Bacterial Meningistis in Children

  • Bacterial Meningitis is when the thin membranes that cover the brain and the spinal cord are inflamed. These thin membranes are called Meninges! 

  • Not including infants in the neonate stage, the three most common bacteria that cause acute bacterial meningitis are streptococcus pneumonia, Neisseria meningitis, and Hib Haemophilus influenzae.

  • Pneumococcal bacteria is now the number 1 cause of community acquired bacterial meningitis at 1.1 cases per 100,000 population overall, the rate has decreased by 59% since 2000 when the Pneumococcal conjugate vaccine came out.

  • While Pnuemococcal meningitis is responsible for 1.1 cases per 100,000 of the overall population Hib Meningitis is at .2 cases per 100,000 of the overall population.

  • In the  united states there are 2,600 sproadic cases of Bacterial meningitis reported each year.

  • It is estimated that 70 percent of those cases are children under the age of 5 years of age.

  • Pneumococcal bacteria is the cause of 4,800 of invasive pneumococcal disease infections in children younger then 5 years of age.

  • 5% of those children will die due to the illness.

  • The mortality rate for neonatal bacterial meningitis is 15-20%.

  • The overall mortality rate for Bacterial meningitis is 5-10%.

  • Pneumococcal Meningitis has the highest mortality rate at 26.2-30%.

  • The second highest mortality rate is Hib meningitis at 7.7-10.3%

  • Lastly, N. Meningitis (mono) has the lowest mortality rate at 3.5-10.3%.
