Meningitis

Meningitis is a serious bacterial infection that inflames the membranes (meninges) that surround the brain and spinal cord. It can cause a variety of symptoms, including:

* Fever

* Headache

* Stiff neck

* Nausea

* Vomiting

* Confusion

* Seizures

* Coma

Meningitis can be life-threatening if not treated promptly. There are several types of meningitis, including:

* Bacterial meningitis: This type of meningitis is caused by bacteria, such as Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. It's the most common type of meningitis in the United States.

* Viral meningitis: This type of meningitis is caused by a virus, such as enteroviruses, mumps, and measles. It's the most common type of meningitis worldwide.

* Fungal meningitis: This type of meningitis is caused by a fungus, such as Cryptococcus neoformans and Histoplasma capsulatum. It's most common in people with weakened immune systems.

* Parasitic meningitis: This type of meningitis is caused by a parasite, such as Naegleria fowleri and Acanthamoeba. It's rare in the United States.

Meningitis is spread through contact with respiratory droplets from an infected person. It can be spread through coughing, sneezing, kissing, or sharing cups or utensils.

Meningitis can also be caused by a head injury, surgery, or a spinal tap.

Meningitis can be diagnosed with a blood test or a spinal tap.

Treatment for meningitis depends on the type of meningitis. Bacterial meningitis is treated with antibiotics. Viral meningitis is treated with supportive care, such as rest, fluids, and pain relievers. Fungal meningitis is treated with antifungal medications. Parasitic meningitis is treated with antiparasitic medications.
