Who's at Risk? Understanding the Factors That Increase Your Chances of Bacterial Meningitis
Published: Mar 11, 2024
While anyone can develop bacterial meningitis, certain factors can increase your risk. Understanding these can help you take appropriate precautions.
Age Matters
Age is a significant risk factor for bacterial meningitis. Infants, young children, and older adults are at higher risk. In adults, the risk increases after age 50, particularly for certain types of bacterial meningitis like those caused by Listeria monocytogenes.
Weakened Immune System
People with weakened immune systems are more susceptible to bacterial meningitis. This includes individuals with HIV/AIDS, those undergoing chemotherapy, organ transplant recipients, and people taking certain medications that suppress the immune system. Chronic diseases like diabetes can also increase risk.
Environmental and Lifestyle Factors
Certain living conditions can increase the risk of meningitis. These include living in close quarters like college dormitories or military barracks. Smoking and excessive alcohol use can also increase susceptibility to certain types of bacterial meningitis.
Medical Procedures and Conditions
Some medical procedures and conditions can increase risk. These include recent neurosurgery, head trauma, or the presence of a cochlear implant. Certain skull fractures or congenital defects that connect the nasal cavity to the brain can also increase risk.
