What Is Meningitis?

Meningitis is an inflammation of the meninges, which are the membranes that cover the brain and spinal cord. It can be caused by a variety of factors, including bacteria, viruses, fungi, and parasites.

Bacterial meningitis is the most serious form of meningitis and can be life-threatening. It is caused by bacteria that enter the bloodstream and then travel to the brain. Bacterial meningitis can cause a range of symptoms, including:

* High fever

* Severe headache

* Stiff neck

* Nausea and vomiting

* Confusion

* Seizures

* Coma

Viral meningitis is less serious than bacterial meningitis and is usually caused by viruses that cause common childhood illnesses, such as mumps, measles, and chickenpox. Viral meningitis can cause similar symptoms to bacterial meningitis, but they are usually milder and resolve on their own within a few weeks.

Fungal meningitis is rare and is usually caused by fungi that live in soil or on plants. It can cause a range of symptoms, including:

* Fever

* Headache

* Confusion

* Seizures

* Weakness or paralysis

* Vision problems

Parasitic meningitis is also rare and is caused by parasites that live in animals. It can cause a range of symptoms, including:

* Fever

* Headache

* Nausea and vomiting

* Diarrhea

* Abdominal pain

* Skin rash

Meningitis can be a serious condition, but it is often treatable if it is diagnosed and treated early. Treatment for meningitis depends on the cause of the infection. Bacterial meningitis is treated with antibiotics, while viral meningitis is usually treated with supportive care, such as rest, fluids, and pain medication.

Meningitis can be prevented by vaccination. There are vaccines available to prevent some of the bacteria and viruses that can cause meningitis. It is important to stay up-to-date on your vaccinations to help protect yourself from meningitis.
