Meningitis is a relatively common infectious disease of the central nervous system in clinical practice. The common types of meningitis seen clinically include viral meningitis, tuberculous meningitis, and purulent meningitis. The main clinical symptoms of meningitis include headache, nausea, vomiting, fever, and signs of meningeal irritation; some may present with focal neurological deficits in symptoms and signs. If meningitis is not treated promptly or the treatment is ineffective, it often leads to significant sequelae, and can even endanger the patient's life. Therefore, meningitis is considered a serious disease of the central nervous system. If diagnosed with meningitis, timely treatment is essential, underscoring the seriousness of the disease.
