Fungal meningitis - This type of meningitis is rare. People can get it by inhaling fungal spores from the environment. Cancer, HIV, and diabetes patients are more likely to develop fungal meningitis.
Parasitic Meningitis - Several parasites can cause meningitis and affect the brain or nervous system. It is much less common than other types of meningitis.
Amebic Meningitis - The fatal amebic meningitis caused by the unusual ameba Naegleria fowleri, which dwells in warm water and soil, is rare.

Some meningitis can get better on its own, but some can be life-threatening and would require immediate medical treatment.
This is caused by bacteria called Neisseria meningitides. Symptoms include fever, fatigue, cold hands and feet, rapid breathing, and severe aches in the muscles, joints, chest, or abdomen. In the advanced stages, a dark purple rash appears. Also meningococcal disease and meningitis are not the same. Having meningitis doesn't mean that you have Meningococcal disease, and having Meningococcal disease doesn't always mean that you have meningitis.
Timely medical care must be obtained. Therefore, act immediately if you notice any symptoms.
