====== Meningococcal disease ======

Meningococcal disease describes infections caused by the bacterium [[Neisseria meningitidis]] (also termed meningococcus). It has a high mortality rate if untreated but is vaccine-preventable. While best known as a cause of [[meningitis]], it can also result in [[sepsis]], which is an even more damaging and dangerous condition. Meningitis and meningococcemia are major causes of illness, death, and disability in both developed and under-developed countries.
