http://FungalMeningitis.org - Fungal Meningitis - There are three types of meningitis – viral, bacterial, and fungal. Fungal meningitis is the rarest form of meningitis. It comes from fungus spreading through the blood into the spinal cord. Often the fungus that causes fungal meningitis is Cryptococcus, but that is not the only fungus that can be the culprit. Who Can Get It? - Anyone of any age, race, ethnicity, or gender can get fungal meningitis. That being said, it is most common for people that have a weakened immune system to contract it than for others to do so. AIDS and cancer are often the weakening factors. Some medicines, like prednisone (a steroid) and medicines given after a transplant to ward off organ rejection can also weaken the immune system. So does surgery. Premature babies also have weakened immune systems, especially if they are underweight.
