What causes polio?
Polio is caused by poliovirus. The virus enters the body through the mouth. t is transmitted by contact with an infected person’s faeces (stool), or by exposure to phlegm or mucus when an infected person coughs or sneezes. Polio can also be spread by touching items which are contaminated with faecal matter containing the virus and then putting your hands in your mouth. Poor hygiene or unsanitary conditions leading to contamination of food or water supplies with the virus have also been linked to polio outbreaks.
A person who is infected with the virus can remain contagious for 1 or 2 weeks after symptoms first appear. An infected person can carry the virus and infect others even if he or she does not appear to be sick.
