What Is Polio?
2. Transmission
Some people will be infected with the virus but show no symptoms at all, however they can still transmit the virus to other people. The virus is transmitted through the feces of infected people, and an infected person can be infectious for weeks before their condition is cured – or before they die.
Polio is often transmitted in food and water that is contaminated with fecal matter that contains the virus. It can also be caught after swimming in water that has been infected. In many cases, the disease is transmitted through direct contact with another person who has the virus.
