Diagnosis
If you have symptoms of polio, contact a healthcare provider. The healthcare provider will ask you about your symptoms and whether you have traveled recently.
Because polio symptoms look a lot like flu symptoms, the healthcare provider may order tests to rule out more common viral conditions.
To confirm polio, a healthcare provider will take a small sample of:
Cerebrospinal fluid (liquid around the brain and spinal cord).
Saliva from your throat.
Stool (poop).
The healthcare team will look at the sample under a microscope to identify poliovirus.
