Depends on the type: Most people have a distorted view of "meningitis" since most are familiar with the fearsome "meningococcal" form, caused by neisseria meningitidis bacteria. In fact, many, types of meningitis (bacteria, virus, etc) are not contagious just by merely standing beside a person. It depends on how an organism cause a meningitis and how intact a person's immune system is in fighting the offending agent.

Meningitis: Causes of bacterial meningitis including strep, neisseria, h flu & viruses like enteroviruses, herpes, & hiv. Bacteria & viruses that cause meningitis colonize the nose & throat & are transmitted through respiratory droplets. Viral meningitis can also be transmitted by fecal-oral routes & insect bites. Usually contacts working within ~3 ft of those with meningitis r considered to be at high risk.
