    How are these diseases diagnosed?

    Blood, urine, throat, and stool tests are done to determine if a person has been infected with any of these diseases. Sometimes a lumbar puncture is required to obtain cerebrospinal fluid, biopsies or imaging studies such as X-rays, MRIs and CT scans to make the diagnosis.
