Viral meningitis is an infectious disease in which acute inflammation of the meninges is caused by various viral infections, with fever, headache and meningeal irritation as the main clinical manifestations. The course of the disease is generally short, with few complications and a benign course. Viral meningitis has a high incidence in the summer and fall, and can occur year-round in tropical and subtropical regions, mostly in children, with acute or subacute onset. Patients mostly have symptoms of systemic toxicity of viral infection such as fever, photophobia, myalgia, nausea, vomiting, loss of appetite, diarrhea, and general malaise. The body temperature usually does not exceed 40 degrees Celsius, and the older the patient is, the more severe the disease becomes. Younger patients may have a milder or even negative rash cervical tonicity. Adult patients often have severe headache, mostly in the frontal or retro-orbital area, as well as nausea, vomiting, and positive meningeal irritation signs such as cervical tonicity. Some patients may present with symptoms of specific viral infections, such as abdominal pain, diarrhea, sore throat, rash, myocarditis, and mumps. Patients with suspected viral meningitis are advised to have a cerebrospinal fluid examination. The cerebrospinal fluid pressure is mildly to moderately elevated in viral meningitis, with normal or mildly elevated white blood cells, mostly polymorphonuclear cells in the early stages and gradually lymphocytes in the later stages, mildly elevated protein content, and normal sugar and chloride content. Viral meningitis is mostly a benign infectious disease with a short course, and treatment is mainly symptomatic and supportive, usually without sequelae and with a good prognosis, the specific case should be treated under the guidance of a regular hospital doctor.
