care and managing symptoms.
