When meningitis is caused by Neisseria meningitidis, it is called meningococcal meningitis and when caused by Streptococcus pneumoniae bacteria, it is called pneumococcal meningitis.

Bacterial meningitis is infectious and people get infected when they come in contact with infected patient nose or throat discharge. There are vaccines available for children to prevent occurrence of bacterial meningitis.
People with weak and compromised immune system are at higher risk of been affected. HIV and AIDs patients are at higher risk
