Poliovirus is an enter virus which is transmitted by the faecal-oral route. The virus is ingested, transits the stomach, and replicates in the lining of the gut where it causes short-term diarrhea. The virus is shed in the faeces for several weeks after resolution of symptoms. In about 1 in 200-1000 cases, the virus escapes the intestine, enters the bloodstream and infects the nervous system where it causes the classic paralytic symptoms associated with the disease. The poliomyelitis (polio) vaccine protects against poliovirus infections. The vaccine helps the body produce antibodies (protective substances) that will prevent an individual from contracting polio.
