Were you looking for information about Poliovirus? Polio virus is a common misspelling of poliovirus.
Poliovirus is a highly contagious virus that causes the medical condition polio. When a person is infected with this virus, it is expected that transmission among susceptible household contacts will occur in nearly 100 percent of children and more than 90 percent of adults. Transmission most often occurs through contact with stool of the infected person (known as fecal-oral transmission). Less frequently, poliovirus can be spread through contact with infected respiratory secretions or saliva (oral-oral transmission).
When a person is infected with poliovirus, the virus resides in the intestinal tract and mucus in the nose and throat. Following infection, a person does not immediately become sick. Once poliovirus enters the body, it travels to the back of the throat, nose, and intestines, where it begins to multiply. It can also travel to other parts of the body. Symptoms of poliovirus usually appear after 7 to 14 days.
