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.
