Information on polio vaccination

In Japan, no infection from wild strain virus has been reported since 1994, but those who have not completed inoculation may spread the infection due to the virus import from countries where polio is endemic. Be sure to inoculate.

Polio symptoms

Polio infection is transmitted by the invasion of the virus excreted in human feces, either orally or through the pharynx. The incubation period is 4-35 days.
Most people have no symptoms, but about 5% to 10% have mild upper respiratory tract inflammation or gastroenteritis symptoms called summer cold syndrome, which are prevalent in the summer.
One in 1,000 to 2,000 infected people is paralyzed, and some remain paralyzed forever.
