What Causes Bacterial Meningitis
Bacterial meningitis is an infection of the membranes that surround the brain and spinal cord. It is caused by bacteria that enter the body and travel to the meninges, where they multiply and release toxins that cause inflammation and swelling. The most common bacteria that cause meningitis are Neisseria meningitidis (also known as meningococcus), Streptococcus pneumoniae (also known as pneumococcus), and Haemophilus influenzae type B (Hib). How is Bacterial Meningitis Spread? Meningitis can be spread through close contact with respiratory secretions, such as saliva, mucus, or sputum, from an infected person. It can also be spread through close contact with an infected person's respiratory secretions or by sharing items that have come into contact with their respiratory secretions, such as a cup or utensil. In some cases, it can be spread through the air when an infected person coughs or sneezes. People who are at higher risk for bacterial meningitis include: ● Infan
