Meningitis is primarily a clinical display caused by various factors leading to inflammatory lesions and inflammatory exudation in the meninges. It can be triggered by viral infections, as well as bacterial, tuberculous, or fungal infections. Different pathogens can lead to different symptoms. The initial symptoms of meningitis mainly include the following aspects: First, patients generally experience significant fever, which can range from mild to high and persistent, closely related to the specific pathogen involved. Second, patients will have obvious headaches, as the meninges are irritated, and pain is certain. Third, it usually leads to symptoms of increased intracranial pressure such as nausea and vomiting. Fourth, patients may also experience discomfort and pain in the neck, and upon examination, positive signs of meningeal irritation can be observed.
