Meningitis is a serious medical condition characterized by inflammation of the protective membranes (meninges) surrounding the brain and spinal cord. It is usually caused by viral, bacterial, or fungal infections. Common symptoms include high fever, severe headache, stiff neck, nausea, vomiting, sensitivity to light, and confusion. Bacterial meningitis can be life-threatening and requires immediate medical treatment, while viral meningitis is often less severe. The infection can spread through respiratory droplets, close contact, or contaminated surfaces. Vaccination, good hygiene, and early diagnosis play a crucial role in prevention and reducing complications associated with this potentially dangerous condition.
