Meningococcal disease is a serious infection caused by Neisseria meningitidis, also known as meningococcus, a gram negative diplococcus.[1] Meningococcal disease includes meningitis, meningococcal septicemia, or a combination of both, which can be life-threatening and rapidly progressive.[2] If left untreated, the disease has a high mortality rate; however, it is preventable through vaccination.[3] Meningitis and meningococcal sepsis are major causes of illness, death, and disability in both developed and under-developed countries.

Meningococcal disease can be transmitted to others through saliva, close contact with an infected individual by inhaling respiratory air droplets.[4] Initial symptoms may be subtle and similar to other bacterial infection, but can quickly progress to include fever, rash, body aches, photophobia and other complications.[2][5] Neisseria meningitidis colonizes a substantial proportion of the general population without issues, but it can invade the bloodstream, affecting the entire body, most notably limbs and brain, causing serious illness in a small percentage of individuals.[6]

The global incidence of meningococcal disease is relatively low, ranging from 0.0 to 10.2 per 100,000 however cases in the United States are rising.[2][7] Serotypes of the bacteria range from various countries, with serotype B accounting for most new cases worldwide.[2] Meningococcal vaccines have sharply reduced the incidence of the disease in developed countries.[8]

Vaccine has also shown to lessen cases of illness and their associated complications as well as death.[9] Current vaccinations cover most of the bacterial strains that causes meningococcal disease. This has led to a decrease of incidence and burden from the disease. Treatment include supportive care, early administration of antibiotics and management of complications associated with infection.[10] Ongoing research continues in an effort to understand specific aspects of meningococcal biology and host interactions; however, the development of improved treatments and effective vaccines is expected to depend on novel efforts by workers in many different fields.[6]
