Meningococcal Disease

Neisseria meningitidisMeningococcal (muh-nin-jo-cok-ul) disease is a serious bacterial infection that most often leads to severe swelling of the tissues surrounding the brain and spinal cord (meningitis) or infection of the bloodstream (meningococcemia). Even with treatment, approximately one out of every 10 people who get meningococcal disease will die, and of those who survive, up to 20 percent will suffer serious and permanent complications including brain damage, kidney damage, hearing loss, and amputation of arms, legs, fingers, or toes.

Anyone can get meningococcal disease but certain people are at increased risk, including:

  • Infants younger than one year old
  • Adolescents and young adults age 16 through 23 years old
  • People with certain medical conditions that affect the immune system
  • Microbiologists who routinely work with isolates of  N. meningitidis, the bacteria that cause meningococcal disease
  • People at risk because of an outbreak in their community

According to the Centers for Disease Control and Prevention (CDC), meningococcal bacteria spread through the exchange of respiratory and throat secretions like spit (e.g., by living in close quarters, kissing). Meningococcal disease can be treated with antibiotics, but quick medical attention is extremely important.

Prevention

Keeping up to date with recommended vaccines is the best way to protect against meningococcal disease. Two meningococcal vaccines (MenACWY and MenB) provide protection against the serogroups that cause most meningococcal disease in the US. CDC recommends meningococcal vaccines for preteens, teens, and people with certain medical conditions, travel plans, or jobs:

  • Meningococcal ACWY vaccine is recommended for all adolescents at age 11-12 years with a booster dose at age 16 years.
  • Teens and young adults (16 through 23 year olds) may also get a MenB vaccine, preferably at 16 through 18 years old. People need multiple doses of a MenB vaccine for best protection and must get the same brand for all doses.
  • Meningococcal B vaccines are recommended for people age 10 years or older who are at increased risk for serogroup B meningococcal disease, including people at risk because of an outbreak.

Talk to your healthcare professional to make sure that your family is fully protected against all serogroups of this deadly disease.
