Here is an overview of meningitis epidemics in the United States.

Meningitis is caused by inflammation of the protective membranes (called meninges) that cover the brain and spinal cord. The inflammation is usually caused by an infection of the fluid surrounding these areas.

There are five types of meningitis: bacterial, viral, parasitic, fungal and non-infectious.

Bacterial meningitis is contagious and comes in several different strains.

Viral meningitis is less serious and occurs more frequently than bacterial meningitis.

Fungal, viral, parasitic and non-infectious meningitis is not contagious and does not spread from person to person.

Fungal and parasitic meningitis are rare.

The most common causes of meningitis are viral infections, when a virus travels to the brain after entering the system through the nose or mouth.

Bacterial meningitis begins as a cold-like infection and is spread through respiratory and throat secretions, such as saliva and phlegm.

People contract fungal meningitis by inhaling the affected spores.

Contamination of food, water and soil can lead to parasitic meningitis.

Noninfectious meningitis can be caused by physical injury, cancer, systemic lupus, and certain medications.

Enteroviruses, the most common cause of viral meningitis, are most often transmitted from person to person through fecal contamination or through the respiratory secretions of an infected person.

Symptoms usually present quickly for some types of meningitis and include high fever and chills, mental status changes, nausea and vomiting, sensitivity to light, headache, and stiff neck .

Bacterial meningitis is treated with antibiotics.

Viral meningitis is treated with bed rest, plenty of fluids, and painkillers for body aches.

Fungal meningitis is treated with antifungal drugs.

Parasitic meningitis is less common and most cases have been fatal.

Vaccines are available to protect against certain types of viral and bacterial meningitis.
