Meningitis

Meningitis is an inflammation of the meninges, which are the thin layers of tissue that cover the brain and spinal cord. It can be caused by a variety of infectious agents, such as bacteria, viruses, fungi, and parasites. Symptoms of meningitis may include fever, headache, confusion, stiff neck, and vomiting. If left untreated, meningitis can be deadly. Treatment depends on the cause but may include antibiotics and other medications, as well as supportive care, such as fluid replacement and oxygen. Vaccines are available to prevent some of the most common causes of meningitis, such as bacterial meningitis. Meningitis is an important cause of illness and death worldwide, and recognition of its signs and symptoms is critical in order to provide early diagnosis and prompt treatment.
