Neisseria meningitidis or meningococcus (serogroups A, B, C, Y, and W-135) is a leading cause of bacterial meningitis. The infection is highly contagious and is spread by airborne droplets and contact with respiratory secretions. Meningococcal meningitis occurs when N. meningitidis from an upper respiratory tract infection enters the bloodstream and causes inflammation of the meninges surrounding the brain and spinal cord. "Hallmark" signs and symptoms include headache, fever and a stiff neck.43
Three quadrivalent vaccines against N. meningitidis serogroups A, C, Y, and W0135 and two serogroup B meningococcal vaccines are available (Table 8). Vaccination is not recommended for an OHCP unless they have a certain risk: 1) asplenia or persistent complement component deficiencies, 2) travel to countries in which meningococcal disease is hyperendemic or epidemic, 3) participate in research OHCP and research microbiologists who might be exposed routinely to isolates of N. meningitides, or 4) any OHCP aged >55 years who have any of the aforementioned risk factors for meningococcal disease are recommended for vaccination.
