1. Ty p e s 5 Basic Types of MENINGITIS 1. VIRAL Most common type of meningitis Usually mild and goes away on its own without causing long-term problems Most often caused by a group of viruses called 'enteroviruses," which include common viruses like herpes simplex virus, HIV, mumps, and West Nile virus 2. BACTERIAL Develops when certain types of harmful bacteria either enter the bloodstream and then travel to the meninges (brain and spinal cord), or directly invade the meninges after an ear nfection, sinus infection, skull fracture or surgery Considered the most serious and life-threatening

2. 3. FUNGAL Less common than viral or bacterial meningitis Caused by slow-growing organisms that invade the meninges Usually this results in chronic meningitis 4. PARASITIC Naegleria fowleri is a type of parasite detected all over the world, although it only very rarely causes meningitis This microscopic organism enters the body through the nose and travels to the brain Found in warm freshwater sources (such as lakes, rivers, and hot springs) 5. NON-INFECTIOUS Rarely, meningitis can also be caused by inflammation, chemical irritation or by infiltration of malignant cells
