Who is at Risk for Meningitis?

Published in Meningitis Risk Factors 1 min read

Anyone can get meningitis, but certain groups face a higher risk. Several factors increase susceptibility to this infection.

Age Groups at Increased Risk

  • Infants (under 1 year): Newborn babies are particularly vulnerable.
  • Teenagers and Young Adults (16-23 years): This age group shows a significantly higher risk due to increased carriage of bacteria in the nose and throat.
  • Older Adults (over 85 years): Individuals in this age bracket have weakened immune systems, increasing their vulnerability.

Other Risk Factors

Beyond age, several other factors contribute to an increased risk of meningitis:

  • Weakened Immune System: People with compromised immune systems, such as those with HIV or undergoing chemotherapy, are at higher risk.
  • Missing Spleen: The spleen plays a crucial role in fighting infection; its absence increases susceptibility.
  • Crowded Living Conditions: Close contact, such as in college dormitories or military barracks, facilitates the spread of bacteria.
  • Geographic Location: Travel to or living in regions with meningitis outbreaks (like the "meningitis belt" in Africa) significantly raises the risk.

The information above is a summary of findings from multiple sources, including the CDC, WHO, and other reputable organizations. Specific risk factors and the severity of risk may vary depending on the type of meningitis.
