Bacteria causes this type of meningitis. This is the most common kind of meningitis after the viral type. Children from 1 month to 2 years old are at particular risk for bacterial meningitis.
It can be deadly and requires immediate medical attention. There are several vaccines available that can help fight against certain types of bacteria that cause bacterial meningitis.
Among the types of meningitis is fungal meningitis. This rare type is caused by inhaled fungal spores. It can develop when the fungus spreads throughout the body and reaches the brain or spinal cord. People with weak immune systems are more prone to this type of meningitis.
Following this, people with compromised immune systems should avoid contact with soil, and activities that allow contact with bird and bat droppings (ex. cave exploration)
Parasites cause this rare form of meningitis. Normally, these parasites infect animals and not people. But by eating the infected animals or any contaminated food, people can catch the disease. There is no specific medication for parasitic meningitis. Pain medication can manage headaches and other mild symptoms.
Also known as Primary Amebic Meningitis (PAM), this infection of the brain is rare and potentially fatal. A free-living ameba called Naegleria fowleri causes this infection. The ameba thrives in soil or bodies of warm freshwater such as hot springs, warm lakes and rivers, water heaters or poorly maintained swimming pools. It enters the body through the nose, usually when swimming, then travels up to the brain and infects brain tissues. To reduce the risk of infection, limit the amount of water that goes up to the nose while swimming.
There are certain conditions where meningitis is not caused by infection. These noninfectious causes can be certain types of cancer, lupus, inflammation due to head injury or after brain surgery, or drug-induced.
