Viral meningitis is the least severe type of meningitis, and patients usually recover with no long-term effects from the infection.
Bacterial infections, however, are much more severe, and progress rapidly.
While nonbacterial types of meningitis are more common, bacterial meningitis is the more potentially life-threatening.
The prognosis of meningitis varies between the different causative agents. Meningitis is an inflammation of a certain area of the brain, and in some cases, such as meningococcal meningitis, they can kill within 6 hours of the original onset of symptoms.

Since the word "dangerous" is considered a long adjective (of 3 or more syllables), the words "more" and "most" are used to form the comparative and superlative forms. The comparative form is more dangerous. The superlative form is most dangerous.
Meningitis may be difficult to diagnose. It may occur as spinal meningitis, bacterial meningitis or viral meningitis. Spinal meningitis can only be confirmed by lumbar puncture. There are two divisions of meningitis -- viral (caused by a virus) and bacterial (caused by one of several types and strains of bacteria residing in the throat or nasal passages). The bacterial form of meningitis is extremely dangerous, fast-moving and has the most potential for being fatal. Left untreated, it usually results in death. Threats to infants and children from meningitis include paralysis or death. In adults there is a risk of circulatory problems as well. For many survivors, the long-term effects can be debilitating, possibly including multiple amputations (caused by gangrene), hearing loss, and kidney damage. Heart damage can result from endocarditis. There can also be neurological problems such as epilepsy and learning difficulties. Many (but not all) forms of bacterial meningitis can be prevented in adults by vaccination.

Space travel is statistically the most dangerous form of travel. Overall odds of fatality are approximately 1:120.
Meningitis is most often caused by bacteria, but also can be a viral meningitis or, rarely, caused by a fungus.

* Viral Meningitis - the most common form of meningitis, caused by a viral infection. It occurs mostly in the summer.* Bacterial Meningitis - the less common form of the disease; always associated with serious and severe illness.
