The virus spreads from person to person and can infect a person's spinal cord, leading to paralysis. While many infections result in no symptoms, some cases can lead to severe outcomes, including paralysis and even death.

	Most people infected with the poliovirus do not have any visible symptoms. However, about 25% of infected individuals may experience flu-like symptoms such as sore throat, fever, tiredness, nausea, headache, and stomach pain. These symptoms usually last 2 to 5 days and then go away on their own.		Most people infected with the poliovirus do not have any visible symptoms.

These symptoms usually last 2 to 5 days and then go away on their own.
	In a smaller proportion of cases, the virus can invade the nervous system and cause more severe symptoms, such as paresthesia (feeling of pins and needles in the legs), meningitis (infection of the covering of the spinal cord and/or brain), and paralysis or weakness in the arms, legs, or both. Paralysis is the most severe symptom associated with polio because it can lead to permanent disability and death.

	Diagnosis of polio is based on clinical symptoms and laboratory tests. A sample of throat secretions, stool, or cerebrospinal fluid can be tested for the presence of poliovirus. Molecular techniques such as PCR (polymerase chain reaction) are commonly used to detect the virus.		Diagnosis of polio is based on clinical symptoms and laboratory tests.
