Viral infections are the most common cause of meningitis, with bacterial infections being the second most common cause. Additional and more rare causes of meningitis include parasites, fungi, and causes that are non-infectious such as ones related to drugs. Meningitis caused by a viral infection is sometimes referred to as, 'aseptic meningitis,' and is serious, although rarely fatal in people with average immune systems. The symptoms of viral meningitis usually last between 7 and 10 days, and people often experience a complete recovery.
