The most common pathogens of viral meningitis are enteric or respiratory viruses, mostly transmitted by fecal-oral, respiratory route. There are more than 60 subtypes of enteroviruses, including mainly coxsackieviruses and polioviruses. Mumps virus, varicella-zoster virus, or influenza virus can also cause viral meningitis, but it is relatively rare clinically. Viral meningitis occurs in summer and fall, and is more common in children. Patients may present with symptoms of systemic toxicity, manifesting as fever, muscle pain, loss of appetite, generalized weakness, or meningeal irritation signs, manifesting as headache, vomiting, and neck stiffness. The treatment of viral meningitis includes symptomatic treatment, and the patient is given drugs for dehydration and lowering cranial pressure. If the patient is in severe pain, analgesics can be given. If the patient has seizures, drugs such as carbamazepine or phenytoin sodium can be given, and antiviral therapy can be given if necessary.
