18. Fungal Meningitis
While there are many things that can attack the body, a fungus can do more than some think. They can save lives, such as the case of how we discovered what we know now as the antibiotic medication, Penicillin. This accidental discovery by Alexander Fleming saved the lives of millions, with more antibiotics branching off of it. Yet fungi have also taken lives as well, putting through some severe illnesses. One of them is known as Fungal Meningitis.
While normal meningitis is pretty bad, it’s usually bacterial and can be treated relatively easily. Fungal meningitis has many of the same symptoms and has to be treated with antifungal medications. Yet, it’s also possible to have this version of meningitis longer. Since it is a fungus, some wild chemist or biologist could add whatever they needed to it in order to give certain things to the person who will be infected by it. Possibly then creating our real zombie apocalypse scenario.
