When a child is infected with wild poliovirus, the virus enters the body through the mouth and multiplies in the intestine.It is then shed into the environment through the faeces where it can spread rapidly through a community, especially in situations of poor hygiene and sanitation.ost people infected with the poliovirus have no signs of illness and are never aware they have been infected. These symptomless people carry the virus in their intestines and can âsilentlyâ spread the infection to thousands of others before the first case of polio paralysis emerges.
